Combos:
Cyberdark End Dragon is the best card in the deck by far with the two Overload Fusions (Require five Cyberdark banished) to summon it in the main spell. As it is search with the field card Cyberdark Inferno when destroyed, protection with the archetype of using the monster as spells. Then a Cyberdarkness Dragon needs a Cyber End Dragon in the graveyard to special to summon the main boss monster.
Cyberdark Claw gets Cyber End Dragon to the graveyard and is a dragon type. So in the damage calculation, you can discard in the extra deck when equipped with a machine Cyberdark plenty here. Also, discard from hand to draw any Cyberdark spell from the deck. Like Cyber Dragon Cannon but in reverse.
Cyberdark Chimera gets that singular Power Bond to hand easy for generic Cyberdark Dragon fusion with only 1000 attacks at first. Not getting the blowback of double attack plus monster equip bonus, sets up two Cyberdark Impact that allows recycling cards.
There is plenty of virus cards to implement but one of them like the Eradicator Epidemic Virus is good
The Number 82 and Zeus combo works basically every time to wipe the field
