Honed Blades

Whenever a creature you control with bushido
deals combat damage to a player, they create a
blood token. Then if defending player has five or
more blood tokens, they sacrifice all blood tokens
they control and lose 1 life for each blood token
they sacrificed this turn. (A Blood token is a
colorless artifact token with "{1}, {t}, Discard a card,
Sacrifice this artifact: Draw a card.")
Equipped creatures you control have bushido 1.
