Mortuary + Daxos, Blessed by the Sun + Bolas's Citadel + Goblin Firestarter

Mortuary

Daxos, Blessed by the Sun

Bolas's Citadel

Goblin Firestarter

How it works

1. Activate Goblin Firestarter by sacrificing it.
2. When Goblin Firestarter dies, Mortuary and Daxos trigger.
3. Resolve the Mortuary trigger, putting Goblin Firestarter from your graveyard onto the top of your library.
4. Resolve the Daxos trigger, causing you to gain 1 life
5. Resolve the Goblin Firestarter ability.
6. Cast Goblin Firestarter from the top of your library by paying 1 life.
7. When Goblin Firestarter enters, Daxos triggers, causing you to gain 1 life.
8. Repeat.

This intricate loop transforms a humble Goblin Firestarter into a lethal weapon by turning its self-sacrifice into a self-sustaining cycle. Bolas's Citadel acts as the engine, allowing you to bypass mana costs entirely and cast the goblin directly from the top of your library by paying life instead. Meanwhile, Mortuary ensures the creature never stays in the graveyard, neatly placing it right back on top of your library every time it dies. Finally, Daxos, Blessed by the Sun keeps your life total safely insulated against the Citadel's toll, converting every single entry and exit into a net-neutral or positive life swing while you steadily burn your opponents out.
