This loop turns any routine tap-activation into an engine of creation by using Xenograft to redefine every creature you control as a Dwarf. With that type-shifting in place, tapping a creature triggers Magda, Brazen Outlaw to demand a Treasure, which Stridehangar Automaton happily supersizes by appending an extra flying Thopter to the mix. A Realm Reborn steps in to fund your tapping costs on demand with any-color mana, while Krang, Utrom Warlord grants your newly minted mechanical swarm indestructible resilience, flying, trample, and haste. Once you have generated infinite Treasures and artifact tokens through this tapped-creature loop, you can crack Magda's five-Treasure sacrifice ability repeatedly to tutor every single artifact and a subset of creatures directly from your library onto the battlefield.
