Warning that Golden Cards do not carry over between Heroes.
I did not know that golden cards did not carry over between heroes, so as far as I know I lost a couple when I stopped being the bounty hunter. Would be nice to work in some sort of tutorial, message before finishing a chapter, or some other unmissable hint that this will happen. If this behavior is not intended then I suppose just make sure they carry over between heroes? Same goes for the skill level increasing items, though I think those not carrying over is intentional.
