Mortuary + Bolas's Citadel + Myr Scrapling + Funeral Room // Awakening Hall

Mortuary

Bolas's Citadel

Myr Scrapling

Funeral Room // Awakening Hall

How it works

1. Activate Myr Scrapling by sacrificing it.
2. When Myr Scrapling dies, Mortuary and Funeral Room // Awakening Hall trigger.
3. Resolve the Mortuary trigger, putting Myr Scrapling from your graveyard onto the top of your library.
4. Resolve the Funeral Room // Awakening Hall trigger, causing you to gain 1 life and each opponent to lose 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 brilliant loop turns a humble Myr Scrapling into an endless engine of sacrifice by leveraging Mortuary to constantly recycle it back to the top of your library. Bolas's Citadel plays the crucial supporting role of granting permission to cast that repeating spell right off the library, substituting its mana cost with a small payment of life. Meanwhile, the unlocked Awakening Hall side of Funeral Room // Awakening Hall gently offsets that life cost by draining your opponents and healing you with every single death trigger.
