Twin Slop

This deck at it's core, is an Evil Twin/Fiendsmith deck with some secondary engines to help facilitate your combo and fortify your endboard. Evil Twin/Fiendsmith are famously weak against Nibiru. Thats why We run the DMG magicians apprentice, Diabellestar the Black Witch, and Apprentice Illusion Magician. The idea is to start with one Twin starter and one of these three spellcasters. Your gameplan is to normal summon your twin (Ideally main-deck Ki-sikil), effect to summon the other twin, then summon a spellcaster from hand, banish to summon DMOD, DMOD search gaze, then immediately use gaze on the DMOD on the field to summon Dragoon as your 5th summon. This helps you to secure the remainder of your combo without worry of Nibiru crashing the party. As a bonus, if you started with Diabellestar, you get to go into the small Azamina line ending with an Ilia Silva (extra Omni-negate) then after all that feel free to go crazy with the Evil Twin/Fiendsmith line. I like to end with Ilia Silva, Dragoon, Desirae with sequence attached, Trouble Sunny and A Bao A Qu. This gives 2 omni-negates, 1 negate of 2 cards on field, a pop and draw with the Trouble Sunny tag, and another pop or a revive of any light or dark monster (Ideal targets are Trouble Sunny or Dragoon if he gets removed). You also have a metalfoes fusion as discard fodder (a lot of effects in this deck need a discard) which can get you an extra draw for Dragoon/A Bao, and Duality (I'm experimenting with this one rn, not sure if it's worth it yet but it seems good.) This can either be used as discard fodder or used on your extra spellcasters to summon Fortune Lady Every for some follow up in case your opponent fully or partially cracks your board. Overall it is pretty strong even in the current meta, that being said it has some flaws. 1: every power play is a monster card on field, so the endbaord is VERY susceptible to Dark Ruler No More and Forbidden Droplet and can even have problems if your Silva and Dragoon get Lava Golemed. 2: I couldn't find a way to bring it down to 40 and keep the ratios I like, but the amount of draws you get can make up for the extra main-deck size. That being said it can probably be fine to knock off some of the non-engine and even a couple starters to get it down to 40. At the end of the day, this is just what I've found I have the best success with after trying numerous iterations of this list, so by all means, if you want to give it a go and maybe improve on this then be my guest!
