Mortuary + Bolas's Citadel + Bartolomé del Presidio + Crookshank Kobolds

Mortuary

Bolas's Citadel

Bartolomé del Presidio

Crookshank Kobolds

How it works

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

This clever loop transforms free mana-value-zero creatures into an endless cycle of sacrifice and rebirth. With Bolas's Citadel providing the crucial ability to play spells directly from the top of your library while bypassing mana costs with life, you can repeatedly cast Crookshank Kobolds after Bartolomé del Presidio sends it to the graveyard. Every time the Kobolds hit the graveyard, Mortuary quietly ensures the creature goes straight back to the top of your library, perfectly positioned for the Citadel to cast it again for zero life.
