Adan, The First Lich

First Strike, Deathtouch, Trample
If Adan, The First Lich would die, instead
exile it with one grave counter on it.
At the beginning of your upkeep, if Adan is
exiled with a grave counter on it, remove a
grave counter from it. Then if Adan has no
grave counters on it, return it to the battlefield.
