Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Samut, Voice of Dissent

How it works

1. At the beginning of your combat phase, Mishra triggers, creating a token copy of Worldwalker Helm that is a 4/4 Construct artifact creature with haste named Mishra's Warform, and a Map token.
2. Activate Urza's first ability by tapping a Map, adding .
3. Activate Mishra's Warform by paying 1 and tapping it, creating a token copy of it and a Map token for each Mishra's Warform and/or Worldwalker Helm you control.
4. Activate Urza's first ability twice by tapping two Maps, adding .
5. Repeat from step 3.

This fascinating loop spins out of control by turning Mishra, Eminent One into a factory for copying artifacts during your combat phase. The key enabler is Worldwalker Helm, which multiplies every artifact token you create—including the animated Mishra's Warform copies and extra Map tokens—into an escalating flood of treasures. Meanwhile, Urza, Lord High Artificer acts as the engine's financial heart, effortlessly converting all those newly minted Map tokens into a massive reservoir of blue mana. Finally, Samut, Voice of Dissent rounds out the crew; while her activated ability isn't strictly necessary for the core loop, her presence ties the board together with haste, ensuring your rapidly multiplying army is ready to act immediately.
