Breath of Fury + Lathril, Blade of the Elves + The Fire Crystal

Breath of Fury

Lathril, Blade of the Elves

The Fire Crystal

How it works

1. Deal combat damage using the creature that has Breath of Fury attached and Lathril, triggering Breath of Fury and Lathril.
2. Resolve the Lathril trigger, creating at least one creature token.
3. Resolve the Breath of Fury trigger, causing you to sacrifice the creature it is attached to, then attach Breath of Fury to a creature token, then causing you to untap all creatures you control and to get an additional combat phase after this one.
4. Repeat each combat phase.

By enchanting Lathril, Blade of the Elves with Breath of Fury, you create an endless loop of extra combat phases; every time Lathril connects and triggers Breath of Fury, she sacrifices herself to move the Aura to one of the newly minted tokens while untapping your entire board. The Fire Crystal accelerates your strategy by giving all your creatures haste so they can attack immediately, while its passive cost reduction helps you manage the red mana needed to keep casting the Aura. Meanwhile, Lathril's combat damage keeps flooding the board with Elf tokens, giving you a fresh target to pass Breath of Fury onto in every single additional combat phase.
