Cyber Dragons are known for being OTK decks with their extra deck monsters, Cyber End Dragon being the most iconic. Though OTKs are what most Cyber Dragon decks are known for the purpose of this Cyber Dragon deck build deck is to be a control beatdown deck using Cybernetic Overflow to help control, Cyber Dragon Infinity to help stun, and Cyberload Fusion to help push for OTK. There are various ways to go into Cyber Dragon Nova and Cyber Dragon Infinity YET timing their summons is crucial. Several times going into Cyber Dragon Nova and Cyber Dragon Infinity is not necessary.
This deck build runs 3 copies of Cybernetic Overflow to help control and 2 copies of Cyberload Fusion to take full advantage of Cybernetic Overflow's banishing costs (Keep in mind that if Cybernetic Overflow is destroyed while on field it becomes an extender by helping add 1 "Cyber" Spell/Trap from deck to hand). Machine Duplication is a VERY powerful card and is ran at 2, 3 can become bricks. (Helps go into Cyber Dragon Nova which can then go into Cyber Dragon Infinity very quickly). Cyber Repair Plant is ran at 3 to further help deck search especially when needing to search for Jizukiru, the Star Destroying Kaiju. (Can easily be ran at 2 or 1 depending on preference). Foolish Burial is primarily used to trigger Cyber Dragon Herz (Can also be used to set up a Cyber Dragon in GY if Cyber Dragon Nachster is in hand for Cyber Dragon Nachster to be normal or special summoned to then target Cyber Dragon in GY and special summon it OR to have more Cyber Dragon variety in GY for Cybernetic Overflow's banishing costs). One for One is primarily used to help set up a board for Machine Duplication though One for One can be used in many different ways depending on resources on field, hand and grave (Can be used to send Cyber Dragon Herz from hand to GY to trigger Herz effect, Can be used to special summon Herz to trigger Herz special summon effect, Can be used to special summon Cyber Dragon Nachster to trigger Cyber Dragon Nachster's effect, Can be used to help set the board for a Cyber Dragon Drei normal summon effect, Can be used to have variance for Cybernetic Overflow). Running 2 Cyber Dragon Sieger, 2 Chimeratech Fortress Dragon and 2 Chimeratech Megafleet Dragon makes this build a bit more competitive and can easily be done by taking out the 3 Cyberdark fusion monsters.
Key Takeaways:
Cyber Dragon Core - Literally the core of this deck. Normal summon to add 1 "Cyber" Spell/trap from deck to hand. Can literally search all "Cyber" Spell/Trap cards including Cyberdark spells and traps. Cyber Dragon Core can be targeted by Machine Duplication.
Cyber Emergency - Literally the extender of this deck. Adds 1 "Cyber Dragon" monster from deck to hand or 1 Light machine monster that cannot be normal summoned/Set (Cyber Eltanin)
Cyber Dragon Herz - When Special summoned its level becomes 5. When sent to graveyard it allows to to add 1 "Cyber Dragon" from Deck or GY to hand. (Keep in mind all monsters in this deck build are considered "Cyber Dragon" when on field or graveyard, allowing Cyber Dragon Herz to add any Cyber Dragon monsters from graveyard back to hand). Cyber Dragon Herz can be targeted by Machine Duplication.
Cyber Dragon Nachster - When normal or special summoned you can target 1 machine monster with 2100 ATK or DEF in your GY, special summon it. (Ideal combo is to special summon Cyber Dragon Nachster from hand by sending an original Cyber Dragon from hand to GY then targeting that sent Cyber Dragon in GY and special summoning it. Targets that Cyber Dragon Nachster can special summon from graveyard are Cyber Dragon, Cyber Dragon Nova,Cyber Dragon Infinity, Cyberdark Chimera. Cyber Twin Dragon, and Chimeratech Rampage Dragon) Cyber Dragon Nachster can be targeted by Machine Duplication.
Cyber Dragon Drei - When normal summoned you can make all "Cyber Dragon" you currently control become level 5. (Ideal combo for Cyber Dragon Drei is activating Cyber Dragon Nachster effect in hand to special summon Cyber Dragon Nachster then following up with normal summoning Cyber Dragon Drei to convert all Cyber Dragon monsters on field to LVL 5 then to go into Cyber Dragon Nova and Cyber Dragon Infinity). Another way to make Cyber Dragon Nova is by having Cyber Dragon Vier in hand when normal summoning Cyber Dragon Drei. (When normal summoned Cyber Dragon Drei's effect can be activated AND Cyber Dragon Vier's special summon effect can be chained to Cyber Dragon Drei's effect to make both Cyber Dragon Drei and Cyber Dragon Vier level 5).
Cyber Dragon Vier - Can be Special summoned from hand in DEF position if you normal or special summon "Cyber Dragon". Gives each "Cyber Dragon: you control a 500 ATK and DEF boost. (This is a special summon after summoning any Cyber Dragon monster. Helps have resources for going into Cyber Dragon Sieger AND can be chained to Cyber Dragon Drei's normal summon effect to help make resources for Cyber Dragon Nova).
Cyber Eltanin - helps clear the board; when summoned, sends all monsters on the field to the GY. Can be searched with Cyber Emergency and Cyber Repair Plant. Cyber Eltanin's special summon requirements also helps push all Cyber Dragon variants from fiedl and GY to the banish pile setting up resources for a Cyberload Fusion OTK.
Jizukiru, Kaiju - helps get rid of an opponent's OMNI negate and can be contact fused with any "Cyber Dragon" on the field to make Chimeratech Fortress Dragon. Can also be used to make Chimeratech Megafleet Dragon if opponent has a monster in an extra monster zone. Can only be searched with Cyber Repair Plant.
Cyberdark Side Deck
Cyberdark cards can easily be swapped in by cutting down on "3 ofs" and "2 ofs".
When swapping in Cyberdark cards please keep in mind that this dilutes the Cyber Dragon
deck build consistency. Having familiarity with how how Cyber Dragon and Cyberdark work individually vastly helps. When familiarized and when playing a hybrid deck more than not Cyber Dragon and Cyberdark build on top of another. Both Cyber Dragon Core and Cybernetic Overflow strongly support both archetypes due to how both are capable of searching any Cyber spell/trap.
Ideally these are the cards that are removed from the main deck and the whole side deck is then swapped in to make a Cyber Dragon/Cyberdark deck:
Cyber Dragon Herz (-1)
Cyber Drago Nachster (-1)
Cyber Dragon Drei (-1)
Cyber Dragon Vier (-1)
Jizukiru, the Star Destroying Kaiju (-1)
Cyber Eltanin (-1)
Cyber Emergency (-1)
Cyber Repair Plant (-1)
Cyber Revsystem (-1)
Cyberload Fusion (-1)
Machine Duplication (-1)
Red Reboot (-1)
