Venerated Rotpriest + Storm Herd + Scapegoat

Venerated Rotpriest

Storm Herd

Scapegoat

How it works

1. Cast Storm Herd by paying 8, creating a number of 1/1 Pegasus creature tokens equal to your life total.
2. Cast Scapegoat by paying and sacrificing a Pegasus, targeting every creature you control.
3. Venerated Rotpriest triggers for each creature targeted by Scapegoat.
4. Resolve the first trigger, causing an opponent to get a poison counter.
5. Repeat step 4 until an opponent loses the game due to having ten poison counters, then repeat for each other opponent.
