  • Primary strategy: Combo

  • Format: ocg

Legality

Main 53 / Extra 17 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Link Summon Cyberse Link monsters (Firewall Dragon Singularity, Firewall Dragon Darkfluid, Allied Code Talker @Ignister) and close with 2300+ ATK boards; Ritual and Synchro or Fusion Cyberse extra-deck lines (Code Igniter, Firewall Saber Dragon, Cyberse Code Magician through Cyberse Sage)
  • Turn 1 (going first): Open with Achichi, Pikari, Backup, or Cynet Mining to search the next @Ignister or A.I. piece, then build a Link-3 to Link-5 board. Interaction is held in hand for the opponent's turn.
  • Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Effect Veiler, Droll and Lock Bird, Infinite Impermanence, Nibiru) to break the opponent's first line, then recover through Ignister searches and Link summons
  • Recovery: Searchers and recursion from the GY (Dotscaper, Backup, Ignister Land, Gatchiri) rebuild a starter after a single disruption. This relies on the 16 searcher-text cards.
  • After siding: Not applicable. The deck has no Side Deck (side_count 0), so there is no post-side plan.

Why it scores here

The deck is Illegal (Link Decoder is Forbidden and the Extra Deck is 17 against a 15 maximum), so the score is a theoretical, structural-only read capped at 30 under rubric Step 2. Structural power comes from searchers and starters that are reasonably accessible (P of at least one archetype-core card in a 5-card hand is about 0.92, and about 0.85 for searcher-text cards), a large hand-trap and negation suite (13 hand traps, 13 negation-text cards), and strong Link-5 and Link-6 closers. The score reflects the deck as a system: weak archetype coherence (only 4.3 percent exact-name purity and 67 off-archetype copies across Code Talker, Mulcharmy, Cyber and Harpie), no sideboard, no combo corpus, and a heavy Limited/Forbidden exposure. Archetype popularity and the 56 percent core presence in usage stats were not counted as power, and card scores were not averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 62 Archetype-core group P(at least one in hand of 5) = 0.92 and searcher-text group 0.85; starters are 3-copy at P=0.26 each (Inferred)
D2 Opening-Hand Quality & Brick Management 50 Proxy brick rate about 0.08 for the core group; 67 off-archetype copies and mixed sub-archetypes raise conflict risk (Inferred)
D3 Combo Conversion & Ceiling 45 No parseable combos; ceiling is a text-only read of Link-5/6 chains through Ignister and Firewall extra monsters (Inferred)
D4 Combo Floor & Median Output 40 No parseable combos; median output cannot be measured, so the floor is set conservatively (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Multiple independent starters and 16 searcher-text cards provide redundant lines after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 55 Searchers and GY recursion (Dotscaper, Backup, Gatchiri) help rebuild; Link material costs are heavy (Inferred)
D7 End-Board & Interaction Quality 75 13 hand traps, 13 negation-text cards and 14 removal-text cards; several are Limited (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 60 Hand traps and Nibiru/Dark Ruler give going-second answers, but no measured going-second split exists (Inferred)
D9 Offensive Pressure & Closing Power 70 Extra Deck closers at 3000 to 5000 ATK (Perfectron 5000, Singularity 3500, Darkfluid 3000) (Verified stats)
D10 Main Deck Efficiency & Flexibility 45 53 Main Deck cards with 21 tech and 13 hand-trap slots; 67 off-archetype copies lower coherence (Inferred)
D11 Extra Deck Efficiency & Coverage 40 17 Extra Deck cards with 14 Links; 2 over the limit and Link Decoder Forbidden (Verified)
D12 Side Deck Adaptability 10 No Side Deck (side_count 0); no post-side data exists (Provisional)
D13 Matchup Coverage & Format Fit 50 No dated metagame or tournament link; archetype share unknown (Provisional)
D14 Pilotability & Error Tolerance 35 Multiple chained Ignister, Code Talker and Firewall effects with many decision points raise pilot load (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 53.7, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-3); engine conflicts (-2). Final formula: Uncapped: 0.80*53.7 + 0.20*45 = 52.0 (Meta provisional). Illegal deck per rubric Step 2: capped to 30 as a theoretical, structural-only score.

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.26 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Dense hand-trap and negation suite (13 hand traps, 13 negation-text cards)
  • Searcher density (16 cards) gives redundant starter access
  • High-ATK Link and Synchro closers (Perfectron 5000, Singularity 3500, Darkfluid 3000)

Weaknesses

  • Illegal list: Link Decoder Forbidden and Extra Deck over by 2
  • Low archetype purity (4.3 percent exact name) and mixed sub-archetypes
  • No Side Deck, so no post-side plan
  • Heavy reliance on Limited cards

Critical choke points

  • Ignister starter cards (Achichi, Pikari, Backup) at about 26 percent each in a 5-card hand
  • Extra Deck legality, which must be fixed before any normal score applies
Priority Remove Add Reason
1 Link Decoder A legal Link-1 Cyberse extra-deck monster (none named in the evidence) Clears the Forbidden copy-limit violation
2 Two Extra Deck cards of lowest role coverage (not determinable from the evidence) No replacement needed Brings the Extra Deck to the OCG maximum of 15
3 Off-archetype Code Talker or Mulcharmy copies Archetype-core Ignister or Firewall cards Raises purity and engine coherence

Evidence & confidence

  • Verified: Legality: Illegal, Link Decoder Forbidden with 1 copy, Extra Deck 17 vs 15; Card text, stats and banlist status for each distinct card; Composition counts and archetype purity
  • Inferred: Hypergeometric starter, core and searcher-group probabilities; Brick rate and archetype-conflict estimates; Interaction and Link-closer quality from text
  • Provisional: Meta Power and matchup fit (no dated metagame or tournament link); Going-first and going-second power without win data
  • 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 and going-second splits are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck; post-side evaluation is not possible
