Mortuary + Wild Cantor + Bolas's Citadel + Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel

Mortuary

Wild Cantor

Bolas's Citadel

Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel

How it works

1. Activate Wild Cantor by sacrificing it.
2. When Wild Cantor dies, Mortuary and Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel trigger.
3. Resolve the Mortuary trigger, putting Wild Cantor from your graveyard onto the top of your library.
4. Resolve the Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel trigger, causing you to gain 1 life and target opponent to lose 1 life.
5. Cast Wild Cantor from the top of your library by paying 1 life.
6. Repeat.

This brilliant loop turns a humble sacrifice into a self-sustaining engine by letting you bypass conventional mana costs entirely. With Bolas's Citadel in play, you can continuously cast Wild Cantor straight from the top of your library, paying its mana value in life instead of mana while leveraging Mortuary to instantly recycle the creature right back where it started. Meanwhile, Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel watches the procession of constant deaths and enters, draining your opponents' life totals while fueling your own life cushion to keep the Citadel's payments going.
