Companion — Each nonland card in your
starting deck is a creature card. (If this card is your chosen companion, you may cast it once from outside
the game.)
Each creature you control enters the battlefield
with up to one additional +1/+1 counter.
Whenever a creature you control evolves, adapts, mutates, or becomes monstrous, put a +1/+1
counter on that creature.
