Standard Crystron package with some additional Cydra cards.
Cyberdark Realm line through Chimera and Wurm gets access to Clockwork Night to threaten board wipes and force out negation without normal summoning, as well as make Heosvarog going first. Same line can pitch Clockwork Knight to search Regulus for an omni (BEATS NIBIRU), or it can be left on field as a floodgate, or a Crystron can pop it. More machines on board helps make Qliphort Genius prior to Tristaros effect to summon 2 from deck; also searches Regulus. Nachster in hand can pitch Crystrons for grave effects. Running more than 40 to hide bricks like Cyberdark Chimera and Power Bond. Ideal endboard going first (Cyberdark Realm + Smiger in hand or grave) can end on S:P, Heosvarog, Regulus, Infinity, Dragster, Tristaros, and Cluster. Tristaros can't activate immediately but Heosvarog and Regulus both jump off the board when they use their negates.
I've found Crystron can have some difficulty OTKing after playing through opponent's interaction - this list can generate a lot more damage, particularly due to funny synergies like where Nova can bring back Nachster from grave, which then can summon Eleskeletus since it has 2100 DEF, and Eleskeletus debuffs the opponent's ATK/DEF by 500. Nova can then banish that Nachster to gain 2100 - with Eleskeletus and Clockwork Night, you can beat over almost anything.
Tried running Core but didn't love that it used the normal and is such an easy choke point. Obviously some Crystron hands don't need to normal but it's a lot stronger and more versatile if they can.
Would run Charmies and Thrust for more going second options if I owned them. Leave a comment if you have any suggestions and let know if anyone wants me to show combo.
