Legendary Creature - Elder Dragon | Power/Toughness: 3 / 5 (CMC 4)
Flying, vigilance
Whenever a creature with defender enters the battlefield under your control, draw a card.
Each creature you control with defender assigns combat damage equal to its toughness rather than its power and can attack as though it didn't have defender.
