Overkill + Jaws of Defeat

Overkill

Jaws of Defeat

How it works

1. Cause any creature to enter the battlefield under your control, triggering Jaws of Defeat.
2. Holding priority, cast Overkill by paying 2, giving the creature that entered -0/-9999 until end of turn.
3. The creature dies as a state-based action due to having less than 0 toughness.
4. Resolve the Jaws of Defeat trigger, causing target opponent to lose life equal to the difference between the creature's power and toughness, using its last known information.
