Can confirm, was shown on Korean Blizzard's stream, I saw the reveal.
and yes, it is a neutral card that summons silver hand recruits. So it's made neutral so other classes maybe have a chance at getting an inspire ability just to get some tokens, while Paladins get even more from it due to quartermaster synergy- or of least I assume that's the reasoning behind it.
and the source? the other two were revealed, as already said, on a korean livestram, therefore legit. But how about that one? It also breaks with the good demon for negative battlecry thingy, but more important, out of al classes, why should WARLOCK need a draw engine?
I can't stop laughing. Just the idea of someone posting a 'leaked' hearthstone card for the new expansion, with a very suspicious draw engine for Warlock, and somewhere, someone's reaction is just 'DAMN LOOK AT THOSE TITTIES'.
