This ingenious engine begins by turning your entire board into a unified swarm: Maskwood Nexus makes every creature you control every creature type, granting them the Dwarf subtype for Magda, Brazen Outlaw, the Thopter subtype for Stridehangar Automaton, and turning them all into mana dorks via Citanul Hierophants. Because Samut, Tyrant Smasher gives your creatures haste, they can tap the moment they enter the battlefield to produce green mana. Tapping any creature to pay its own mana ability simultaneously triggers Magda, Brazen Outlaw to generate a Treasure token, which Stridehangar Automaton replaces by adding an extra 1/1 Thopter artifact creature token alongside the Treasure. That newly created Thopter also immediately enters with haste and its own mana ability ready to tap, feeding the loop infinitely and letting you cash in your endless Treasures to tutor every artifact and Dragon straight from your library.
