How it works
Activate Yahenni by sacrificing Optimus Prime, Hero.
When Optimus Prime, Hero dies, its second ability triggers, returning it from your graveyard to the battlefield as Optimus Prime, Autobot Leader.
Activate Yahenni by sacrificing Optimus Prime, Autobot Leader.
When Optimus Prime, Autobot Leader dies, Luminous Broodmoth triggers, returning Optimus Prime from your graveyard to the battlefield as Optimus Prime, Hero with a flying counter on it.
Resolve both Yahenni abilities from steps 1 and 3.
Repeat.
This loop relies on an endless cycle of sacrifice and rebirth between Optimus Prime, Hero and Luminous Broodmoth, with Yahenni, Undying Partisan acting as the willing executioner. Because Optimus Prime features two distinct faces—Optimus Prime, Hero and Optimus Prime, Autobot Leader—each resurrection triggers the opposite side's death clause, allowing it to seamlessly alternate between its robot and vehicle forms. Luminous Broodmoth catches the vehicle side when it falls and returns it as the hero, while Yahenni, Undying Partisan safely consumes each iteration and grows steadily stronger from the endless casualties.
