Err... I don't think an angel that forgives you would walk straight up to the enemies and expect to be let in. It has a good sync with Liquid Shadow as other people stated, which worries me slightly because you can make some pretty good stalls, and stalls are actually a lot more powerful than they look.
The card seems balanced, as your opponent would have to waste non-AoE CC to get rid of it and it become a nuisance quickly, but that gets covered by a high cost.
