By turning every creature you control into a Dwarf via Maskwood Nexus, you open the door to turning standard actions into a cascade of value with Magda, Brazen Outlaw. Cryptolith Rite grants those creatures the ability to tap for mana, and thanks to Thousand-Year Elixir, they can do so the moment they enter the battlefield without waiting for summoning sickness. Whenever you tap one of these creatures, Magda triggers to generate a Treasure token, which Stridehangar Automaton gleefully multiplies by adding an extra 1/1 Thopter token to the mix. Because those Thopters and Shapeshifter tokens also count as Dwarves through Maskwood Nexus, you can continuously tap your growing army to generate infinite mana, artifacts, and Treasures—ultimately letting you sacrifice five Treasures to Magda's own ability and pull every artifact and Dragon right out of your library.
