MTG >Combos >Sword of Feast and Famine +Felhide Spiritbinder +Aurelia, the Warleader +

Equip Aurelia with Sword of Feast and Famine, then attack with all creatures. Aurelia's ability will trigger, creating an additional combat phase. When Aurelia deals combat damage to the opponent, untap all your lands. When untapping your creatures, pay 1R to activate Fellhide Spiritbinder's ability, copying Aurelia. With the Legends Rule, sacrifice the first Aurelia. Repeat the process for infinite mana and infinite combat.
