Maskwood Nexus is the crucial glue of this engine, quietly turning every creature you control into a Dwarf, Thopter, and every other creature type so that Stridehangar Automaton and Magda, Brazen Outlaw recognize every single activation. Thanks to A Realm Reborn, those creatures can tap directly for mana, and every time a creature is tapped, Magda triggers to generate a Treasure token. Stridehangar Automaton then supercharges this production, replacing each artifact token with both the intended Treasure and an additional 1/1 Thopter artifact creature token. Meanwhile, Barbarian Class provides haste so your newly created army can immediately join the fray, letting you loop the tapping process to churn out boundless resources until you can cash in five Treasures with Magda to tutor up any artifact or Dragon from your library.
