Mortuary + Atog + Memnite + Bolas's Citadel

Mortuary

Atog

Memnite

Bolas's Citadel

How it works

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

This brilliant loop turns your library into a recycling machine by anchoring it with Bolas's Citadel, which lets you freely cast spells directly from the top of your deck while paying life instead of mana. You begin by using Atog to sacrifice Memnite, feeding its hunger while triggering Mortuary to seamlessly place that same Memnite right back on top of your library. Because Memnite costs zero mana, Bolas's Citadel lets you replay it for free of life cost, instantly setting you up to repeat the cycle infinitely.
