Mishra, Eminent One + Urza, Lord High Artificer + Worldwalker Helm + Tannuk, Steadfast Second

Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Tannuk, Steadfast Second

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 clever setup revolves around Mishra, Eminent One turning Worldwalker Helm into a 4/4 Construct artifact creature copy called Mishra's Warform each combat, while Tannuk, Steadfast Second ensures your team is ready for action with its passive haste grant. Worldwalker Helm’s replacement effect turns every token creation into a cascading engine that churns out an extra Map token alongside each new copy. As these tokens flood the board, Urza, Lord High Artificer steps in to convert your rapidly multiplying artifacts into a limitless supply of blue mana by simply tapping them. Ultimately, this engine generates infinite resources to let you churn through your entire library and cast every spell you own for the win.
