Kialla, Gaze of Infinity

Flash
Kialla, Gaze of Infinity enters the battlefield with
X +1/+1 counters on it.
Whenever you would draw a card for the first time each turn, instead exile the top X cards of your library, where X is Kialla's power. Until end of turn, you may play cards exiled this way, and you may cast spells exiled this way as though they had flash.
