I've played control hunter alot over the years. I force it pretty much every expansion. You're right there are alot of strong additions this time around.
Theres a couple areas its usually weak in. Card generation/draw and healing. Also sometimes it feels like other classes have better finishing options.
Agro decks aren't that popular right now but that can change in a heart beat. I'd probably be running Death's Head Cultist and maybe Armor Vendor. Circus Medic is interesting a little inconsistent but interesting because it turns into a finisher.
For finishers there is the OTK package which is about 8 cards. I've been messing with that lately but it feels pretty inconsistent. Too dependent on drawing a Selective Breeder early. Corrupt package is interesting I just fear other classes do corrupt better. Hunter doesnt't really have great corrupt support. I actually think just an attrition build would fair ok. Just whittle them down with hero power and random stuff because theres not alot of healing in the meta. Except Warlock, they can heal so much from soul shards. That brings me to control hunters biggest problem imo, control/corrupt Warlock is just so strong right now (and its gonna get better after the nerfs). Going to be pretty hard to run control hunter into it.
I want to get around to trying the Primordial Protector package. I've seen a version on twitter with Guardian Animals that looked strong.
As for other suggestions, I've been liking a Trueaim Crescent package. It synergizes with Trampling Rhino Venomous Scorpid Explosive Sheep basically any minion really and it can just clear 1 health stuff on its own. Also those are good cards tho I'm on the fence about sheep. Maybe give it a try. Regarding Resizing Pouch, I just don't think its a good card. You lose a mana, its inconsistent, and doesn't generate extra value. Maybe there is mana cost thats better to target consistently that would make it better but it just felt bad in my limited testing.
Anyways goodluck always like to see some Control Hunter.
