Duel for Dominance

Instant • Mana cost: {1}{G} • Innistrad Remastered • Common

Coven — Choose target creature you control and target creature you don't control. If you control three or more creatures with different powers, put a +1/+1 counter on the chosen creature you control. Then the chosen creatures fight each other. (Each deals damage equal to its power to the other.)
