Jaws of Defeat + Viscid Lemures

Jaws of Defeat

Viscid Lemures

How it works

1. Cast Viscid Lemures by paying 4
2. When Viscid Lemures enters the battlefield, Jaws of Defeat triggers.
3. Holding priority, activate Viscid Lemures by paying 0, giving it -1/-0 and swampwalk until end of turn.
4. Repeat step 3 an arbitrarily large number of times.
5. Resolve the Jaws of Defeat trigger, causing an opponent to lose life equal to the difference between Viscid Lemures' power and toughness.
