Mortuary + Yahenni, Undying Partisan + Fear of Lost Teeth + Gwenom, Remorseless

Mortuary

Yahenni, Undying Partisan

Fear of Lost Teeth

Gwenom, Remorseless

How it works

1. Activate Yahenni by sacrificing Fear of Lost Teeth.
2. When Fear of Lost Teeth dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Fear of Lost Teeth from your graveyard onto the top of your library.
4. Resolve the Fear of Lost Teeth trigger, causing you to gain 1 life and dealing 1 damage to any target
5. Resolve the Yahenni ability.
6. Cast Fear of Lost Teeth from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This clever setup uses Mortuary to instantly recycle any creature that hits your graveyard back to the top of your library, creating a perpetual motion machine of sacrifice. Yahenni, Undying Partisan acts as your reliable sacrifice outlet, growing larger while providing a way to put creatures into the graveyard on demand. Meanwhile, Fear of Lost Teeth serves as the perfect ammunition, dealing damage and gaining life whenever it dies before getting tucked back into your library. Finally, Gwenom, Remorseless completes the loop by letting you play that freshly tucked creature directly off the top of your library, trading a tiny bit of life to recast it and do it all over again.
