Nasus

Respawn 3 (If this creature would die, exile it instead with three time counter on it. At the beginning of your upkeep, remove a time counter from it. When you remove the last, this creature return to the battlefield. Keep all counters on it.)
Whenever a creature you don't control dies, put a +1/+1 counter on Nasus.
At the beginning of your upkeep, each opponent create a 1/1 white Minion creature token.
