Mortuary + Bolas's Citadel + Tinder Wall + Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel

Mortuary

Bolas's Citadel

Tinder Wall

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

How it works

1. Activate Tinder Wall by sacrificing it.
2. When Tinder Wall dies, Mortuary and Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel trigger.
3. Resolve the Mortuary trigger, putting Tinder Wall 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 Tinder Wall from the top of your library by paying 1 life.
6. Repeat.

This clever loop turns simple mana generation into a devastating cycle by using Bolas's Citadel to cast spells directly from the top of your library while paying life instead of mana. When you sacrifice Tinder Wall for red mana, Mortuary catches it on its way to the graveyard and immediately places it right back onto the top of your library. Meanwhile, Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel watches the creature die and drains your opponent's life total while netting you life to offset the cost of recasting the wall.
