Sphinx déchiffre-vent

Text:

Rulings:

• 7/13/2018 It doesn’t matter who controls the creature with flying or which player or planeswalker that creature is attacking. Windreader Sphinx’s controller is the player who may draw a card.
• 7/13/2018 Windreader Sphinx’s ability will trigger when it itself attacks.
• 7/13/2018 The creature must have flying immediately after being declared as an attacking creature in order for Windreader Sphinx’s ability to trigger. For example, attacking with Kitesail Corsair will cause the ability to trigger, and attacking with Pegasus Courser and a creature without flying will cause the ability to trigger only once.
