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.
This loop is a masterclass in turning an opponent's own forces against them, perfectly orchestrated by Edea, Possessed Sorceress and Breath of Fury. You begin each combat by stealing an opposing creature with Edea, Possessed Sorceress, giving you an immediate aggressive body equipped with haste. When you enchant one of your own creatures with Breath of Fury and successfully connect with a player, its sacrifice trigger allows you to pivot the Aura onto that stolen creature. The magic truly happens because Edea, Possessed Sorceress watches over creatures you control but don't own; when that stolen sacrifice hits the graveyard, her second ability immediately resurrects it for its rightful owner while padding your hand with a fresh card. Meanwhile, Breath of Fury untaps your entire board and grants you an endless succession of additional combat phases to repeat the cycle infinitely.
