Yojimbo, Aeon for Hire

Bushido 2 (When this blocks or becomes blocked, it
gets +2/+2 until end of turn.)
{x}{x}: Yojimbo gets +X/+0 until end of turn. If
X is 2 or more, create Daigoro, a legendary 3/3
red Hound creature token with haste. Exile it at
the beginning of the next end step. If X is 4 or
more, target opponent sacrifices a creature at
random.
