Toshiro Umezawa

Legendary Creature — Human Samurai

Bushido 1 (Whenever this creature blocks or becomes blocked, it gets +1/+1 until end of turn.) Whenever a creature an opponent controls dies, you may cast target instant card from your graveyard. If that spell would be put into a graveyard, exile it instead.

Though only looking out for himself, Toshiro ended up saving all of Kamigawa.
