Mortuary + Memnite + Yahenni, Undying Partisan + Gwenom, Remorseless

Mortuary

Memnite

Yahenni, Undying Partisan

Gwenom, Remorseless

How it works

1. Activate Yahenni by sacrificing Memnite
2. When Memnite dies, Mortuary triggers, putting Memnite from your graveyard onto the top of your library.
3. Resolve the Yahenni ability.
4. Cast Memnite from the top of your library by paying 0 life.
5. Repeat.

This clever loop transforms free artifact creatures into an engine of endless triggers by exploiting the unique card-flow properties of your library. When you feed Memnite to Yahenni, Undying Partisan's sacrifice ability, Mortuary immediately catches the creature on its way to the graveyard and stacks it right back on top of your library. From there, Gwenom, Remorseless steps in to let you play that top card directly, completely bypassing mana costs with life payments that cost you a mere zero life for Memnite. Together, these pieces create an unstoppable cycle that racks up infinite sacrifices, deaths, and storm count without ever running out of fuel.
