Mortuary + Bloodflow Connoisseur + Ornithopter + Gwenom, Remorseless

Mortuary

Bloodflow Connoisseur

Ornithopter

Gwenom, Remorseless

How it works

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

This loop transforms a free, repeatable sacrifice outlet into an engine of endless growth by leaning on a clever interaction with the top of your library. While Bloodflow Connoisseur provides the muscle to consume your creatures for power, Mortuary ensures that any creature sent to the graveyard immediately returns to the top of your library instead of staying there. This is where Ornithopter plays its crucial role as free fuel, because its zero mana value allows you to recast it for zero life whenever Gwenom, Remorseless grants you permission to play from the top of your library. Together, these pieces create a perpetual motion machine that endlessly recycles the tiny artifact creature to pump up your sacrifice outlet and trigger any arrival or departure effects you desire.
