Mortuary + Megatog + Ornithopter + Gwenom, Remorseless

Mortuary

Megatog

Ornithopter

Gwenom, Remorseless

How it works

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

This clever loop turns zero-mana artifacts into a bottomless engine of growth and triggers by leveraging Gwenom, Remorseless to peer into the future and bypass mana costs with life. With Gwenom's attack trigger active, you can repeatedly feed Ornithopter to Megatog's sacrifice ability to pump up your massive juggernaut while generating an endless stream of death triggers. Whenever the tiny flyer hits the graveyard, Mortuary immediately catches it and slips it right back onto the top of your library. From there, Gwenom lets you recast the free Ornithopter over and over, letting you trade zero life to fuel infinite storm count, sacrifices, and a devastatingly large Megatog.
