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.
Survival is a constant competition from which both sides can benefit.

If one target becomes illegal before Evolutionary Escalation's ability resolves, you'll put three +1/+1 counters on the target that's still legal.

If there aren't two legal targets for Evolutionary Escalation's ability as it's put onto the stack, it's taken off the stack and no creature gets +1/+1 counters.
