This looping mechanism relies entirely on transforming your entire board into a massive dwarven workforce, thanks to Xenograft declaring every creature you control to be a Dwarf. Because Enduring Vitality grants every creature the ability to tap for any color of mana, tapping any creature kicks off Magda, Brazen Outlaw's ability to generate a Treasure token upon a Dwarf becoming tapped. That Treasure creation immediately triggers Stridehangar Automaton's replacement effect to sweeten the deal, churning out both a Treasure and an additional 1/1 Thopter token that also immediately counts as a Dwarf. With Hammer of Purphoros granting your creatures haste (and Enduring Vitality's vigilance keeping them ready), you can loop these taps infinitely to fuel your mana, flood the board with tokens, and eventually sacrifice five Treasures to Magda's own ability to fetch every artifact and Dragon from your library.
