So this fever dream requires explaining.
First off, the Multiplication of Ants in the deck is a stand-in for Multiplying Kuriboh that is not this site yet.
The main goal of the deck is simple: beat your opponent with a giant Kuribabylon. The problem is that the archetype is quite inconsistent, so here's the thought process of fixing that. Linkslayer, Disablaster, Red Layer & Barox / Best Monster of 2017 (via Ready Fusion) are lvl 5s that can special summon themselves for free (with some conditions) and the maindecks can also be tribute summoned (to be the only thing on your field). The fives are important for enabling Five Star Twilight, which gets us all the gang on board. Kuribee is the searcher for the spell so it's empathic to have access to it, usually via Kuribah who can summon it directly off the deck (as does Multiplying). Kuribeh is not good but we need the names and the buff can occasionally be fun, if it comes to reviving some light kuriboh off Agnumday and then making it even bigger. The og is also not useful but for its name, and Kuriboo can also search another one, but brings it to hand only. Other than the five kuristars, we have Kuribohrn who can help wall with either effect (and is also a light fiend), Detonating helps wall and can be interruption, Rainbow is bad but is a name and a light fiend, Barokuriboh can search by destroying itself.
Now for the reason Kuribandit is in the deck, and the reason we're going for 60. Kuribabylon benefits off a full grave, both for the stats and its summoning condition, but I opted for some support, to make sure the games can close and there is an occasional turn-1 play other than "Set Bee, pass". As such, Mutiny in the Sky can live very easily through a combination of Bandit / Twilight & Reasoning / Grass, making primarily Luce (who triggers off Barok popping itself). There other side to this is the Fiendsmith engine, which can simply fuel the grave more with Tract being able to fetch Bohrn or Rainbow, but also making its own line, easily via Lurrie going for the Requiem for Lacrima for Engraver for Sequence for (usually) Desirae for Agnumday for either reviving and strapping Desirae with Requiem too, or per wacky occasion reviving a kuriboh for maximum mockery.
Maybe Lurrie can be omitted from the list to make the fiendsmith line less easy to access. Lastly for the main deck, Dystopia the Despondent is a classic, and where else can one summon an unsearchable 5k/5k with neary a worthwhile protection that even nerfs your board. Classic I say.
Regarding the rest of the extra deck, Necroquip Princess is another fusion summoned like a Link-1 that can draw a card, Goddess after Twilight or Bohrn can help fix some mucky game states, while Saryuja after Twilight or Bohrn can dig for a card. S:P is invaluable, being able to banish herself to leave the field open to have a single lvl 5 on board for Twilight, Pentestag can help Babylon punch better. Linkuriboh can help walling, and Anima is jumpscare removal.
Regarding alternatives, Winged + Flute + LV6 provide more umph but I don't think are worth the space, Mystic Tomato can be a decent choice if the desire is for a much weaker list without the fusion aspects, Brown Magician can become lvl 5 but wants a deck heavier on spells (power spell board breaker version?), Ankuriboh is neat (?).
Sylvan Princessprite can "dig" for spells but can also become a giant space mech, the Knightmare trio is generic utility. Maybe cards like Dark Hole also fit for clearing the field for the 5s to drop. Tualatin is funny.
An entirely different version could be made with Sphere, Relinkuriboh , Relinquished & Millennium-Eyes Restrict.
I have been informed by an associate nutcase that there could be a line via Aerial Eater and Sangan to make the Fiendsmith act as a bridge for the Kuriboh side. While it sounds cool, I have been in the tank far too long already.
In case it wasn't obvious, there are not handtraps here, and the deck's power level is slightly above the floor, but hopefully it can be fun enough for people to try and / or experiment with it.
