Bushido

Bushido is a triggered keyword ability that makes creatures bigger if they block or are blocked.

History
Bushido appeared in the Kamigawa block as an ability associated with the Samurai creature type, and the ability has only appeared on Samurai creature cards, with the exception of Greater Morphling from the silver-bordered (and therefore tournament-illegal) Unhinged set. Some cards from other sets (such as Chub Toad from Ice Age) have similar abilities, but do not use the bushido keyword.

Bushido, renamed Chivalry, was considered as a knight mechanic for Throne of Eldraine.

Rulings

 * The bushido ability doesn't care how many creatures are blocking the creature with bushido. For example, a creature with bushido 1 that's blocked by three creatures still gets only +1/+1.
