Mortuary + Grinding Station + Ornithopter + Gwenom, Remorseless

Mortuary

Grinding Station

Ornithopter

Gwenom, Remorseless

How it works

1. Activate Grinding Station by tapping it and sacrificing Ornithopter
2. When Ornithopter dies, Mortuary triggers, putting Ornithopter from your graveyard onto the top of your library.
3. Resolve the Grinding Station ability.
4. Cast Ornithopter from the top of your library by paying 0 life.
5. When Ornithopter enters, Grinding Station triggers, untapping Grinding Station.
6. Repeat.

This fascinating loop turns free artifact recasting into an infinite mill engine by leveraging Mortuary to constantly intercept your creatures in the graveyard and place them right back on top of your library. Gwenom, Remorseless is the key to playing out of that zone for free, letting you bypass traditional mana costs by paying life instead—a negligible cost when casting a zero-mana artifact like Ornithopter over and over. As the mechanical little centopter endlessly enters and leaves the battlefield, Grinding Station converts that perpetual motion into an untapped source of repeatable artifact sacrifices that mills your opponents out entirely.
