Mortuary + Ashes of the Abhorrent + Bolas's Citadel + Myr Scrapling

Mortuary

Ashes of the Abhorrent

Bolas's Citadel

Myr Scrapling

How it works

1. Activate Myr Scrapling by sacrificing it.
2. When Myr Scrapling dies, Mortuary and Ashes of the Abhorrent trigger.
3. Resolve the Mortuary trigger, putting Myr Scrapling from your graveyard onto the top of your library.
4. Resolve the Ashes of the Abhorrent trigger, causing you to gain 1 life
5. Resolve the Myr Scrapling ability.
6. Cast Myr Scrapling from the top of your library by paying 1 life.
7. Repeat.

This clever loop turns the lowliest artifact creature into an endless engine of life and growth. By leveraging Bolas's Citadel, you bypass traditional mana costs entirely, casting Myr Scrapling directly from the top of your library for a mere 1 life instead of its usual cost. As you sacrifice Myr Scrapling to its own ability, Mortuary immediately intercepts it from the graveyard to place it right back on top of your library, seamlessly resetting the Citadel's play condition. Meanwhile, Ashes of the Abhorrent sits quietly on the battlefield to harvest life from the constant cycle, netting you 1 life with every iteration to comfortably offset the life paid to the Citadel.
