Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Mass Hysteria

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 engine relies on the synergy between Mishra, Eminent One and Worldwalker Helm to exponentially multiply your battlefield presence, all while Mass Hysteria ensures your newly minted tokens can tap the moment they enter. Urza, Lord High Artificer acts as the engine's core economic engine, turning your swelling sea of artifacts into an endless reservoir of blue mana. By using Worldwalker Helm's copy ability—fueled by the mana Urza generates—you create recursive loops of artifact tokens that quickly overwhelm the board and let you cast your entire library for free.
