Mortuary + Goblin Bombardment + Bolas's Citadel + Fear of Lost Teeth

Mortuary

Goblin Bombardment

Bolas's Citadel

Fear of Lost Teeth

How it works

1. Activate Goblin Bombardment by sacrificing Fear of Lost Teeth.
2. When Fear of Lost Teeth dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Fear of Lost Teeth from your graveyard onto the top of your library.
4. Resolve the Fear of Lost Teeth trigger, causing you to gain 1 life and dealing 1 damage to any target.
5. Resolve the Goblin Bombardment ability.
6. Cast Fear of Lost Teeth from the top of your library by paying 1 life due to Bolas's Citadel.
7. Repeat.

This clever loop turns the graveyard into an extension of your hand, converting a modest rat into an endless engine of destruction. **Fear of Lost Teeth** serves as the expendable fuel, using its death trigger to both gain you life and ping targets, which conveniently offsets the life you pay to cast it. Meanwhile, **Mortuary** catches the creature as it hits the graveyard and neatly stacks it back on top of your library. From there, **Bolas's Citadel** lets you peer through the top of your deck and replay the creature straight from the library while paying life instead of mana. Finally, **Goblin Bombardment** provides the reliable sacrifice outlet to start the cycle all over again, infinitely repeating this sequence for endless damage, lifegain, and sacrifice triggers.
