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.
