Cyber Dragon Deck #764830 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion/Link boards led by Chimeratech Rampage Dragon, with Power Bond and Polymerization as the big-board conversion (guide claim, Inferred); Xyz/Link pressure from Cyber Dragon Infinity, Cyber Dragon Nova and Cyber Dragon Sieger when the Cyber Dragon engine is live
• Turn 1 (going first): Normal Summon Cyber Dragon Core to search a Cyber Spell/Trap, extend with Cyber Emergency or Cyberdark Realm, and build toward a Link or Fusion board
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Droll and Lock Bird, Maxx C) to answer the opponent's first turn, then Cyber Dragon Core or Nachster into the Link/Fusion route
• Recovery: Recursion through Cyber Dragon Herz and Nachster name-change and GY effects, Cyberdark Claw GY recovery of a Cyberdark monster, and Clockwork Night GY banish-to-search
• After siding: None. The deck runs 0 side cards in a format that allows up to 15, so there is no post-side plan.

Why it scores here

The deck reliably opens a live engine on the first turn: three Cyber Dragon Core copies normal-summon into a Cyber searcher, and the 21 searcher-text cards give a 98% chance of at least one searcher in the opening five (Inferred from hypergeometric estimates). Eight hand traps and nine removal-text cards give it a real answer to the opponent's first turn, with a 76% chance of at least one hand trap in a going-second six-card hand, though that same density is the main brick risk, since a lone hand trap in hand is often dead. Its conversion ceiling is high on paper (Chimeratech Rampage Dragon, Power Bond, Cyber Dragon Infinity), but no recorded boards exist, so floor and median are inferred from guide text and not measured. The score is not earned from Cyber Dragon's popularity, the guides' claim that the deck is weak in the current meta, or any averaging of card scores; the sub-archetype split across Cyber, Cyberdark, Mulcharmy, Therion and Chronomaly lowers coherence and is penalised. With no side deck and no metagame sample, Meta Power stays provisional and the Final score rests on structural strength alone.

Dimension scores

How the score was computed

Strategy profile: Combo primary; Midrange used as a secondary read only for the Toolbox/midrange hand-trap context, not weighted. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine conflicts / sub-archetype split (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null); 0.80*59 + 0.20*50 = 57.2, then -3 modifier = 54

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ 0.24 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Legal list with every Limited/Semi-Limited card at its legal copy cap
• Dense searcher text (21 cards) gives a 98% chance of at least one searcher in the opening five
• Eight hand traps and nine removal-text cards give real answers to both going-first and going-second boards
• Full Extra Deck (15) with Fusion, Link and Xyz boss options and Power Bond/Polymerization access

Weaknesses

• Exact-name Cyber Dragon purity is only 27.3%; the list spreads across several sub-archetypes
• Hand-trap-heavy hands brick easily; a single hand trap in hand is often dead (guide text)
• No Side Deck in a format that allows up to 15
• No recorded boards, so the ceiling and median are text-only inference

Critical choke points

• Cyber Dragon Core (3 copies) is the main normal-summon starter; without it the opening hand may lack a searcher engine
• Power Bond and Chimeratech Rampage Dragon need Cyber Dragon / Machine materials that must already be on the field or in the GY
• Cyber Dragon summon conditions (Nachster, Cyber Dragon) require an opponent monster on the field

Evidence & confidence

• Verified: Legality: Legal in master-duel, 40 Main / 15 Extra / 0 Side within size rules; Restricted cards: Crossout Designator (Limited, 1), Maxx C (Limited, 1), Droll and Lock Bird (Semi-Limited, 2), all within legal copies; Composition: 24 distinct Main, 12 distinct Extra, exact-name purity 27.3%, role tag counts (hand trap 8, removal-text 9, searcher-text 21); Usage stats: 16 of 25 core cards present (64%)
• Inferred: P(>=1 Cyber Dragon Core in hand5) = 0.338; P(>=1 searcher-text card in hand5) = 0.982; P(>=1 hand trap in hand6, going second) = 0.764 (hypergeometric); Strategy classification as Combo with Midrange/Toolbox secondary reads, from card text and the Extra Deck mix; Recovery and interaction density read from card text, not board data; Floor and median are inferred from guide text, not measured
• Provisional: Meta Power is null; matchup fit (D13) and the guides' claim that the deck is below meta strength are unverified without a dated metagame sample
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry: going-first/second split, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample deck.title is null; the deck is identified only by archetype and id Guides are Vietnamese community posts; their OTK and strength claims are not verified
