Flying, vigilance
Whenever Kangee, Sky Warden attacks, attacking creatures with flying get +2/+0 until end of turn.
Whenever Kangee blocks, blocking creatures with flying get +0/+2 until end of turn.
Only attacking creatures that have flying as the first triggered ability resolves will get the +2/+0. Similarly, only blocking creatures that have flying as second triggered ability resolves will get +0/+2. Giving a creature flying or making it lose flying after that point won't change the bonus the creature has, if any.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
