Kraj, the All-Consuming

Symbiosis {u}{g} ({u}{g}: Pair this creature with an unpaired creature you control. They remain paired for as long as you control both of them.)
Kraj can pair with more than one creature.
As long as Kraj is paired with a creature with flying, Kraj and each creature it's paired with has flying. The same is true for deathtouch, hexproof, indestructible, menace, reach, trample and vigilance.
