Apocalypse, The First

Trample, indestructible

Other Mutants you control enter the battlefield with an additional evolution counter on them.

At the beginning of your end step, choose a creature you control. If it has the fewest counters among creatures you control, sacrifice it. Put that many evolution counters plus one on another target Mutant you control.

Mutants you control with three or more evolution counters get +2/+2 and have menace.
