Bluesky Dart

Sever (Each card that you exile at random from your library as you cast this spell pays for {1}.)
Dash {3}{u} (You may cast this spell for its dash cost. If you do, it gains haste, and it's returned from the battlefield to its owner's hand at the beginning of the next end step.)
Whenever a card is severed to Bluesky Dart, each other player exiles the top card of their library and it gets +1/+0 until end of turn.
