Seems like the deck sure can do what he is supposed to do, but it looks too one sided, the options you are are basically limited to Utopia, and however you are aways obligated to use 2 cards on your hand to bring it out, I still think the wind-ups (even with magician limited...) are still probally the best engine to bring out ZW, that still is enable to do a lot of things with a lot of options, because since the ZW XYZ is a Rank 5, it's even a problem to summon him with this, actually summoning the ZW XYZ doesn't seems very viable.
Cards like double or nothing, I don't think it's really necessary, with the attack power Utopia can archive with the ZW, it would be just for a possible OTK, since you don't run any MST, I'd rather go for things like, trap stun or even Decree, because most of the traps you run needs your opponent to attack to be used, and is mostly likely they don't will try to attack a 8000+ atk monster with all the ZW Stuff equiped, also a unequiped Utopia can protect himself with his own effect, if even then you wanna run some backrow, I'd say traps that toggle on summon are better, like Bottomless Traphole and even Torrential (since the ZW's can protect utopia anyway), Compulsory that you already have is also a nice trap card you can use, but since bottomless and torrential doesn't target... However, compulse sometimes is actually better.
