Urza, Prince of Kroog + Magic Pot + Krark-Clan Ironworks + Worldwalker Helm

Urza, Prince of Kroog

Magic Pot

Krark-Clan Ironworks

Worldwalker Helm

How it works

1. Activate Urza by paying 6, creating a token copies of Magic Pot that is a 1/1 Soldiers and a Map token
2. Activate Krark-Clan Ironworks twice by sacrificing the Magic Pot and Map, adding CCCC.
3. When the Magic Pot token dies, it triggers, creating a Treasure and a Map token.
4. Activate Krark-Clan Ironworks by sacrificing the Map or Treasure, adding CC.
5. Repeat.

This loop gets its engine running when Urza, Prince of Kroog copies Magic Pot, an action that Worldwalker Helm instantly supercharges by generating an extra Map token alongside the new copy. You then feed those fresh artifacts into Krark-Clan Ironworks, harvesting colorless mana to fuel Urza's ability while triggering Magic Pot's death ability to keep the cycle going. Because Worldwalker Helm multiplies your token generation every step of the way, you easily outpace the mana spent to make the copies, resulting in infinite colorless mana, artifact tokens, and death triggers.
