Breath of Fury + Bladewing, Deathless Tyrant + The Fire Crystal

Breath of Fury

Bladewing, Deathless Tyrant

The Fire Crystal

How it works

1. Deal combat damage using the creature that has Breath of Fury attached and Bladewing, triggering Breath of Fury and Bladewing.
2. Resolve the Bladewing 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.

This aggressive looping engine relies on Bladewing, Deathless Tyrant connecting with an opponent to flood your board with Zombie Knight tokens, which are instantly granted haste by The Fire Crystal. By enchanting one of those attackers with Breath of Fury, dealing combat damage triggers both cards simultaneously: Bladewing bolsters your token army while Breath of Fury forces a sacrifice, hops onto a fresh token, and untaps all your creatures to grant an extra combat phase. Because The Fire Crystal also discounts your red spells, you can even leverage its mana-cost reduction if you weave in extra red magic, though the core combo simply repeats this endless chain of extra combats and sacrifices forever.
