text: Vicious Clown's ability checks the power of the other creature only at the moment it enters. If a creature enters with counters, those counters are included. If a creature's power is 2 or less when it enters but becomes greater than 2 while Vicious Clown's ability is still on the stack, Vicious Clown will still get +2/+0 until end of turn when its ability resolves.
