How it works
Deal combat damage using the creature that has Breath of Fury attached and Tana, triggering Breath of Fury and Tana.
Resolve the Tana trigger, creating at least one creature token.
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.
Repeat each combat phase.
This brilliant loop relies on Tana, the Bloodsower dealing combat damage to churn out an army of Saproling tokens, which are instantly granted haste by Rising of the Day so they never waste a moment. Breath of Fury ties the whole engine together by demanding you sacrifice its host when combat damage lands, only to instantly reattach itself to one of those newly minted tokens. Because Rising of the Day and Breath of Fury's untap effect ensure your entire board stands ready again for the additional combat phase generated, you can endlessly chain attacks and sacrifices to bury your opponents in infinite damage and tokens.
