Tetsuo, Revered Ancestor

Eminence - As long as Tetsuo is in the command zone or on the battlefield, anytime a samurai you control dies create a 1/1 white Samurai Spirit token.
Other Samurai you control have Undying (When this creature dies, if it had no +1/+1 counters on it, return it to the battlefield under its owner's control
with a +1/+1 counter on it.)
