Colony Ascendant

At the beginning of your end step, choose one: • Sacrifice a creature. If you do, create a token that’s a copy of that creature, except it’s a Zerg in addition to its other types and has +1/+1. • Sacrifice a Zerg creature. If you do, create two 0/1 black Changeling creature tokens. • Put a creep counter on target basic land you control.
