Roalesk, Apex Hybrid
Legendary Creature — Human Mutant, {2}{G}{G}{U}
Oracle Text
Flying, trample
When Roalesk enters, put two +1/+1 counters on another target creature you control.
When Roalesk dies, proliferate, then proliferate again. (Choose any number of permanents and/or players, then give each another counter of each kind already there. Then do it again.)
