Urza, Prince of Kroog + Magic Pot + Phyrexian Altar + Exalted Sunborn

Urza, Prince of Kroog

Magic Pot

Phyrexian Altar

Exalted Sunborn

How it works

1. Activate Urza by paying 6, creating two token copies of Magic Pot that are 1/1 Soldiers.
2. Activate Phyrexian Altar twice by sacrificing the Magic Pot tokens, adding 2.
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 creates a marvelous self-sustaining engine built around token multiplication and sacrifice. With Urza, Prince of Kroog on the field to copy your artifacts and Exalted Sunborn doubling any tokens you create, activating Urza's six-mana ability doesn't just make a single copy of Magic Pot—it floods the board with them. Once you sacrifice those soldier-pot tokens to Phyrexian Altar, the resulting death triggers on Magic Pot generate a wave of Treasure tokens that easily pay for the next activation. The Altar provides the exact mana you need to fuel Urza's ability again, letting you repeat the cycle indefinitely to churn through your entire library's worth of triggers.
