Also the theme is off. I mean, I understand that it's supposed to imply exorcism, so that the purified minion decides to join the priest. But it could've had a Deathrattle restriction (and reduced cost to compensate or something) to reflect that it's supposed to cleanse evil. In this state it's pretty strange that hitting someone on the head with a bottle and killing him would convince him to change sides.
Let's consider Faceless Manipulator, for 5 mana you kinda 'add a copy of a minion to your hand and play it'.
4 damage better than play the minion?
Let's consider Entomb : for 6 mana you kinda 'kill a minion and add a copy of it into your deck' . For 1 more mana, you don't have the situational 4 mana damage condition, and it helps you on fatigue matchups (where the value stealing is actually important).
And again, if you care about your opponent's value, why don't you play non-situational value yourself?
If you considering the average HS matchup, this card will never see play...
I voted Very Good, just cuz of the sheer potential this card has. As Kripp said in the reveal video, the card requires a lot of testing to find the right synergies and situations you want to use it, but I am pretty sure enough of players will do that. Not only in constructed, but in Arena format as well.
So much potential.

People need to realize that priest is loosing like the whole dragon package (including duskbreaker reliability), dragonfire potion, shadow word horror. It will have a really hard time without good AOE versus aggro. Control (not combo) priest has already a pretty hard time vs. Murlocs.
So this card definitely has a spot, but I dont know, if it is fast enough to compete...
Convert was never really used. I'd be surprised if this saw play despite having some additional damage tacked on.
You could only play it on enemy minions and would get no tempo out of it. This is primarily 4 damage and this can target your own for the copy effect or damage to trigger deathrattles.
There's far better ways to trigger deathrattles and priest has plenty of copy effects that go straight on the board as opposed to going into your hand. If you're wasting 5 mana to cast this on your own minion, that's a massive waste of tempo already. May as well have just played Zola for the copy instead.
