To pull off this devastating win, you first need to inflate your life total so that Storm Herd can flood the board with a massive swarm of Pegasus tokens. Once your army is assembled, you cast Eerie Interlude to temporarily exile all of those creatures, which simultaneously triggers Venerated Rotpriest for every single creature you control. Because Venerated Rotpriest watches for *any* creature you control becoming the target of a spell, this mass-targeting effect immediately funnels enough poison counters directly at your opponents to wipe them out of the game in one fell swoop.
