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.
"Let their horrors and machines come. We will meet them blow for blow."
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.
