Damping Sphere

Artifact • Mana cost: {2} • Dominaria Remastered • Uncommon

If a land is tapped for two or more mana, it produces {C} instead of any other type and amount.
Each spell a player casts costs {1} more to cast for each other spell that player has cast this turn.

A Thran relic, it has spent ten thousand years doing absolutely nothing.
