Ok umm... I'm not that good at Yubel decks but this is what i think:
1. 52 Cards?! Boy we need to lower this.
First: we can take out Dark Resonator i mean Synchro Yubel? Not a good combo imo. (-3 Resonator, 49 cards)
Second: 2 of each Yubel? It's a great risk to Dead draw Thrice with that. I would say remove one of each (-3 Yubel Cards, 46 cards)
Third: Limit Reverse and Floral shield to 1 and 2, it's a little too much defense there so it's enough with that imo (-3 cards, 43 cards)
Fourth: Limiting the Silecers to 2 and the Avarice to one. That would work pretty good i belive (-3 cards, 40 cards)
That is how i would re-do it, but you decide yourself
