Aurelia, the Warleader + Seluma, Light of Aysen + Yahenni, Undying Partisan

Aurelia, the Warleader

Seluma, Light of Aysen

Yahenni, Undying Partisan

How it works

1. 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.
2. Activate Yahenni by sacrificing Aurelia.
3. Deal combat damage using Seluma. Seluma triggers, returning Aurelia from your graveyard to the battlefield.
4. Repeat.

This loop leverages Seluma, Light of Aysen as your commander to continuously recycle your army, utilizing her ability to pull fallen Angels straight from the graveyard to the battlefield whenever she connects. To make this an infinite engine, Aurelia, the Warleader provides the vital extra combat phases and untaps your board on her first attack, while Yahenni, Undying Partisan acts as the necessary sacrifice outlet to send Aurelia back to the graveyard between phases. By sacrificing Aurelia mid-combat and bringing her right back with Seluma's combat damage trigger, you generate endless combat steps, creature deaths, and enters-the-battlefield triggers.
