Ulamarg, first to return

Trample, Vigilance
When Ulamarg enters the battlefield, all creatures
from all graveyards enter the battlefield under
your control with a +1/+1 counter and haste.
You get one reincarnation counter. If you have 9 reincarnation counters, you win the game,
and for the next 8 games that you play, you start
the game with all Undead Risen creatures on the battlefield at the start of the game.
