Battle-Mad Ronin

The compulsion to attack is what makes the math interesting. Bushido rewards combat, and the must-attack clause guarantees combat happens, so the two abilities are designed to feed each other: every turn this swings as a 1/1 that jumps to a 3/3 the instant a blocker steps in. The tension is that the controller never chooses when it fights, only the opponent does, and the opponent gets to decide whether the bonus matters at all. Leave it unblocked and it pokes for one. Block it and it grows, but the defender picks the block, so they will only commit when they have something that survives or trades up after the boost resolves. That asymmetry is the cost baked into the rate: a 1/1 with this much combat upside should be an aggressive auto-include, except the bonus is a reactive pump rather than a way through, and Bushido triggers only after a block is declared, which means a savvy defender simply declines the fight. The result is a body that bluffs better than it brawls, threatening a trade it cannot force. It belongs to the early Samurai lineage that leaned on Bushido as the combat-keyword identity of red-white, where the "block or become blocked" trigger was the whole pitch and the drawbacks (here, the loss of attack control) were the lever designers pulled to price the bonus. As an aggressive-shell body, it needs a deck applying enough pressure that the opponent has to block, the only condition under which it stops being a glorified 1/1.
