This loop turns your graveyard into a perpetual motion machine by leveraging Slimefoot and Squee's resurrection ability alongside Umbral Collar Zealot's sacrifice outlet. Once you tap Selvala, Heart of the Wilds for a massive injection of mana, you can feed her and Slimefoot and Squee to the Zealot, sending them both to the graveyard so they can be immediately brought back. Slimefoot and Squee kindly replaces its own cost by spawning a Saproling token upon entering the battlefield, which can then be sacrificed to feed the cycle or fuel further activations. Meanwhile, Anger rests quietly in your graveyard, granting your entire team haste so you can execute this explosive sequence the moment creatures hit the board.
