Breath of Fury + Fires of Yavimaya + Koma, World-Eater

Breath of Fury

Fires of Yavimaya

Koma, World-Eater

How it works

1. Deal combat damage using the creature that has Breath of Fury attached and Koma, triggering Breath of Fury and Koma.
2. Resolve the Koma trigger, creating four creature tokens.
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.

This ingenious loop lets Koma, World-Eater single-handedly fuel an endless stream of assault phases by leaning on the global haste granted by Fires of Yavimaya. When Koma crashes in and deals combat damage to an opponent, its trigger spawns a flurry of Koma's Coil tokens, while Breath of Fury simultaneously demands you sacrifice the creature it enchants to jump to a fresh creature token. Because Fires of Yavimaya ensures your newly minted serpents are immediately ready to rumble, you can continuously attach Breath of Fury to a fresh token, untap your entire board, and ride infinite combat phases straight to victory.
