BCOR expands the Matoran archetype beyond the special case of the Chronicler’s Company, with the addition of six iconic villagers of different occupations and a few support cards.
Leading the charge is the mightiest scion of Ta-Koro, Jaller his name*. The captain of the guard, in accordance with his occupation, helps you assemble a fighting force with an extra Normal Summon and prepares them for battle against your opponent’s monsters with a potentially really big ATK boost.
* Or Jala at this point, actually. I originally wanted to only use the final version of any changed names for consistency across expansions, but later decided there wasn’t really any point to that. Jala, Maku, etc also technically are canon due to Naming Day, so it makes more sense to keep them in. Since BCOR is from before that change of plans, it still uses the final names.
Another source of significant benefits for groups of Matoran is Hewkii (Huki), Koli Champion of Po-Koro. His abilities can be summarized as taking the attention of his opponent’s monsters off his fellow Matoran, persevering through difficult battles as long as he has others to protect, and potentially pulling off an unexpected victory agains particularly powerful enemies. Very champion-like, though in hindsight I feel the last effect shouldn’t really work when attacking.
With Rahi being the central focus of the BCOR expansion, it only seems correct to also examine the more peaceful side of the Rahi/Matoran relationship from the perspective of the Matoran. That brings us to the following two villagers, whose occupations both utilize tamed Rahi.
Onepu summons out an “Ussal” (here broadly represented by Beasts or Winged-Beasts in general) from the Deck and “rides” it, increasing his power in battle. This is a Special Summon from Deck covering the Level 4 or lower range of two entire Types without any restrictions such as negated effects, so basically the only reason I could have possibly thought this was remotely ok was because I didn’t for a single second consider how to break it. If you have read the Rahi guide, you might note that Ussals are indeed Beast, but the addition of Winged-Beast to this effect is a bit puzzling. The explanation is that I wanted the two Rahi-related Matoran from this set to build upon each other’s effects, so I made sure to have both of their effects use both relevant types.
Hence, Kongu has the ability to pilot whatever Onepu has summoned by turning it into an equip card for himself. Riding his glorious flying (yes the Beasts fly too shut up) steed, he will then pass over enemy lines to attack directly, and while he’s at it take out some of the more vulnerable monsters. Furthermore, even if he’s taken out, his steed will still be there to fight for you.
Hahli is designed to quite literally assist her fellow Matoran, letting herself be Special Summoned if you control them and protecting them from effect destruction. On top of that, she can search Matoran once per turn. Not even hard once per turn. And the Special Summon can be repeated as much as you want, too. Definitely another case where the card’s existence proves I don’t think things through very well.
Matoro the Matoran, whose name holds the same energy as Hubert the Human, is a straightforward revival option, and he brings back not one, but two Matoran. In exchange, it only works during the turn he was Normal Summoned and requires him to sacrifice himself. So basically ;_;7
The fact that he’s a Tuner comes from his job as Nuju’s translator, based on the original version of the Turaga being Tuners as well.
In addition to these six monsters, BCOR enriches the Matoran archetype with a small lineup of supporting Spell Cards.
Probably the most important is the Vuata Maca Tree, the natural power source utilized by the villages of Mata Nui. Being a feature of the location, the tree requires a Field Spell to support its continued existence, though a one-time use is fine anyway. Its effect utilizes the highly entertaining excavation mechanic to either Special Summon Matoran (and their other forms) from hand/GY or add one that you happen to find.
Perhaps a bit less central to Matoran society on Mata Nui, but still a lot more present in official material are Lightstones, which are the focus of our final pair of cards.
The Lightstone itself has various effects related to illumination, first and foremost making both players reveal their hands for a turn. If you activate this while your hand is bigger than your opponent’s, you unfortunately reveal more information than you get, but to make up for that difference, additional effects of the Lightstone begin to apply. In total, it can potentially let you see and reorder the top of the opponent’s Deck, see all their Set cards, and explode into some burn damage on the next draw (which you can set up with the reordering), so there’s definitely an argument to be made that the extra information revealed on your part is worth it.
Cavern of Light, being the location where Lightstones are mined, provides easy access to them, as you would expect. It also establishes the actual connection to the Matoran archetype by replenishing used-up Lightstones as long as you have the required miners or simply creatures of the EARTH to dig them up.
BCOR introduces various Matoran support cards that provide aid in playing a deck composed of Matoran, Turaga, and Toa from across Mata Nui, but in doing so produces a few honestly quite broken effects. Also, this concept was already kind of used for the Chronicler’s Company in BCOT and was a lot more appopriate there than on other Matoran that actually stay in their own villages most of the time. An update of the expansion would probably involve rethinking them as support for their respective Koro strategies introduced in the redesign of BCOT, though some of them (like Jaller) already kind of fit in.
In their current state, the overarching theme of the Matoran shown here could be considered providing passive field-wide buffs that turn these small monsters into a formidable fighting force when Summoned en masse. With the Rahi-taming Matoran and the Lightstone cards, there are also some more gimmicky ideas here that I’m quite fond of, even though they may need some balancing fixes.
A sample Matoran deck can be found in the BCOR release.
