This elegant loop relies on Priest of Titania generating a surplus of green mana—supported by having enough other Elves on the battlefield—to repeatedly fund Temur Sabertooth’s bounce ability. By paying to return the Priest to your hand and then recasting it, you continuously reset its enters-the-battlefield trigger for infinite storm count, creature entries, and mana. Meanwhile, Akroma's Memorial quietly sits on the battlefield, blanketing your entire army (including the bouncing Priest) with a devastating suite of evergreen keywords like flying, haste, and protection from black and red to ensure your opponents can neither easily block nor interact with your assembling pieces.
