Magda, Brazen Outlaw + Stridehangar Automaton + Arcane Adaptation + Citanul Hierophants + Gimli's Reckless Might

Magda, Brazen Outlaw

Stridehangar Automaton

Arcane Adaptation

Citanul Hierophants

Gimli's Reckless Might

How it works

1. Activate a creature by tapping it.
2. Magda triggers, as the creature is a Dwarf due to Arcane Adaptation, creating a 1/1 Thopter artifact creature token and a Treasure token due to Stridehangar Automaton.
3. Repeat.

This engine transforms any creature into a one-man manufacturing plant by rewriting the fundamental biology of your battlefield with Arcane Adaptation naming Dwarves, letting every creature tap for green mana thanks to Citanul Hierophants, and granting immediate action via Gimli's Reckless Might. When you tap a creature for mana, Magda, Brazen Outlaw sees a Dwarf becoming tapped and triggers, which Stridehangar Automaton supercharges by churning out both a Treasure and a flying Thopter for every single token creation event. Because those new Thopters are also treated as Dwarves by Arcane Adaptation, and because Citanul Hierophants gives them the tap ability right away, you can chain the tapping indefinitely to generate infinite mana, tokens, and sacrifice fodder. Once your hoard is infinitely large, you can simply cash in five Treasures to Magda's ability to tutor every artifact and a subset of dragons directly from your library onto the battlefield.
