Flying (This creature can't be blocked except by creatures with flying or reach.)

Whenever one or more creatures you control attack, they gain indestructible until end of turn. (Damage and effects that say "destroy" don't destroy them.)

Prevent the next X damage that would be dealt to any target this turn. Until end of turn, you may pay any time you could cast an instant. If you do, prevent the next 1 damage that would be dealt to that permanent or player this turn.
