Miriarca Maestoso

Majestic Myriarch's power and toughness are each equal to twice the number of creatures you control.

At the beginning of each combat, this creature gains flying until end of turn if you control a creature with flying. The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance.
