You got most of the staples down, which is good. I would try and fit in TG1-EM1 (max 2) over the other T.G. trap.
- Quillbolt, It isn't necessary to run over other cards in your deck
- The Thunder Kings. The deck runs off of searching card when being destroyed and sent to the graveyard. Why would you disrupt the +/card advantage you get off your deck?
- Cyber valley, this isn't a stall deck, and deck thinning isn't necessary. The deck doesn't impliment a strategy needed for this card either.
- Foolish Burial, It does nothing for the deck. No cards go off from sending a monster to the grave, no card is used for set-up (like inzektor hornet in inzektors), and you don't require specific cards to hit the grave for Chaos and other combos in the deck.
Trag is debatable, but I would still trade it for cards like TGU.
+1 BLS and +1 Chaos Sorcerer. You have enough Dark and Light Targets to run both of these cards.
Fiendish Chain is more effective than D-prison this format, as Preventing monsters to attack and negating their effects are brutal. You talking about with the release of HA7, this card will be effective against Verz, Fire Fists, Constellar, etc.
- 1 of the synchro blaster, - the lv6 fire synchro, - lightning warrior, - the 2nd synchro (going from left to right), and - Starform. Starform isn't needed, as your cards work from being destroyed and sent to the grave. You don't need high viable (not getting destroyed by battle or card effects) but mere backrow will help you with your major issues in game.
+ Scrap Dragon (works off destroying your cards and your opponent for a +1) + Black Rose, its a staple when you run synchros for nearly all decks, + Zenmaines, and +Leviathan (if you are adding TGU).
+ 2 MST. Dark bribe should not preside over mst if that was what you are thinking. Dark Bribe you only want to add a deck, where You Must always have your backrow ( Token Beatdown deck for example), (Continuous Trap Deck). The main reason is the fact your opponent +1 off of you, which in general you don't your opponent to gain card advantage over you.
+2 Duality if you have room. You want to maintain concistency within the deck, and considering your deck doesn't special summon every turn and uses heavy backrow, this is a good card you want to add (Noticing you rarely add duality to your decks, when it is a staple for the most part). Most meta don't need duality this format, because they have many ways to search their key cards so.....yeah about that.
For the most part, I think you did good on your 1st try with T.G. Let me know what you think, if you edited it to what I suggested.
