Mishra, Eminent One + Urza, Lord High Artificer + Worldwalker Helm + Hammer of Purphoros

Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Hammer of Purphoros

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 elegant loop turns your combat step into a self-sustaining engine by letting Mishra, Eminent One temporarily animate Worldwalker Helm into a 4/4 haste-granting creature while generating a bonus Map token. From there, Urza, Lord High Artificer steps in to convert those newly minted maps into a steady stream of blue mana simply by tapping them. You then use that mana to fuel Worldwalker Helm’s activated ability, copying the animated Helm over and over to multiply your output exponentially. While Hammer of Purphoros sits quietly in the background making sure your endless army enters the battlefield ready to act, the entire engine spins out of control until you have total dominance over your library and board state.
