Cyber Dragon Deck #770090 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: ocg

Legality

Main 46 / Extra 14 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Theoretical only: Cyber Dragon fusion and Xyz boards (Cyber End Dragon, Cyber Eternity Dragon, K9-X Werewolf, Cyber Dragon Nova) converting from Cyber Dragon summons; no recorded boards to confirm it.; Chimeratech Fortress/Rampage/Megafleet Dragon boards and Heosvarog recursion, all Inferred from card text.
• Turn 1 (going first): Normal Summon Cyber Dragon Core or Cyber Dragon Nachster, search a Cyber spell (Cyber Emergency, Cyberdark Realm) and reach a Fusion or Xyz board. Cyber Dragon and Cyber Dragon Herz need an opponent monster to Special Summon, so the opening is conditional.
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence and Maxx C for the opponent's first activation, then use K9 and Cyber Dragon summons on the response window. The Forbidden K9-04 and Spell Canceller are illegal in this list and cannot be relied on.
• Recovery: Cyberdark Wurm, Cyber Dragon Nachster and Cyber Dragon Herz recover Cyber Dragons from the GY; Cyber Dragon Nova banishes Cyber Dragons from hand or field. Inferred from text; no recorded boards.
• After siding: Not evaluable: the deck runs no Side Deck (side_count 0), so there is no post-side plan.

Why it scores here

The list is illegal in OCG: it runs Forbidden K9-04 Noroi and Spell Canceller, and two copies of Limited "A Case for K9" against a limit of one. Under the rubric it is capped at 30 and the structural read below is theoretical only. As a system it has a real engine (Cyber Dragon summons, a Fusion and Xyz extra deck, 18 searcher effects, 6 hand traps), and the 0.80 probability of at least one archetype-core card in the opening five gives it a usable opening. Its score is not raised by Cyber Dragon popularity or by any average of card scores. Brick risk is high: 26 of 31 distinct main-deck cards are singletons or doubles, purity by exact name is 21.7%, and the deck has no Side Deck and no combo or tournament data. The score is lowered by the banlist exposure and the missing side.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-3). Final formula: Illegal list: theoretical/structural-only. Unrounded 0.80*52.4 + 0.20*45 = 50.9; modifiers -11 give 39.9; capped at 30 for illegality. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Real Cyber Dragon engine with searchers and GY recursion
• Layered hand traps and negation (Ash Blossom, Infinite Impermanence, Maxx C)
• Strong closing bosses in Extra Deck (Cyber End Dragon, K9-X Werewolf, Jizukiru)

Weaknesses

• Illegal list: Forbidden and over-limit cards in the main deck
• Low archetype purity (21.7% exact name) with many off-theme K9, Cyberdark, Forbidden and Therion cards
• No Side Deck and no combo or tournament evidence

Critical choke points

• Cyber Dragon summons require an opponent monster on the field
• K9 summons require the opponent to hold 2+ cards in hand
• Any illegal card is removed at the banlist check before play

Recommended changes

Evidence & confidence

• Verified: Legality violations: K9-04 Noroi (Forbidden), Spell Canceller (Forbidden), "A Case for K9" over Limited limit; Main 46 and Extra 14 are within OCG size rules; Side 0; Exact-name archetype purity 21.7%
• Inferred: Archetype-core hand-five probability ≈ 0.80; Hand-trap hand-six probability ≈ 0.59; Cyber Dragon engine and hand-trap ceiling from card text
• Provisional: Tournament and meta-share relevance (D13) and Meta Power (null)
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record absent Passcode 10443957 in CardIDList could not be resolved to a card and was counted as main No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power provisional; no dated metagame sample supplied
