Mortuary + Viscera Seer + Tarpan + Gwenom, Remorseless

Mortuary

Viscera Seer

Tarpan

Gwenom, Remorseless

How it works

1. Activate Viscera Seer by sacrificing Tarpan.
2. When Tarpan dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Tarpan from your graveyard onto the top of your library.
4. Resolve the Tarpan trigger, causing you to gain 1 life
5. Resolve the Viscera Seer ability.
6. Cast Tarpan from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This elegant loop uses Viscera Seer as your sacrifice outlet to repeatedly send Tarpan to the graveyard, where Mortuary immediately intercepts it and tucks it right back onto the top of your library. Meanwhile, Gwenom, Remorseless provides the crucial alternative casting permission that lets you bypass traditional mana costs by paying life instead, perfectly fueling the engine to keep recasting Tarpan over and over. Since Tarpan's own death trigger gains you 1 life each iteration, it effortlessly offsets the life you pay to Gwenom, allowing you to generate an infinite storm count, endless sacrifices, and infinite scry 1 triggers with Viscera Seer.
