This potent mana-positive loop centers around Pyromancer Ascension, which duplicates your key spells once it accumulates two quest counters, while Brass's Bounty provides an overwhelming surge of Treasure tokens to fund your recursive engine. By using Regrowth to continually pull your spent resources and threats back to your hand, you fuel a continuous cycle of casting and recasting. Thermopod acts as a crucial sacrifice outlet that feeds your mana pool and recycles creatures, working in tandem with Emeritus of Abundance (and its prepared side Regrowth) to ensure you always have access to the pieces you need to keep the combo spinning infinitely.
