Legendary Creature — Sphinx
3/6
Flying
Whenever Isperia deals combat damage to a player, choose a card name. That player reveals their hand. If a card with the chosen name is revealed this way, search your library for a creature card with flying, reveal it, put it into your hand, then shuffle.
Rulings
- The card is named when the ability resolves. The named card can't be played after it's named but before the player's hand is revealed.
