Striking Diamond
Artifact
Affinity for colorless nonland permanents (This spell costs {1} less to cast for each colorless nonland permanent you control.)
{1}, {T}: Add one mana of any color.
Adamant — When Striking Diamond enters the battlefield, if at least three mana of the same color was spent to cast it, put a light counter on Striking Diamond. For as long as it has a light counter on it, it has “{T}: Add one mana of any color.”
