At the beginning of your upkeep, put three +1/+1 counters on target creature you control and three +1/+1 counters on target creature an opponent controls.
You choose two targets for Evolutionary Escalationâ€™s ability as itâ€™s put onto the stack. No player may cast spells or activate abilities during your turn before this happens.
If there arenâ€™t two legal targets for Evolutionary Escalationâ€™s ability as itâ€™s put onto the stack, itâ€™s taken off the stack and no creature gets +1/+1 counters.
If one target becomes illegal before Evolutionary Escalationâ€™s ability resolves, youâ€™ll put three +1/+1 counters on the target thatâ€™s still legal.
