Exitia Charm

Choose one -
* Destroy all artifacts. Draw a card for each artifact destroyed this way.
* Draw two cards, then discard a card. Exitia Charm deals damage equal to the discarded card's converted mana cost to two target creatures and/or players.
* Counter target spell. If a spell is countered this way, you may cast a nonland card from your hand that shares a card type with the countered spell without paying its mana cost.
