Bushido

Bushido is a triggered ability that makes creatures bigger if they block or are blocked. In Japanese, bushido means "Way of the Warrior", which ties in well with the Japanese themed Kamigawa block wherein all cards with bushido are printed. All creature cards with bushido have the creature type "Samurai".

From the Comprehensive Rules

• 502.38. Bushido
  • 502.38a Bushido is a triggered ability. “Bushido N” means “Whenever this creature blocks or becomes blocked, it gets +N/+N until end of turn.” (See rule 309, “Declare Blockers Step.”)
  • 502.38b The bushido bonus is calculated only once per combat, when the triggered ability resolves. Adding or removing blockers later in combat won’t change the bonus.
  • 502.38c If a creature has multiple instances of bushido, each triggers separately.

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.
