How it works
Declare Aurelia and Seluma as attackers. Aurelia triggers, causing you to untap all creatures you control and to get an additional combat phase after this one.
Activate Carrion Feeder by sacrificing Aurelia.
Deal combat damage using Seluma. Seluma triggers, returning Aurelia from your graveyard to the battlefield.
Repeat.
This elegant loop relies on Aurelia, the Warleader's triggered ability to continuously grant you additional combat phases and untap your board, creating the framework for infinite attacks. While Seluma, Light of Aysen handles the recursion by diving into your graveyard to pull Aurelia right back to the battlefield whenever Seluma connects for combat damage, Carrion Feeder acts as the essential sacrifice outlet to send Aurelia to that graveyard in the first place. By cycling Aurelia back and forth through the graveyard and onto the battlefield, you continuously trigger her untaps and Seluma's resurrections while stacking up infinite +1/+1 counters on the Feeder.
