Edea, Possessed Sorceress + Breath of Fury Combo

Edea and Breath of Fury on the battlefield.

An opponent controls a nontoken creature.

Breath of Fury is attached to another creature you control that does not have summoning sickness. An opponent cannot block creatures you control.

At the beginning of your combat phase, Edea's first ability triggers, causing you to gain control of a creature an opponent controls and then untap that creature and give it haste until end of turn.

Deal combat damage to an opponent using the creature that has Breath of Fury attached.

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. Then, untap all creatures you control and get an additional combat phase after this one.

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.

Repeat each combat phase.
