K9 Crystron

Messed around with the concept a bit, and turns out Jokull + Sulfador in hand creates a full Crystron + K9 endboard that's completely Nib resistant thanks to early Ripper.

Jokull effect > summon Jokull + Sulfador >  Sulfador foolish 2 (probably Thyst + Smiger) > XYZ Ripper (Droll protection), detach Jokull to add Lantern > Lantern effect, summon + Jokull > Lantern add Forced Liberation, Jokull add Izuna > Thyst add Trist, Smiger add Inclusion, Inclusion add Cluster > Normal Trist, synchro 7 with Jokull for Eleskeletus (add Smiger) > Trist pop Ele for Sulfefnir + Sulfador > Ele trigger for Trist > Nova/Infinity > set Cluster + Forced. Lantern is fodder for Quariongandrax on your opponent's turn (Trist quick synchro, summon Citree, Lantern + Citree + Trist).

With a bit more extension, you can also turn Lantern + 2-ner into a premade Dawn Dragster, then resummon the 2-ner with Inclusion.

The 14 non-engine is even technically 16 thanks to the Izuna + Lupus package. This extra deck is extremely cramped, and maybe the main deck should get pushed above 40 cards for more engine/non-engine since there's so many one-ofs in here.

EDIT April 2025: Updated for the Infinitrack/Scrap Recycler bridge, that package is kinda nuts for bridging pure K9 into full Crystron combo. I'd also like to raise Prasiortle as a possible option, because it's a way to make use of the Scrap Recycler that's stuck on field at the end of the bridge...or you can just link off Clockwork Knight + Scrap Recycler into S:P before getting machine locked by Crystron stuff.
