Hell's Caretaker + Activated Sleeper + Yarus, Roar of the Old Gods

Hell's Caretaker

Activated Sleeper

Yarus, Roar of the Old Gods

How it works

1. During your upkeep, activate Hell's Caretaker by tapping and sacrificing it, returning Activated Sleeper from your graveyard to the battlefield as a copy of Hell's Caretaker.
2. Activate Activated Sleeper by tapping and sacrificing it, returning Hell's Caretaker from your graveyard to the battlefield.
3. Repeat.

This clever loop turns the graveyard into a revolving door by leveraging the original Hell's Caretaker to bring back Activated Sleeper as a fresh copy of the Caretaker itself. Once copied, this new instance immediately taps and sacrifices itself to bring the original Hell's Caretaker right back to the battlefield, setting up an endless cycle of resurrection. Meanwhile, Yarus, Roar of the Old Gods sits on the battlefield granting your creatures haste to ensure your army is always ready to strike, though its true brilliance here is the constant stream of deaths and enters-the-battlefield triggers generated by the loop.
