Doomsday

When Doomsday dies, if Doomsday was not sacrificed or exiled, put two evolve counters
on it. (this number increases by one for every
time Doomsday dies)
At the beginning of your upkeep, remove an evolve counter, when the last one is removed, return Doomsday to the battlefield with protection from colorless, or the color
of your choice.
