Mortuary + Aetherflux Reservoir + Goblin Bombardment + Bolas's Citadel

Mortuary

Aetherflux Reservoir

Goblin Bombardment

Bolas's Citadel

How it works

1. Activate Goblin Bombardment by sacrificing a creature
2. When the creature dies, Mortuary triggers, putting the creature from your graveyard onto the top of your library.
3. Resolve the Goblin Bombardment ability.
4. Cast the creature from the top of your library by paying X life, where X is the creature's mana value.
5. Aetherflux Reservoir triggers, causing you to gain 1 life for each spell you've cast this turn.
6. Repeat.

This ingenious loop turns your library into an endless recycling engine fueled by Bolas's Citadel, which lets you cast creatures directly from the top of your library by paying life instead of their mana costs. Whenever you sacrifice a creature to Goblin Bombardment, Mortuary catches it on its way to the graveyard and neatly stacks it right back on top of your library to be cast all over again. As this endless cycle spins, Aetherflux Reservoir effortlessly outpaces the life you pay to Bolas's Citadel by stacking up massive life gain with every repeated cast, eventually converting your boundless storm count into a lethal 50 damage blast to wipe out the opposition.
