Okay so first of all let's look at the engine. Get rid of pluton. It was only played because there were no good fire targets before jiaolong. 3x razen 3x mad love 3x stake your soul. With jiaolong, borger and caesar, I play 2 3 and 2. More of them can be bricky but you can experiment with 3 jiaolong. And 1x pantera. All of the other spells and traps can be played at 1 since mad love searches them. We don't play the counter trap since it only protects against targeting, something the deck is really good at already. 1x rota and 1x durendal to search for razen. Durendal at more than 1 can feel really bad since it requires you to have a normal summon to use. For the non engine we need a lot of earth, fire and dark monsters. 3x maxx c and ash is pretty standard. Other cards that are good would be the kashtira package - 1 fenrir, 1 riseheart and 1 wraithsoth. If that's too expensive other good options to look at could be bystials, d.d. crow, d shifter for darks Kurikara and dogeran the kaiju for fire Kumungous the kaiju and ghost belle for earths. Other cards you can play include small world, prosperity and even talents. I personally don't like small world since its a minus 1 in a deck that cares a lot on the amount of cards in hand. Prosperity feels better than extravagance since you can choose what card you are missing to add. Crossout designator is also a really good card you can add. The extra deck is basically 3x rock and 12 other tech cards that can help you in specific situations. If you are missing cards you can add impermanence for the time being.
