Prototyped Sprite

As Prototyped Sprite enters the battlefield, you may exile a creature card from a graveyard. If you do, Prototyped Sprite enters the battlefield with X additional +1/+1 counters on it, where X is that card's power. You may pay {8}. If you do, repeat this process.
Prototyped Sprite has all abilities and types of cards exiled with it.
