Strategic Profile: The "Going-Second" OTK Machine

The archetype's primary, historical identity is as a "Going-Second" deck, designed to dismantle an opponent's established board and achieve a One-Turn Kill (OTK). While modern builds have developed robust "Going-First" combo lines, the deck's most powerful and theme-defining cards are inherently offensive tools designed for board-breaking and explosive damage. The central challenge for any Cyber Dragon duelist is to construct a deck that successfully balances the resource-intensive "Going-First" control setup with the aggressive, "all-or-nothing" OTK plays required when "Going-Second".

Foundational Mechanics

The Central Resource: The "Cyber Dragon" Name

The single most important mechanic is a shared line of text: "This card's name becomes 'Cyber Dragon' while on the field or in the GY." This effect, found on starters like Core, Herz, and Nachster, is the central linchpin. It provides the "fuel" for the entire engine, enabling Fusion Summons, search spells like Cyber Repair Plant, and removal traps like Cybernetic Overflow that all require the specific "Cyber Dragon" name.

The Two Faces of Fusion

The deck's power comes from two distinct Fusion mechanics:

1. Standard Fusion: Using Spells like Power Bond (for OTKs) or Overload Fusion (for GY recursion) to summon monsters like Chimeratech Rampage Dragon.

2. "Contact Fusion": An inherent summon that does not use a spell. It uses monsters from either field as material, acting as powerful, non-destruction removal. Megafleet Dragon absorbs monsters from the Extra Monster Zone, while Fortress Dragon absorbs all other Machine monsters on the field.

The Core Infrastructure: Key Cards

Main Deck Engine & Extenders

Cyber Dragon Core

The deck's most crucial 1-card starter. On Normal Summon, it searches any "Cyber" Spell/Trap. Its GY effect can also banish itself to summon a "Cyber Dragon" from the deck.

Cyber Dragon Herz

The primary resource recycler. When sent to the GY (even as a cost), it adds another "Cyber Dragon" from the Deck or GY to hand, turning discard costs into searches.

Cyber Dragon Nachster

A key extender and recovery tool. Can be Special Summoned from hand by discarding a monster (triggering Herz). On summon, it revives a 2100 ATK/DEF Machine from GY (like Infinity).

Galaxy Soldier

The most important "Nova Enabler." Special Summons itself from hand by discarding a LIGHT monster (like Herz). It's a Level 5 Machine, making it perfect Xyz material for Nova.

Cyberdark Chimera

The modern "OTK Enabler." Discards a S/T to search Power Bond. It also gives your Fusion Summons for the turn the ability to banish materials from the GY.

Therion "King" Regulus

The premier non-archetypal boss monster. Summons itself from hand by equipping a Machine from GY (like Core) and provides a flexible omni-negate.

Extra Deck Arsenal

Cyber Dragon Infinity

The deck's premier defensive monster. Provides a self-sustaining omni-negate by detaching a material. Can also absorb an opponent's attack position monster once per turn.

Cyber Dragon Nova

The stepping-stone to Infinity. Summoned with 2 Level 5 Machines (like Galaxy Soldier), it can revive a "Cyber Dragon" from GY. It's always used to rank-up into Infinity.

Chimeratech Rampage Dragon

The primary OTK enabler. On summon, destroys S/T. Can send 2 LIGHT Machines from Deck to GY (triggering Herz) to gain 2 additional attacks, for 3 attacks total.

Cyber Dragon Sieger

The damage multiplier. A Link-2 that can target a Machine you control (like Rampage) and give it 2100 ATK, pushing it into lethal OTK range.

Chimeratech Megafleet Dragon

A "Contact Fusion" board-breaker. Uses 1 "Cyber Dragon" + 1+ monsters in the Extra Monster Zone (from either field) as material. Removes Link bosses without targeting.

Chimeratech Fortress Dragon

The ultimate anti-Machine "Contact Fusion." Uses "Cyber Dragon" + 1+ Machine monsters (from either field) to absorb an entire Machine board into one monster.

This fundamental sequence shows how Cyber Dragon Core plus any monster for a discard (ideally Herz) establishes your primary omni-negate.

Cyber Dragon Core

1

Initiate & Search

Normal Summon Cyber Dragon Core. Activate its effect to search Cyber Repair Plant (CRP). Link Summon Salamangreat Almiraj using Core (puts Core in GY).

2

Activate & Extend

Activate CRP (live because Core is in GY) to search Galaxy Soldier from Deck to hand.

3

Generate Advantage

Activate Galaxy Soldier's effect, discarding Herz to Special Summon it. A chain forms:
Chain Link 1: Soldier searches a 2nd Soldier.
Chain Link 2: Herz searches Cyber Dragon.

Cyber Dragon Nova

4

Build the Lock

Activate the 2nd Galaxy Soldier, discarding Cyber Dragon to summon it. Overlay the two Level 5 Soldiers to Xyz Summon Cyber Dragon Nova, then use Nova's effect to rank-up into Cyber Dragon Infinity.

Typical Endboards

Defensive Stance (Go First)

Cyber Dragon Infinity
Missing: 10443957
  • Cyber Dragon Infinity: Provides the crucial omni-negate to disrupt the opponent's turn.
  • Set Cybernetic Overflow: A searchable trap that banishes "Cyber Dragon"s from GY (like Core and Herz) to destroy 2 cards.

Annihilation Mode (Go Second)

Chimeratech Rampage Dragon
Missing: 84058253
  • Chimeratech Rampage Dragon: Summoned via Power Bond (searched by Cyberdark Chimera) to be 4200 ATK.
  • Triple Attack: Rampage uses its effect, sending 2 Herz to GY, to gain 2 additional attacks for a total of 3 (12,600 damage).

Competitive Analysis

Strengths

  • "Contact Fusion" Checkmate: Can absorb an opponent's entire board (vs. Machines) or their key Link boss (vs. any deck) without targeting or destruction.
  • Explosive OTK Potential: Can consistently end the game in a single Battle Phase with Rampage Dragon.

Weaknesses

  • "Choke Points": Extremely vulnerable to hand traps. An 'Ash Blossom' on Core or Machine Duplication can end the turn.
  • Graveyard Hate: The entire engine relies on the GY (Core, Herz, CRP, Overflow). Floodgates like 'Macro Cosmos' are a game loss.

Key Spells & Tech

  • Cyber Emergency: The ultimate fixer. Searches Core, Galaxy Soldier, or any other missing "Cyber Dragon" monster.
  • Cyber Repair Plant: The payoff for the Core -> Almiraj play. Searches any LIGHT Machine, usually Galaxy Soldier.
  • Clockwork Night: A devastating tech card that turns all monsters on the field into Machines, enabling a full board wipe with Fortress Dragon.
