Mishra, Eminent One + Urza, Lord High Artificer + Worldwalker Helm + Thopter Engineer

Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Thopter Engineer

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 ingenious loop is anchored by Mishra, Eminent One, who turns your noncreature artifacts into temporary 4/4 combat threats every turn. When Worldwalker Helm is targeted by Mishra, it enters the battlefield as a creature copy that doubles all your artifact token generation into extra Map tokens. Urza, Lord High Artificer acts as the engine's monetary heart, converting those freshly minted Maps into the blue mana needed to fuel Worldwalker Helm's ability to copy itself over and over. Meanwhile, Thopter Engineer provides an unassuming yet vital passive presence, granting all your artifact creatures haste so the newly copied Warforms can tap for mana immediately without summoning sickness slowing you down.
