Release the Ants

Oracle Text

Release the Ants deals 1 damage to target creature or player. Clash with an opponent. If you win, return Release the Ants to its owner's hand. (Each clashing player reveals the top card of his or her library, then puts that card on the top or bottom. A player wins if his or her card had a higher converted mana cost.)

Card Rulings

4/1/2008 If you win the clash, the spell moves from the stack to your hand as part of its resolution. It never hits the graveyard. If you don't win the clash, the spell is put into the graveyard from the stack as normal.
4/1/2008 If the spell is countered for any reason (for example, if all its targets become illegal), none of its effects happen. There is no clash, and the spell card won't be returned to your hand.
