Edea, Possessed Sorceress, and Breath of Fury

Prerequisites

• Edea, Possessed Sorceress on the battlefield

2. Deal combat damage to an opponent using the creature that has Breath of Fury attached
3. Breath of Fury triggers, causing you to sacrifice the creature it is attached to, and then attach Breath of Fury to the creature you gained control of in step 1
4. Then, untap all creatures you control and get an additional combat phase after this one
5. If the creature sacrificed in step 3 was nontoken and owned by an opponent, Edea's second ability triggers, returning the creature from its owner's graveyard to the battlefield under their control and causing you to draw a card
