so how does the deck win?

Best to look at odd priest, even rogue etc the unusual ones once all the cards are reveled. All Baku and gen decks are likely to get better and more versatile as more cards are added to the pool

Bro add Happy Ghoul. It will be able to help fill some of those empty turns.

The hero power is and always will be too weak to get a good gain from going odd Priest.
I don't think this is ever going to work out.

I tried to make odd priest work, and it never did for me because hero power in odd decks needs to be good on it's own on turn 2 because you almost never have anything else to do.

Paladin and Rogue get lots of value and tempo out of turn 2 hero power. Warrior at least gets to start going ham on armor. 

Priest gets the shaft because it will in almost every single game, heal its own face for 0-2 hp; not a good tempo play. The deck wants to be mid-range with all the health buffing and healing effects, so it's really easy to get outpaced in a zoo meta. 

I don't think the additional cards will help the archetype at all. 

I agree with the weak upgraded heropower.  However i think the real reason to play odd priest is the glitter moth... But i didn't manage to make it work, i tried several lists but it laks of consistency

I have a deck similar to this that is very fun to play.  I like that you are using Acolyte of Pain, though.  Looks like it would def help draw with the new cards.  Any room for Inner Fire?  I think you may be missing out with Glitter Moth.

Likewise with Void Ripper... following Glitter Moth with Void Ripper in a deck like this could give some insane burst.
