Rate/fix my Cyberdark deck ( Is it Tournament Ready?)?

ok little change i would make is just to remove future fusion and replace it with one polymerization and one dragon mirror. The problem with future fusion is after you bring out the fusion monster all your opponent has to do is destroy the future fusion spell card and the monster goes to and they dont even have to do that after they can do it before the monster is brought to the field. But other than that i couldnt find anything wrong. 8/10. I cant tell you if its tournament ready cause i havent dueled agaisnt it and wouldnt know how well it works. But on paper this deck looks good.
