This is just a much more balanced Brann, but it will still open the door for plenty of Shenanigans.

MY JAWS THAT BITE - Boner version

So if you play this guy + bloom + y'shaarj you'll get infinite circus medics?

Ding ding ding. 
There are better combos though. Cards busted

Probably :)

I don't even think you need this guy to OTK since he's also like a sethekk veil weaver in an elemental deck. I'm definitely gonna try him out with medic thou. It's a 4 card OTK where one can be tutored. What combo would you suggest?

I saw this and though shudderwalk, but it more like a weak bran. Prob won't affect battle cry doubling.

How will this work with battlecry doubling?

Mailbox Dancer with Pen Flinger is the first thing that comes to mind, and anything with lackeys or whatever would be brutal with a potent enough battlecry. (Ok, watching the reveal, that's the first combo they mention)

I have a couple decks that will truly welcome this card.

I am not sure how this exactly works:

when a card is played that buffs itself. Will the repeat effect buff the original minion or will Bolner repeat the battlecry as if he casted the battlecry himself?

Otherwise an updated bran bronzebeard:

Less mana to summon, repeats the most useful battlecry, reason to play penflinger.

So his best friend is Kindling Elemental? It's going to be such a weird deck.
