Breath of Fury + Lavaleaper + Drider

Breath of Fury

Lavaleaper

Drider

How it works

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

This loop relies on Lavaleaper to grant haste to all your creatures so they can immediately attack in the freshly generated combat phases. You start by using Drider and the creature enchanted by Breath of Fury to deal combat damage to a player, which triggers Breath of Fury to sacrifice its host, attach to the newly created Spider token, untap your team, and grant you an extra combat phase. Because Drider also generates a fresh 2/1 Spider token with menace and reach on each successful strike, you always have a fresh target ready to wear Breath of Fury and keep the relentless chain of attacks going indefinitely.
