Dragons of Tarkir

Flying
Whenever a Dragon you control attacks, scry 1.
At the beginning of each combat, if a Dragon you control has first strike, Dragons you control gain
first strike until end of turn. The same is true of firebreathing, flying, deathtouch, double strike,
haste, hexproof, indestructible, lifelink, menace,
reach, trample, and vigilance.
