Shards of Alara

Exile the top five cards of your library. An opponent separates those cards into two piles. You may play any number of cards from one of those pile...

Choose one — • Destroy target artifact. • Put target creature on the bottom of its owner's library. • Counter target instant spell.

[+1]: Target permanent doesn't untap during its controller's next untap step. [−2]: Ajani Vengeant deals 3 damage to any target and you gain 3 life...

Each player who has cast a nonartifact spell this turn can't cast additional nonartifact spells.
