Mortuary + Krark-Clan Ironworks + Summoning Materia

Mortuary

Krark-Clan Ironworks

Summoning Materia

How it works

1. Activate Krark-Clan Ironworks by sacrificing the nontoken creature, adding CC.
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Cast the creature by paying its mana cost.
4. Repeat.

This loop transforms your battlefield and graveyard into a self-sustaining engine by letting you repeatedly sacrifice a creature to Krark-Clan Ironworks for colorless mana. Mortuary ensures that every time that creature meets its end, it doesn't stay in the graveyard—instead, it smoothly returns directly to the top of your library. Thanks to Summoning Materia granting you the ability to cast creature spells straight from the top of your library while you look ahead, you can immediately redeploy the exact same creature using the mana you just generated.
