#: 132

Rules Text Contains: Excavation Explosion deals 3 damage to any target. Create a tapped Powerstone token. (It's an artifact with "T: Add C. This mana can't be spent to cast a nonartifact spell.")
Flavor: Urza's engineers could take weeks to dig out a powerstone. The goblins weren't so painstaking.
