Is it recommended to go to Stage 45? I have a pretty consistent auto-duel deck for standard duelists lvl 39. Unfortunately I just reached the last Stage at GX, so I can't get any more gems and duelists there.
So in short: are the standard duelists at lvl 45 still easy to beat or are they not worth the extra gems?
lvl 45 is all Beatdown and the highest atk is 4200
