Majestic Myriarch

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