If Serrated Biskelion leaves the battlefield before its ability resolves, you’ll still put a -1/-1 counter on the targeted creature. If the target leaves the battlefield or otherwise becomes an illegal target before the ability resolves, the ability doesn’t resolve and you won’t put a -1/-1 counter on Serrated Biskelion.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
: Put a -1/-1 counter on Serrated Biskelion and a -1/-1 counter on target creature.
