Ah, fair enough! Avatar described it last page as "the first non-cheese strategy to a challenge that was built not to be beaten by any non-cheese strategies" so I was just going based on that. Description edited!
(I hadn't realized Vampire still worked after the bloodless golem change, and I've been deliberately avoiding finding out what heretic is capable of so I can figure out Heretic Gold on my own unspoiled.)
I think Purecaster Troll will be able to handle it, just because having fireballs only cost 4 mana and an innate out-of-combat-but-doesn't-use-darkness BLUDTOPOWA would be so strong here, but that can't really be tested until the nerf goes through. But if even Wizard is struggling, I'm not sure how viable other spellcasting classes would be...
