This is the second card I ever designed. The only thing that ever changed was the name, it was titled "Stone Hammer". Storm Hammer - 5 Artifact XX3, T: Destroy X target permanents in play. They cannot be regenerated. Use this ability only during your turn and only once each turn. This is probably too narrow of a card, as it can be severely abused with mana generators. Then again, that's the bane of all spells or abilities with X in the cost.
