Kuro's Taken

Bushido on a 1/1 is mostly a defensive bluff: it deters a marginal attacker and trades up in a pinch, but the Bushido bump alone folds to any removal that doesn't go through combat. The regeneration shield rewrites that math during the combat step itself. Block, take the +1/+1 up to a 2/2, then pay the regeneration cost to survive lethal damage and walk away having eaten a larger creature for free. The two abilities are timed to reinforce each other inside a single turn, and that's the whole point of the design: the temporary size bump wins the trade, the regeneration keeps the body around to do it again next turn. The cost is the catch. Holding up the regeneration mana every turn taxes the rest of your hand, so the Rat is really a mana sink that asks you to choose between developing and defending. It reads as a humble combat creature, but the construction is closer to an attrition tool: a recurring blocker that bleeds an aggressor's board one swing at a time, provided you can keep feeding it.
