dimensional glads don't bother with Darius. Just get rid of him altogether since you probly won't have much use for him during the duel. The random Airbellum can also get thrown out. Prisma also isn't used in Dimensional Glads since his eff also conflicts with D Fissure and Eatos. Compulsory Evac isn't really up to snuff nowadays so I suggest ditching that as well. Don't be worried about Stardust because War Chariot takes care of that just fine. I also only count 39 cards in the deck.

Add a 2nd Murmillo in case 1 gets beaten up, and 1 copy of Retiari who goes well with the strategy and is a good GB to have anyway.
Gorz needs to be here.
Tragoedia is also a good choice to add in.
You're missing Heavy Storm. I don't know if you're afraid of destroying your D Fissures or what, but get over it. Heavy Storm needs to be in the deck.
If you decide not to add Tragoedia, then I suggest your last slot get occupied by a 2nd copy of My Body as a Shield.
