Urza, Prince of Kroog + Magic Pot + Parallel Lives + Thermopod

Urza, Prince of Kroog

Magic Pot

Parallel Lives

Thermopod

How it works

1. Activate Urza by paying 6, creating two token copies of Magic Pot that are 1/1 Soldiers.
2. Activate Thermopod twice by sacrificing the Magic Pot tokens, adding .
3. When the Magic Pot tokens die, they trigger, creating four Treasure tokens.
4. Activate the Treasures by tapping and sacrificing them, adding 4.
5. Repeat.

This loop turns Urza, Prince of Kroog's six-mana token-copy ability into a self-sustaining engine by leaning heavily on Parallel Lives to double your output at every iteration. When you pay to copy Magic Pot, Parallel Lives steps in to double those tokens to two, which you immediately feed into Thermopod to generate red mana and trigger the Magic Pots' own death abilities. Because Parallel Lives is also watching those death triggers, each Magic Pot dying creates two Treasure tokens, which then double into four Treasures that more than pay for Urza, Prince of Kroog's activation cost.
