Pounce (You may cast this card any time you could cast an Instant for {1}{r/w}{r/w}{r/w}. If you do, return it to your hand at the beginning of the next end step.)
If you cast Soaring Goard during an opponent's turn, it may fight target creature that player controls, otherwise it enters the battlefield with a +1/+1 counter on it.
