Vision

Vision's power and toughness are each equal
to twice the number of creatures you control.
At the beginning of each combat, if you control a creature with flying, Vision gains flying until end of turn. The same is true for First Strike, Double Strike, Deathtouch, Haste, Hexproof, Indestructible, Lifelink, Menace, Reach, Trample, and Vigilance.
