Mishra, Eminent One + Urza, Lord High Artificer + Worldwalker Helm + Barbarian Class

Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Barbarian Class

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 loop uses Mishra, Eminent One to turn Worldwalker Helm into a 4/4 copy called Mishra's Warform, triggering the Helm's replacement effect to double up on artifact token creation and spit out extra Map tokens. Urza, Lord High Artificer ties the whole engine together by converting those newly minted Maps into a steady stream of blue mana simply by tapping them. With this blue mana fueling Worldwalker Helm's copy ability, you can endlessly replicate the Warform to generate infinite mana, artifacts, and explores. Meanwhile, Barbarian Class sits quietly on the board providing extra utility, rounding out the combo for Commander, Legacy, Oathbreaker, and Vintage play.
