Most of the suggestions in the thread would just make the quest unplayable, and it's already a low winrate deck.

That's why every single person at GMs recently brought some form of a questlock deck. It's such a low winrate deck. All those clowns are just memeing on us bringing such a low winrate deck. How silly.
What I think yourself and many others that craft questlock might be failing to take into account is that D6 (which is the iteration that many GMs played and that many people have crafted) is a high skill cap decklist that can be incredibly strong in the hands of a top tier pro but not necessarily so much when piloted by the average player or even most people in legend. That deck actually does have a relatively low wr at every rank where it is played including legend, and the reason why is that it is difficult to play optimally. So I think context is important to take into account here.
