Dabok couldn't have said it better I added this card to a mill deck I built recently in place of the cloud fin raptors for a cheap flying 1 mana drop creature and its perfect for a mill deck. The only issues I see with it is that because of it's ability you tend to wanna hold onto it until after a few turns have passed and hopefully you have been able to mill your opponent enough for the +4/+4. Not the best turn one drop but it's great mid to late game because its so cheap a flying 5/5 for 1 mana, can't beat that.
