Mortuary + Krark-Clan Ironworks + Memnite + Bolas's Citadel

Mortuary

Krark-Clan Ironworks

Memnite

Bolas's Citadel

How it works

1. Activate Krark-Clan Ironworks by sacrificing Memnite
2. When Memnite dies, Mortuary triggers, putting Memnite from your graveyard onto the top of your library.
3. Cast Memnite from the top of your library by paying 0 life.
4. Repeat.

This clever loop turns zero-mana artifacts into a bottomless well of resources by leaning on Bolas's Citadel to bypass mana costs with life payments instead. When you sacrifice Memnite to Krark-Clan Ironworks, you generate a burst of colorless mana while setting up a seamless recursion engine. Mortuary steps in to catch Memnite as it hits the graveyard, immediately placing it back on top of your library where Bolas's Citadel lets you cast it again for free. Repeating this cycle yields infinite colorless mana, death triggers, and storm count without ever running out of fodder.
