This remarkable engine transforms the land-counting trigger of Emeritus of Abundance // Regrowth into an infinite loop of recursion and mana generation. By fueling Pyromancer Ascension with repeated spellcasts, you gain the ability to copy spells and safely recur every resource in your graveyard. Brass's Bounty provides the explosive treasure economy required to keep the mana flowing, while Woe Strider acts as a reliable sacrifice outlet to continuously clear your board and manipulate your library via scry. Finally, Regrowth (alongside its other printing) acts as the ultimate glue, pulling everything back from the graveyard just in time to do it all over again.
