This engine relies on Priest of Titania generating an excess of green mana with every tap, which Temur Sabertooth then harnesses to repeatedly bounce and recast the Elf, netting a surplus of mana and storm count each iteration. Hammer of Purphoros quietly ensures that the Priest—and any other creatures you loop—gain haste the moment they re-enter the battlefield, allowing you to tap them for mana immediately without summoning sickness slowing you down. Together, this trio turns a simple mana-dork into an unstoppable, self-sustaining loop that floods the board and sets off endless entry triggers.
