ive been playing the deck for years and id recommend you play a set rotation because of how important diagram is. for the dinomorhpia package I personally play two kent one dip and one stealth so that you can get lower lp and if you rex can float better too. the side deck looks really clunky and should be more targeted for your particular locals. like you played agiast dm and lab with both have a hard time against cosmic which is also ok against the snake eye field spell and hours. on that point, the side deck is one of your most powerful tools in a best of 3 format and not using it really puts you at a disadvantage. dinos is one of my favorite decks of all time and I decided to dust it off for this weekend and play something more low-power
