Fish Xyz Synchro Reborn!!

This deck is quite interesting, I dont have any suggestions but I am curious how well it works. But why did u not go with two msts instead?

Decks like Fire Fists say I *FXck you" MST because they dont need to stay face-up for their effect to go off, as it is the same for cards like Dimensional Prison and Compulsory Evacuation device. My only threat is being out predicted so Night Beam is a good card to have with a nice uncountable niche.
