Ayula, Tamer of Mists

Obscure (Whenever this creature is blocked, put another creature from your hand onto the battlefield facedown tapped as a 3/3 being blocked instead and return this card to your hand. Flip an obscuring creature faceup by paying its mana cost; do this only as a sorcery.)
When this creature becomes Obscured, you may pay {3}{g}{w}{u}. If you do, flip the creature faceup.
Whenever this creature deals combat damage to a player, draw 3 cards.
