Theme Guide: (Exo-)Toa (BBTS)

After collecting all types of Krana and descending into the depths of the Bohrok Nest to stop the swarms for good, the Toa Mata came across a new power to aid them in this quest, sealed deep beneath the earth. Suits of armor equipped with powerful weaponry, at the cost of inhibiting their innate elemental powers.

The Exo-Toa, like the Boxor used by the Matoran, is represented by a Union Monster, but like the Toa, it’s Level 6, so getting it on the field where it can do all the Union stuff is the first challenge. The built-in solution is being able to Special Summon itself if all monsters you control are Normal Summoned Toa, though in hindsight it probably wouldn’t be broken to drop the “all monsters” part. Anyway, equipping it gives an enormous boost of 2000 ATK, but comes with two downsides. First, it negates the monster’s effects (i.e., the “elemental powers”), and second, it robs the Toa of their individuality by replacing their name with “Exo-Toa”. Which, due to the little clause at the start of the card text that I’m pretty sure has never actually been used in history (because why would it?), means the are not technically “Toa” monsters anymore and thus lose access to archetypal support cards. This, unfortunately, includes the Kanohi (even in their most recent and well thought out form as of the time of this writing), which canonically shouldn’t be affected by the armor. Might have to come up with something to fix that.

As if this wall of text wasn’t enough, the Exo-Toa has a final consistency-boosting effect to make sure it’s capable of carrying the frankly kind of useless original Toa Mata designs to playability: After going to the GY, it Sets Exo Armaments from the Deck during the End Phase. And once the next turn starts, you can immediately use this Trap Card to bring out a Toa Mata from your hand and equip it with an Exo-Toa from Deck or GY, completing the package in one shot. This also conveniently makes it so the effect negation is actually relevant on the old versions of the Toa Mata who only had on-summon effects, since this way the negation is already active when that effect tries to resolve.

Once in the GY, the Trap turns into what it really takes its inspiration from, namely the array of equipment found on an Exo-Toa. The “boxing claw” works similar to the Boxor (just because of the name) and prevents your opponent from using effects while an Exo-Toa (which could be the Union Monster itself or a Toa that has been equipped and renamed) battles. The armor simply grants protection as you would expect it to. And the electro rocket flies in a straight line to destroy something in the same column as an Exo-Toa, which can be two columns with one copy if you set up the zones correctly when equipping (one from the equip card, one from the equipped monster). Do note that all of these are Quick Effects due to this being a Trap Card.

So the Exo-Toa has many powerful features, but in the story, they were not enough to overcome the combined power of the Bahrag. And I did indeed design the cards specifically so nothing they do can actually out the Bahrag when paired up with both their protection effects online. Because that requires an ability that can only be used when the Toa shed the armor and return to their own elemental powers.

The Toa Seal is the ultimate finishing move achieved when six Toa of different elements combine their powers, imprisoning whatever is unfortunate enough to be in the middle in an inescapable mass of crystalline Protodermis. Accordingly, this card requires six Toa to activate, but due to Yugioh’s Attribute lineup not quite containing the boatload of elements Bionicle has, we will settle for different names. And since getting 6 monsters on the field is only technically possible, you may also pick from those in your hand and GY, though those will be banished on resolution. The result is a non-targeting mass banishing of up to 6 cards, which easily gets past the mutual protection of the Bahrag queens and wipes out pretty much everything else while it’s at it. The number of cards banished from the hand is limited by the number of Normal Summoned Toa participating in the seal, because just banishing 6 from the hand specifically sounded a bit too broken even with these difficult requirements.

The final new card on the Toa’s side is The End of the Swarm, and it’s a … kinda weird one. Assuming you have a Toa, it grants you the choice between two effects relating to Level 8 or higher monsters (?). One temporarily banishes (??) one of those to recover a Continuous Spell (???) from the GY. The other locks a number of your opponent’s monsters depending on your Level 8+ count into face-down Defense Position and basically makes your monsters go UCT on them, except continuous.

Now I can reveal that the second of these effects represents the deactivation and subsequent cleanup of the Bohrok, referenced in the name of the card. Face-down is their sleeping state, so they get switched into that, and the rest is mostly to bypass their Flip effects because this would be kind of self-defeating otherwise. As for what is going on with these Level 8 or higher monsters, Continuous Spells, and the entire first effect, I will remain quiet. Just enjoy the foreshadowing and wait for the answer to your questions to one day rock your universe (okay, that might be overstating it a bit).


While the Toa Mata are currently undergoing a total redesign in order to make them playable on their own, this was actually one of my first attempts to fix those old designs by introducing a small, consistent combo that they could use in the likely event that Plan A (just somehow summoning a lot of Toa) didn’t work out. It provides a 4k+ ATK beater who, with the Exo Armaments correctly set up in the GY, has access to either an effect lockdown during battle, protection against both destruction and targeting, and a limited Quick Effect destruction. Nothing crazy, but at least good enough to actually start getting somewhere in most games.

Once the BCOT overhaul is done and the Toa Mata are fully updated with a more competent strategy, these cards may have to be adjusted for that. But in the meantime, you can find a sample deck using both them and the old Toa in the BBTS release.
