Mostly because I love the Archetype even if it's never more than Rogue level competitive.
Cyber Dragon Bridge
1000 ATK/1000 DEF
This card's name is treated as "Cyber Dragon" while in the graveyard. You may banish 1 LIGHT Machine-type monster from your graveyard to Special Summon 1 "Cyber Dragon" monster from your deck. Cards that are special summoned by this effect cannot activate their effects.
Cyber Prism Dragon
2000 ATK/2800 DEF
"Cyber Dragon" + 1 LIGHT Machine-type monster
Your opponent cannot target other Machine-type monsters you control for card effects. When this card is targeted for a card effect, you may banish 1 "Cyber Dragon" from your graveyard to negate the effect.
Cyber Plasma Dragon
3000 ATK/2500 DEF
"Cyber Dragon" + 2 LIGHT Machine-type monsters
Monsters destroyed in battle by a LIGHT Machine-type monster cannot activate their effects in the graveyard (this effect applies as long as the destroyed monster remains in the graveyard). This card inflicts piercing battle damage.
Chimeratech Void Dragon
4000 ATK/2800 DEF
3 "Cyber Dragon" monsters
This card must be special summoned through Fusion Summon and cannot be summoned by any other means. When this card is Fusion Summoned, banish all set cards on the field. Cards and effects cannot be activated in response to this effect. When this card declares an attack, your opponent cannot activate cards or effects until the end of the damage step.
Chimeratech Union Dragon
1000 ATK/4000 DEF
"Cyber Dragon Bridge" + 2 or more non-tuner LIGHT Machine-type monsters
Your opponent cannot select another Machine-type monster as an attack target. If this card attacks, you may increase its ATK by the combined ATK of all other Machine-type monsters you control during the damage step only. Other monsters cannot declare an attack the turn you use this effect.
Activate only while you control a Cyber Dragon monster or monster that lists a Cyber Dragon monster as a material, banish any number of Cyber Dragons from your graveyard; banish a number of cards from your opponent's field equal to the number of monsters banished from your graveyard. If a card is banished by this effect, you cannot declare an attack in the same turn.
Cyber Dragon monsters and monsters that list a Cyber Dragon monster as a material (that you control) cannot have their ATK or DEF modified by your opponent's card effects.
Cyber Dragon monsters and monsters that list a Cyber Dragon monster as a material (that you control) cannot have their control switched nor battle positions changed or controlled by an opponent's card effect.
I'm not really expecting these to somehow make Cyber Dragons meta, and you are free to evaluate them outside of Legacy thinking.
