Viktor, the Howling King

Facedown creatures you control are 3/3 green werewolves.
Whenever a werewolf you control transforms put X +1/+1 counters on it, where X is the number of +1/+1 counters it has.
{b}{r}{g}: put a +1/+1 counter on each creature you control.
{1}{b}{g}{r}: transform all other creatures you control.
