Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

  • Win condition: Link-5 and Link-4 boards (Perfectron Hydradrive Dragon, Firewall Dragon Darkfluid, Maliss Hearts Crypter) built from Cyberse Link chains, with Maliss and @Ignister engines feeding the Extra Deck; Maliss banish-recursion and Mulcharmy card advantage grinding the opponent out of resources
  • Turn 1 (going first): Open a Cyberse starter (Backup @Ignister, Maliss White Rabbit, or Mulcharmy) on T1, extend into a Link-2/3 via Maliss or Ignister searches, and hold Ash Blossom, Ghost Belle, or Maxx C for interaction
  • Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Droll & Lock Bird, Infinite Impermanence, Maxx C) to answer the opponent's first summon, then rebuild a Link board from the GY
  • Recovery: Mulcharmy and Maliss GY or banish recursion, and Maliss Link monsters that re-summon Maliss monsters from the GY
  • After siding: Not assessable: the deck has no Side Deck (side_count 0), so there is no post-side plan in the evidence

Why it scores here

The deck is illegal in OCG: it runs three Forbidden or over-limit cards (Triple Tactics Talent, Link Decoder, Albion the Branded Dragon) and three Maliss in Underground against a limit of 2. Its structural read is therefore theoretical only. Its strength is a dense interaction package: 11 hand traps, 12 negation texts, and 27 removal texts, which earns the interaction and going-second dimensions. Engine access is split across three archetype cores (Mulcharmy, Maliss, @Ignister), with about 83% odds of at least one core card in a 5-card opening hand, so consistency is only moderate. No combo boards were recorded, so the ceiling and median are text-based inferences. Archetype popularity earned no points, and card scores were not averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 55 P(>=1 of 16 archetype-core cards in 5-card opening hand) ≈ 0.83, but spread across three engines; starter lines not verified (Inferred)
D2 Opening-Hand Quality & Brick Management 50 Brick proxy ≈ 0.17 for the core group; many dead-on-arrival parts (Link-only Extra, 11 hand traps) and no Side Deck to fix it (Inferred)
D3 Combo Conversion & Ceiling 60 Link-3 to Link-5 chains (Maliss Hearts Crypter, Firewall Dragon Darkfluid, Perfectron Hydradrive Dragon) from card text; no recorded boards (Inferred)
D4 Combo Floor & Median Output 45 No combos_evidence rows; floor depends on hand-trap and Mulcharmy draw without a verified median (Inferred)
D5 Interruption Resilience & Route Redundancy 60 Two independent resources (Maliss banish-recursion, Mulcharmy draws) plus 11 hand traps; redundancy from text only (Inferred)
D6 Resource Economy, Recovery & Grind 55 Mulcharmy draw effects, Maliss recursion, Pot of Sloth and Maxx C; no netCardAdvantage data (Inferred)
D7 End-Board & Interaction Quality 75 12 negation and 27 removal text hits; Solemn Judgment, Ash Blossom, Ghost Belle, Infinite Impermanence, Droll & Lock Bird (Verified text, Inferred quality)
D8 Going-Second & Board-Breaking Power 70 Hand-trap density gives about 0.76 odds of a hand trap in a 6-card going-second hand (Inferred)
D9 Offensive Pressure & Closing Power 55 Firewall Dragon Darkfluid (ATK 3000) and Perfectron (ATK 5000) are big closers, but both need a Link set-up (Verified stats, Inferred)
D10 Main Deck Efficiency & Flexibility 50 55 main cards over 34 distinct names; three copies of several engine cards and 27 zero-level cards (Verified composition)
D11 Extra Deck Efficiency & Coverage 60 15 Extra slots: 12 Link, 2 Fusion, 1 Synchro, with Forbidden cards among them (Verified)
D12 Side Deck Adaptability 10 No Side Deck (side_count 0); no post-side plan to score (Verified)
D13 Matchup Coverage & Format Fit 40 No tournament link and no dated meta sample; archetype share unavailable (Provisional)
D14 Pilotability & Error Tolerance 40 Three archetype engines and many Link-summon sequencing decisions; high decision load (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_deck (-4). Final formula: Illegal cap: normal formula not applied. Structural 56 (Combo profile); 0.80*56 + 0.20*45 = 53.8, less modifiers -12, then capped to 25 as theoretical/structural-only because the deck is illegal in OCG

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.83 · key two-card combo ≈ — · full-brick estimate ≈ 0.17 (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 package (11 hand traps, 12 negation texts) that performs well going second
  • Multiple independent recursion routes (Maliss banish recursion, Mulcharmy draws) for resilience
  • High-ATK Link closers (ATK 3000 and 5000) available from the Extra Deck

Weaknesses

  • Illegal in OCG: three Forbidden cards and one over-limit card, so the list cannot be played as built
  • Three engines (Maliss, Mulcharmy, @Ignister) compete for the same main-deck slots and the same Extra Deck links
  • No Side Deck and no side-deck plan

Critical choke points

  • Link monsters are the only route to a board, so Link-summon disruption ends most lines
  • Forbidden cards (Link Decoder, Albion) are a logic gap in the list, not a tuning choice
Priority Remove Add Reason
1 Triple Tactics Talent, Link Decoder, Albion the Branded Dragon Legal Link or engine cards from the same archetype core Forbidden cards make the list illegal; this is the first fix before any power read is meaningful
2 One copy of Maliss in Underground A legal Maliss or @Ignister engine card Brings the Semi-Limited copy count to 2 and reduces dead engine copies
3 Off-engine tech cards (e.g., Terraforming, Gold Sarcophagus) A Side Deck of 5–15 cards A side deck gives post-side adaptability, which the current list does not have

Evidence & confidence

  • Verified: Main deck 55 cards, Extra 15, Side 0; within OCG size rules; Forbidden: Triple Tactics Talent, Link Decoder, Albion the Branded Dragon; Maliss in Underground over Semi-Limited limit; 11 hand traps, 12 negation texts, 27 removal texts from text_role_hints; Extra Deck is 12 Link, 2 Fusion, 1 Synchro
  • Inferred: Core-group opening-hand access ≈ 0.83; Hand-trap odds in a 6-card going-second hand ≈ 0.76; Link-5 and Link-4 board potential from card text; Interaction quality (D7) from negation and removal text
  • Provisional: Meta Power (null) and matchup fit (D13) without a dated meta sample
  • Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inferences No tournament link: archetype meta-share and per-pilot record unavailable No win-rate telemetry for going-first, going-second, or matchups No Side Deck, so post-side performance cannot be evaluated Deck title is null in the export
