Clay-Fired Bricks // Cosmium Kiln + Ashnod's Altar + Urza, Prince of Kroog

Clay-Fired Bricks // Cosmium Kiln

Ashnod's Altar

Urza, Prince of Kroog

How it works

1. Activate Urza by paying 6, creating a token copy of Cosmium Kiln that is a 1/1 Soldier.
2. When the token Cosmium Kiln enters the battlefield, it triggers, creating two 1/1 Gnome artifact creature tokens.
3. Activate Ashnod's Altar three times by sacrificing the Cosmium Kiln token and the Gnomes, adding six C.
4. Repeat.

This loop turns Urza, Prince of Kroog into an incredible engine by using his ability to repeatedly copy the backside of Clay-Fired Bricks // Cosmium Kiln for six mana. Each time a token Cosmium Kiln enters the battlefield, it floods the board with two Gnomes, all while Urza's passive buff and Cosmium Kiln's static anthem ensure your growing army stays massive. You then feed those creatures straight into Ashnod's Altar, turning the sacrifices into the exact amount of colorless mana needed to fund the next Urza activation and keep the endless chain of artifact tokens going.
