Mishra, Eminent One + Urza, Lord High Artificer + Worldwalker Helm + Urabrask the Hidden

Mishra, Eminent One

Urza, Lord High Artificer

Worldwalker Helm

Urabrask the Hidden

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 Mishra, Eminent One into an unstoppable factory by twisting the replacement effect of Worldwalker Helm: every time Mishra conjures a temporary 4/4 copy of the Helm, Worldwalker Helm doubles the bounty into both the creature copy and an extra Map token. Urza, Lord High Artificer acts as the engine's primary fuel source, turning those freshly minted Maps into an endless stream of blue mana whenever you tap them. Meanwhile, Urabrask the Hidden keeps your board aggressive with global haste, ensuring that the sheer avalanche of copied tokens can immediately join the fray or fuel further activations.
