Mishra, Eminent One + Urza, Lord High Artificer + Worldwalker Helm + Shang-Chi, Master of Kung Fu

Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Shang-Chi, Master of Kung Fu

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 turns your combat step into an engine of relentless multiplication by leveraging Mishra, Eminent One to animate Worldwalker Helm into a 4/4 artifact creature. Once Worldwalker Helm is animated, Shang-Chi, Master of Kung Fu lets you bypass summoning sickness to immediately tap it for a copied Helm token, which is further amplified by the Helm's own replacement effect to flood the board with Map tokens. Urza, Lord High Artificer acts as the engine's monetary heart, converting those extra Map tokens into blue mana to sustain the activation costs and eventually letting you cast every single spell from your library for free.
