By setting Leyline of Transformation to name "Dwarf" before the game begins, every creature you control instantly counts as a Dwarf to fuel Magda, Brazen Outlaw's trigger whenever it taps. Thanks to A Realm Reborn, those same creatures gain the ability to tap for any color of mana, while Stridehangar Automaton ensures that every single Treasure token generated also triggers the creation of an extra 1/1 Thopter artifact creature token. Meanwhile, The Fire Crystal discounts your red spells, gives your new army haste so they can tap immediately, and provides a powerful copying effect if you need it. By continually tapping your creatures for mana, you spin an endless engine that floods the board with infinite Treasures and Thopters, allowing Magda to tutor every single artifact and Dragon straight out of your library.
