Doomgape + Serra Avatar + Vizkopa Guildmage

Doomgape

Serra Avatar

Vizkopa Guildmage

How it works

1. At the beginning of your upkeep, Doomgape triggers.
2. Holding priority, activate Vizkopa Guildmage's second ability by paying 1.
3. Resolve the Doomgape trigger, causing you to sacrifice Serra Avatar and gain life equal to its toughness.
4. Vizkopa Guildmage triggers, causing each opponent to lose life equal to the life you gained.

This clever loop turns Doomgape's mandatory upkeep sacrifice into a devastating life-draining engine, relying on Serra Avatar's unique knack for recycling itself straight back into your library to fuel the fire turn after turn. Because Serra Avatar's power and toughness dynamically match your soaring life total, every iteration of this sacrifice yields an astronomical amount of life. Vizkopa Guildmage ties the whole operation together by converting that massive lifegain into direct, lethal damage for your opponents, closing out games in formats like Commander and Legacy.
