New Cards

As a reminder, the Bohrok were introduced in BBTS as an archetype of Flip monsters with massive potential for swarming and removal, mainly shackled by the fact that there’s inherently a turn of delay in starting a Flip-based engine. The Kal extension tries to cover for this weakness by providing an alternative gameplan to establish turn 1 disruption or deal with established boards turn 2, by means of Rank 4 Bohrok-Kal and Link-1 Krana-Kal.

But before we get into the additions to those Extra Deck groups, here are some new Main Deck cards to help as well.

Bohrok-Kal Strategy

Continuous Spell

When this card is activated: You can Special Summon 1 “Bohrok” monster from your hand. Once per turn, if a “Bohrok” monster(s) is Special Summoned to your field (except during the Damage Step): You can activate 1 of these effects, or, if you control a “Bohrok” Xyz Monster, you can activate both, in sequence;
●Target 1 other Spell/Trap on the field; destroy it.
●Add 1 “Bohrok” Spell/Trap from your Deck to your hand, except “Bohrok-Kal Strategy”.
You can only activate 1 “Bohrok-Kal Strategy” per turn.

Bionicle: Protodermic Evolution (v4.3.3)

Bohrok-Kal Strategy is perhaps the key piece for consistent combos on your first turn, bringing out a Bohrok from hand when first activated and then immediately triggering off that Summon to either destroy a Spell/Trap or search an archetypal one – or both if you have a Bohrok-Kal out. The first of these options is purely lore, referencing the Kal’s theft of the Nuva Symbols (which are here Continuous Spells with negative effects when destroyed), while the latter is purely utility, letting you find essential Bohrok support cards without spending too much deck space that they really need for monsters.

One of the best search targets is the newly added Counter Trap, Bohrok Counterattack (yes, the new Battlin’ Boxer card can technically search this too).

Bohrok Counterattack

Counter Trap

When your opponent activates a Spell/Trap Card, or monster effect, while you control a “Bohrok” monster or only face-down monsters (min. 1): Send 1 “Krana” monster from your Deck or Extra Deck to the GY; negate the activation, and if you do, you can attach that card to 1 “Bohrok” Xyz Monster you control as material.

Bionicle: Protodermic Evolution (v4.3.3)

This one represents the most straightforward form of the turn 1 disruption I’m trying to add – just a classic omni-negate that can be used both to protect your dormant Bohrok waiting to flip and to back up the swarms in action. Note that it does not destroy what it negates, so unless you have a Bohrok-Kal to attach to, this will let your opponent keep their monsters and continuous cards. Would be a bit too good otherwise, given its fairly low requirements and lack of HOPT.


Now for the stars of the show: Two more Bohrok-Kal join Gahlok-Kal to complete half of the team already.

Bohrok Tahnok-Kal

Xyz Effect MonsterRank 4 | FIRE Machine | ATK 2100 / DEF 2200

2 Level 4 “Bohrok” monsters
Place materials detached from this card on the bottom of the Deck, instead of sending them to the GY. Once per turn: You can attach 1 “Krana” monster from your hand, field, or GY to this card as material. (Quick Effect): You can detach 1 material from this card, then target 1 face-up monster your opponent controls; it cannot attack or activate its effects this turn, also you can detach 1 more material from this card, and if you do, destroy all monsters your opponent controls with less than 2000 ATK. You can only use this effect of “Bohrok Tahnok-Kal” once per turn.

Bionicle: Protodermic Evolution (v4.3.3)

Tahnok-Kal, just like its base form, offers monster destruction as a Quick Effect, but looking at official media makes it quite clear that its electric powers were actually not really used for destructive purposes as much as to stun its enemies. At the same time, I can’t in good conscience make the Lightning Bohrok-Kal not have some kind of built-in Raigeki, so here’s the compromise I ended up with: Detach 1 to stun a target monster for the turn, and then on resolution, you can detach another to blow up all of your opponent’s monsters below the 2000 ATK “Toa threshold”. This is also an extra balancing factor on this very powerful effect for a Rank 4, since it means removing it from the field before it resolves will stop the destruction.

Bohrok Nuhvok-Kal

Xyz Effect MonsterRank 4 | EARTH Machine | ATK 2000 / DEF 2300

2 Level 4 “Bohrok” monsters
Place materials detached from this card on the bottom of the Deck, instead of sending them to the GY. Once per turn: You can attach 1 “Krana” monster from your hand, field, or GY to this card as material. You can detach 2 or more materials from this card, then choose that many Main Monster Zones and/or Spell & Trap Zones on the field; return as many cards in those zones to the hand as possible, also those unused zones cannot be used until your next Standby Phase. You can only use this effect of “Bohrok Nuhvok-Kal” once per turn.

Bionicle: Protodermic Evolution (v4.3.3)

Nuhvok-Kal, in contrast, is slow, but armed with Gravity powers that are hard to resist and cover a wide range. I thought through a few concepts for this, but the one that won out is just a mass bounce (“floating” cards up off the field) limited only by material count that also locks zones in reference to base Nuhvok (“crushing” the land with supergravity). I kind of wanted to have something with flipping face-down in there as well, but couldn’t quite make it worthwile on a “slow” ignition effect. Fun Fact: This one can be really rude against Pendulum decks in particular.

Test footage of these two new bosses can be found in the below demo videos I posted earlier this month.


The Krana-Kal have also been brought up to half-completion, but in their case that means 3 rather than 2 new ones, for a total of 4 (out of 8).

Krana Vu-Kal, Transporter

Link Effect MonsterLink-1 [↘] | DARK Zombie | ATK 0

1 “Bohrok” or “Krana” monster
Cannot be used as Link Material. Once per turn: You can target 1 Level 4 “Bohrok” monster this card points to; Special Summon from your Extra Deck 1 “Bohrok” Xyz Monster using that target as material. (This is treated as an Xyz Summon.) A “Bohrok” Xyz Monster that has this card as material gains this effect.
●Once per turn (Quick Effect): You can banish this card until the End Phase, and if you do, you can add 1 “Bohrok” card from your GY to your hand.

Bionicle: Protodermic Evolution (v4.3.3)

The Vu-Kal grants flight like its base version, but also enhanced speed, so rather than “dodge” things with targeting protection, it more literally lets its Bohrok-Kal dodge instantly off the field, optionally recycling a card in the process to live up to its name of “Transporter”. As a downwards-pointing Krana-Kal, its utility effect provides a way to Xyz Summon with only a single Level 4 Bohrok, which can then attach the Link Monster as its second material. This card is part of my current preferred turn 1 play, where I use it to make a Tahnok-Kal that can, on the opponent’s turn, activate the banish effect in chain before its own Quick Effect, letting you detach both materials to blow up the field while still getting a card back with the effect granted by the Vu-Kal.

Krana Su-Kal, Demolisher

Link Effect MonsterLink-1 [▲] | DARK Zombie | ATK 0

1 “Bohrok” or “Krana” monster
Cannot be used as Link Material. If an opponent’s monster this card points to battles a “Bohrok” monster, that opponent’s monster’s ATK/DEF become 0 during the Damage Step only. A “Bohrok” Xyz Monster that has this card as material gains this effect.
●This card gains 800 ATK/DEF and cannot be destroyed by card effects.

Bionicle: Protodermic Evolution (v4.3.3)

The upwards-pointing Krana-Kal, such as the Su-Kal, bring back a possibly familiar effect previously seen on the Servants of the Swarm, some technically-not-Bohrok (and thus kind of unplayable) cards from BBTS. A monster they point to will be brainwashed into voluntarily surrendering to the Bohrok in battle, setting its stats to 0 so it can easily be hit over. All of this is continuous, so it can out a gargantuan range of threats, assuming you can safely get it and a Bohrok to the Battle Phase. The actual power granted to a Bohrok-Kal using this Krana-Kal is as simple as it gets: Super strength (+800 ATK/DEF) and resistance to heat and cold (effect destruction protection).

Krana Za-Kal, Overseer

Link Effect MonsterLink-1 [↗] | DARK Zombie | ATK 0

1 “Bohrok” or “Krana” monster
Cannot be used as Link Material. If an opponent’s monster this card points to battles a “Bohrok” monster, that opponent’s monster’s ATK/DEF become 0 during the Damage Step only. A “Bohrok” Xyz Monster that has this card as material gains this effect.
●Once per turn, when a card or effect is activated that would destroy a “Bohrok” card(s) you control (Quick Effect): You can detach 1 material from this card; negate the activation, and if you do, destroy that card.

Bionicle: Protodermic Evolution (v4.3.3)

The Za-Kal has the same on-field utility effect and grants the power of telepathy, which turns Bohrok-Kal into budget Stardust Dragons. Sounds strange, but the background to that is that the original Krana Za allowed you to protect a Bohrok from destruction by shuffling back another monster, to represent the squad coordination it enables. Now plain old protection would have been redundant when the Su-Kal does that and more, so instead it shuts down destructive effects against all your Bohrok by detaching (and thereby shuffling back) an Xyz Material. This is a little less convenient than it sounds because it requires the effect to be one that would destroy a card from the archetype, so you won’t be able to chain it to anything that could theoretically be resolved in such a way that it only destroys unrelated cards (e.g. the average DPE activation).

Updated

The updates this time are simple, just refining the first drafts of the Bohrok support a bit now that I’ve worked my way deeper into it.

4.0.4

Bohrok Gahlok-Kal

Xyz Effect MonsterRank 4 | WATER Machine | ATK 2200 / DEF 2100

2 Level 4 “Bohrok” monsters
Place materials detached from this card on the bottom of the Deck, instead of sending them to the GY. Once per turn: You can attach 1 “Krana” monster from your hand, field, or GY to this card as material. At the start of the Battle Phase: You can detach 1 material from this card, then target 1 face-up monster on the field; that target cannot attack until the end of the next turn, also you can equip 1 other monster on the field to it. You can only use this effect of “Bohrok Gahlok-Kal” once per turn.

Bionicle: Protodermic Evolution (v4.0.4)
4.3.3

Bohrok Gahlok-Kal

Xyz Effect MonsterRank 4 | WATER Machine | ATK 2200 / DEF 2100

2 Level 4 “Bohrok” monsters
Place materials detached from this card on the bottom of the Deck, instead of sending them to the GY. Once per turn: You can attach 1 “Krana” monster from your hand, field, or GY to this card as material. At the start of the Battle Phase: You can detach 1 material from this card, then target 1 face-up monster on the field; that target cannot attack until the end of your turn, also you can equip 1 monster adjacent to it or in its column to it. You can only use this effect of “Bohrok Gahlok-Kal” once per turn.

Bionicle: Protodermic Evolution (v4.3.3)

As I said the moment it was first released, it’s just thematically super neat to have the range of Gahlok-Kal‘s “magnetism” limited to adjacent zones or the same column, so I ended up doing just that. And sure enough, it made zero difference in testing, partially because AI doesn’t understand how to play around things and partially because I can always just put a monster in the column myself. Oh yeah, and the attack restriction now always lasts until your End Phase only, so you can’t block an opponent’s monster by targeting it on your turn. This way it’s more of a downside to targeting something on your own field than additional benefit for an already powerful removal effect.

4.0.4

Krana Ja-Kal, Tracker

Link Effect MonsterLink-1 [◀] | DARK Zombie | ATK 0

1 “Bohrok” or “Krana” monster
Cannot be used as Link Material. You can Tribute this card; Special Summon 1 Level 4 “Bohrok” monster from your hand or GY, but shuffle it into the Deck if it leaves the field. A “Bohrok” Xyz Monster that has this card as material gains this effect.
●Once per turn: You can detach 1 material from this card, then declare 1 card name; your opponent cannot activate cards, or the effects of cards, with that original name, until the end of their turn.

Bionicle: Protodermic Evolution (v4.0.4)
4.3.3

Krana Ja-Kal, Tracker

Link Effect MonsterLink-1 [◀] | DARK Zombie | ATK 0

1 “Bohrok” or “Krana” monster
Cannot be used as Link Material. You can Tribute this card; Special Summon 1 Level 4 “Bohrok” monster from your hand or GY in face-up or face-down Defense Position, but shuffle it into the Deck if it leaves the field. A “Bohrok” Xyz Monster that has this card as material gains this effect.
●Once per turn: You can declare 1 card name; until the end of your opponent’s turn, “Bohrok” cards and Set cards you control are unaffected by the effects of cards with that original name.

Bionicle: Protodermic Evolution (v4.3.3)

For the Ja-Kal, both effects got some significant changes. First, the tag-out was buffed to also allow Special Summoning in face-down Defense Position, so you can use it as a way to prepare the Flip engine without needing to commit an actual Set action to it. This is, for example, relevant when using Bohrok-Kal Strategy, since activating it, Special Summoning a Bohrok, searching a Spell/Trap, and then using Ja-Kal to put that Bohrok face-down leaves you in a significantly better spot than just setting the monster right away.

The effect to block a card by declaring its name did always feel a bit too oppressive, so I ended up nerfing that part by bringing it more in line with the original Krana Ja and just granting your Bohrok (and face-down) cards immunity to the declared name instead. In exchange, it’s now free, so you can keep the materials attached for more important purposes.


A deck update, rather than a card update, was forced from me by Konami’s ruthless (but honestly deserved) banning of Spright Elf, thus rendering the last version’s Toa Nuva deck illegal. Due to the strict collective HOPT on all the Kanohi Nuva, conducting a Fusion Summon on the opponent’s turn is kind of super important if you want to use your resources optimally, so I needed something that could replace Elf’s role in setting that up. A card that can bring back Energized Protodermis Chamber as a Quick Effect, while also being consistently accessible through the basic Isolde combo. And I can proudly report that I have found it.

https://www.duelingbook.com/deck?id=12178919

In fact, it wasn’t very far from the Elf-shaped hole in the decklist at all: Within the same archetype, there’s Spright Double Cross, a Trap with multiple effects including GY revival, searchable by Spright Jet and therefore via Gigantic Spright, which can be made in the standard combo line after the first Toa Nuva by overlaying Isolde with a leftover C.C. Matoran (we play Hafu now to ensure the latter is available). Gigantic Summons Jet and Jet adds Double Cross, and if you further link those two into I:P Masquerena, you even get an additional way to interact for your trouble.

Now of course, with Hafu, Jet and Double Cross, that means three extra bricks we need to run, and after all is said and done this only works once, unlike Elf’s infinite revival forever and ever. The deck’s definitely worse now that it has lost one of its central pieces, but I’m also kind of glad it happened because it reminded me that it probably isn’t a good idea to make all the recursion dependent on some external card. That’s why the next update will contain, in addition to the remaining Toa Nuva, a card that provides this functionality in-archetype. Probably. More or less. We’ll see how it turns out.

Designer’s Quip: The Unintended Jahnok Combo

Splashability is when a card or group of cards can be used outside their own deck/archetype to achieve benefits in combination with entirely unrelated cards. Taking this into account when making custom cards adds a lot of depth and therefore fun to the process while also achieving more balanced results, but for a long time I didn’t really do that. So once in a while I have the funny experience of looking back at older designs and realizing they do something generically useful I wasn’t actually going for. Here’s one such example.

Bohrok Tahnok can shuffle itself into the Deck to destroy a face-up monster, and this is a Quick Effect. Already seems quite useful, but between having to return to the Deck, the limitation of the targets to only face-up monsters, the fact that it targets at all, and the lack of a built-in way to easily bring it out, it probably wouldn’t be that good to just splash it into random stuff.

In comes the second card of this package, the Krana Ja. By discarding it from your hand while you control a Bohrok, you can scout ahead and render everything that is already visible on your opponent’s field ineffective during the following turn, and like many other Krana it can return from the field to your hand during Main Phase 1 to bring out a Bohrok from the Deck at the cost of immediately ending the turn.

The bottom line is that by just getting a Krana Ja on the field somehow in your Main Phase 1 (e.g. with One for One or simply a spare Normal Summon), you can easily out any single monster that can have its effects negated. Return the Ja to your hand to Special Summon a Tahnok from your Deck, activate the Ja from your hand during the immediately ensuing End Phase (since you do have a Bohrok now), then in the following turn activate the Tahnok’s Quick Effect to target and destroy whatever you like. At this point all protection and/or negation on your opponent’s field will be negated by the Ja, so you don’t have to worry about that stuff at all.

Now, this does ultimately cost you your Battle Phase and only takes care of a single monster, so it probably isn’t really that impactful in the grand scheme of things. But I found it pretty funny that these two cards on their own could pull this off even though neither of their designs was in any way geared towards it. The Tahnok just has a Quick Effect because it’s fast, and the Krana Ja does what it does because it’s literally a Scout.

Theme Guide: Krana (BBTS)

The eight types of Krana are sentient, organic beings that provide the guiding intelligence as well as a set of special powers to the Bohrok swarms, so the BBTS expansion implements them as monsters that allow Bohrok access to some effects that are generally a bit more clever than what the archetype otherwise does. Each Krana essentially has two effects: One that activates in the hand and is different for each monster while following one of two templates, and another that can only be one of two options, each of which is shared by half the Krana.

Let’s just use those second effects to segment the Krana in the following explanation and cover the rest as we go.

Based off the idea that Bohrok are really just robot suits piloted by the Krana inside them, these monsters have the ability to return themselves from the field to the hand to get any of the Level 4 Bohrok directly from the Deck. This is not something you want to rely on unless you need to since it only works during your Main Phase 1 and then ends the turn, but having the option at least avoids total bricks when playing a lot of Krana.

Regarding the first effect, the Krana Yo and Krana Ca follow the template of equipping themselves to a Level 4 or higher Bohrok from the hand in order to grant some continuous benefit. The Yo, holding the power to let its Bohrok dig through most substances, allows the equipped monster to attack directly. The Ca with its shielding powers protects all of your Bohrok from battle, but only once per turn for each.

Krana Xa and Krana Ja feature the alternative effect template, which means you can activate them by sending them directly from the hand to the GY at a certain timing. With the Xa, which are mainly in charge of formulating the more complex strategies of the plans, you can counteract negations or other responses to your Bohrok effects. It can be activated in any chain that has a Bohrok monster’s effect anywhere but as the last link and will negate the effects of all non-Bohrok cards on the field that appear in this chain. This lasts all the way to the end of the turn, so you might be able to disable something vital using this if you can just bait an activation out of it first. Another mass effect negation option is provided by the Krana Ja, which gives the swarms advance warning of known threats and thus renders everything that is visible on your opponent’s field useless during the following turn. This effect can be activated at any time as long as you control a face-up Bohrok, so you’d probably want to use it during the End Phase for maximum effect.

The other group of Krana are those that can banish themselves from the GY to steal a monster destroyed by a Bohrok from your opponent’s GY, controlling their enemies to make them part of the swarm. The monsters are Special Summoned in face-down Defense Position for thematic reasons and there’s a restriction on it that effectively prevents you from doing it more than once per turn, but even with that it’s obviously a damn strong move.

The equipping Krana among these are the Krana Za and Krana Su. The squad leader-type Za allow Bohrok to communicate and coordinate telepathically, which in this case is used to protect the equipped monster via strategic retreats of your other monsters (including face-down ones) while also keeping up the card supply. The Su is the caveman among the Krana, merely granting a stat boost, but that is very versatile in its simplicity, especially considering the equipping is a Quick Effect.

The pure hand effects here belong to Krana Vu and Krana Bo. The Vu makes Bohrok capable of flight, so it can be used to dodge targeting effects and even goes as far as negating and destroying the card in question to really make your opponents think twice about targeting your Bohrok with anything. The Bo can be triggered in response to your Bohrok cleaning up any card with their removal effects, using its night vision capabilites to track down further copies of the same card hiding in the darkness of your opponent’s hand and get rid of them for good.

On the topic of Krana that can steal your opponent’s monsters, we should take another look at Bohrok Confrontation, which was already covered in the main Bohrok article. What it does is send a Krana from your Deck to the GY to boost a Bohrok’s ATK/DEF, and knowing what we do about Krana now, the idea is obviously to have a Bohrok run over a monster in battle and then immediately steal it with the Krana.

There are other cards that further expand on the idea of Krana mind control. The following four monsters, for which I like to use the umbrella term “Servants of the Swarm”, represent the unwilling victims of this power.

Bohrok Servant is the generic standin for arbitrary beings under the control of a Krana. Its purpose is basically to make immediate use of the face-down monsters you get from the stealing effect, by contact fusing them (remember, that works when face-down) with a Krana from pretty much anywhere, banishing both and giving you a monster that at least copies the stats of whatever you stole.

The remaining Servants of the Swarm are a bit more specific, each of them being based on one particular inhabitant of Le-Koro that was possessed by a Krana during the takeover of that village. They generally work by sending a Krana from the Deck to the GY to neutralize an opponent’s monster and set up a situation where you can easily steal it, though the way in which they do so differs greatly.

Matoran of the Swarm counters Xyz Monsters by attaching to them as a material, which locks their effects and makes their ATK/DEF become 0 during battle with a Bohrok. It can also attach itself from the GY to your Xyz Monsters that are flipped face-up, obviously so a stolen Xyz can actually have material.

Turaga of the Swarm interferes with Synchro Summons in a particularly funny way, inserting itself on the opponent’s field in place of a Tuner and immediately forcing a Synchro Summon. When used as material, it gives you control of the Summoned monster for a turn and permanently makes it so its ATK/DEF become 0 when battling a Bohrok. This approach comes from the fact that Turaga were originally Tuners, so now that the BCOT remake is changing them to Link Monsters this card might be due for a redesign sooner or later as well.

Toa of the Swarm is the simplest of these, since it just Tributes over an opponent’s high-level monster and then surrenders itself willingly by making its ATK/DEF 0 when battling a Bohrok. The Level restriction was already iffy to begin with and is even more so when considering the prevalence of Link Monsters, so I might eventually tweak that to something like “2000 or more ATK”.

Finally ,we have a funny little card that simultaneously supports and counters Bohrok/Krana decks. Krana Pit lets you protect a card from destruction each turn by banishing a Krana monster from the GY instead, but since this works on both GYs you can just as well use it if your opponent is the one playing Krana. Similarly, it allows recovering a banished monster when there are 2 or more Krana banished, without specifying whose Krana they must be.

Conclusion

Krana add quite a few sophisticated effects to the Bohrok toolbox, giving you interesting options to interact with your opponent beyond just razing their field to the ground. The ability to steal a destroyed monster makes the Bohrok’s effects and attacks a bit more threatening than they already were, and with the Servants of the Swarm can itself be made into a central strategic element of your deck.

A selection of Krana can be found sprinkled throughout the sample Bohrok decks in the BBTS release, while the Servants of the Swarm usually appear as Side Deck options.
