The main deck is your typical Dinomorphia Z-ARC build, but I've added some sauce that I think could allow the deck to stand out more. One card that fascinates and leaves me wondering why I waited so long to try it is Dinomorphia Revision.
People don't usually run it, but I personally think it could be really clutch when it needs to be. Instead of copying just a Dinomorphia Counter Trap, it copies ANY Counter Traps in your graveyard. Which means this card is functionnaly an additional copy of all the counter traps you run. Even if you use it to copy Intact or Sonic, Reversion has the grave effect to prevent battle damage, so you don't even missout on having that extra protection. But since it can also be Solemn Judgment and Strike, Iron Thunder and Debunk, it makes it more effective than it seems.
The requirement to activate it is probably what turns people off from it, but if Kentregina and/or Rexterm is all I need to have a searchable Solemn Judgment, I'm down.
With the Extra Deck, I've divided it into two sections: Dinomorphia and Z-ARC. No Dolkka or Laggia, which I've never been in many situations to make them in the first place, so that's just a me thing, mostly. However, the Z-ARC side is split into two sub-sections of defensive options and aggro options. The defensive options are Crystal Clear Wing and Brave-Eyes, Synchro and Pendulum respectively. They are for if I activate SotSK on my opponent's turn to shut their plays down more effectively.
The aggro options I opted for are Crystal Wing and Odd-Eyes Rebellion, Synchro and Xyz respectively. They are for when I activate SotSK on my turn, when I can attcak. Crystal Wing is an amazing battler when I decide to read ALL of its text and Odd-Eyes is a more interesting case.
OER has a stipulation that it can't be summoned the turn it is Xyz summoned. However, since it isn't being Xyz summoned, OER can be used for an Xyz material the turn it is summoned to make the Rebellion Overlord Dragon, a monster that makes closing out the game much easier, something Dinomorphia struggles with at times. This small interaction alone makes OER and Overlord Dragon far more worth it than the Fusion Dragons.
Not to mention that if OER is destroyed for any reason, it can go to the Pendulum Zone, then you can activate its effect in the PZ to summon it and attach a Dark monster from your graveyard to it, making it helpful in a potential grind game and even clear up your opponent's board to swing in more comfortably.
