Legality
Main 50 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Labrynth and Plunder Patroll board presence converted into 2500-3000 ATK Level 8 bosses (Lady Labrynth, Lovely Labrynth, Nibiru, AA-ZEUS) and Plunder Patroll Extra Deck attackers; Synchro and Link Extra Deck pressure from Plunder Patrollship Brann, Chaos Angel and Blackbeard
- Turn 1 (going first): Set Normal Traps (Welcome Labrynth, Big Welcome Labrynth) and Normal Summon Labrynth/Plunder Patroll monsters to reach a Level 8 boss, backed by Infinite Impermanence and Ash Blossom for interaction
- Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Evenly Matched and Maxx C through the opponent's first turn, then Special Summon from the hand via Plunder Patroll or Labrynth effects to rebuild the board
- Recovery: Recover from the GY through Labrynth Stovie Torbie, Labrynth Chandraglier and Labrynth Cooclock, plus Plunder Patroll searches from Shipyarrrd and Plunder Patrollship Moerk
- After siding: Not applicable: master-duel side deck size is 0 in this list, so no post-side plan can be evidenced
Why it scores here
The deck's score comes from the system: a Labrynth core of 20 copies gives a 0.93 probability of at least one core card in a 5-card opening hand (Inferred), and the Labrynth and Plunder Patroll Extra Deck lines reach Level 8 and 2500-3000 ATK bosses through several overlapping routes. Interaction is dense for a Midrange list, with 13 hand traps and 10 negation-text cards, and that density is what keeps the deck alive through disruption and gives it a reasonable going-second hand. Consistency is held back by 47 off-archetype copies, 11 singleton slots, and a 6.7% proxy brick rate, and the combo floor and median could not be measured because no boards were recorded. The score is not earned from Labrynth being a popular archetype or from averaging card scores. The deck is Illegal (Forbidden Called by the Grave and 3 copies of Maxx C against a limit of 1), so the score is structural and theoretical only and is pulled down by a -12 banlist modifier.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(at least one archetype core card in opening hand of 5) ≈ 0.93 across 20 Labrynth/Plunder Patroll-linked core copies; starter access is strong but the core is split across two sub-archetypes (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Copy histogram is 9 three-copy, 6 two-copy and 11 single-copy distinct main cards; 13 hand traps and 16 tech slots create some dead-in-hand risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No parseable boards in combo data, so ceiling is read from card text only: Level 8 boss plus Plunder Patroll Extra Deck summons (Inferred) |
| D4 | Combo Floor & Median Output | 40 | combo data has zero scored combos, so the median is unmeasured and set low on the card-text read of a hand-trap-heavy shell (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | 13 hand traps and 10 negation-text cards give several independent answers, and GY recursion (Stovie Torbie, Chandraglier, Cooclock) adds rebuild routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Recursion and search density are high (13 searcher-text cards, GY revival from several monsters), but the deck spends hand cards on Normal Trap activations (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Infinite Impermanence, Evenly Matched, Ash Blossom, Nibiru, Crossout Designator and Dimensional Barrier give layered end-board interaction; Called by the Grave is Forbidden and cannot count (Verified text, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 55 | Hand-trap coverage on the going-second turn is high (P(at least one hand trap in hand of 6) ≈ 0.85), but there are few dedicated board breakers in the Main Deck (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Level 8 bosses at 2900-3000 ATK plus Chaos Angel at 3500 ATK give closing power, but only 1 copy of Chaos Angel is run and it is not in the core (Verified stat, Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 50 Main Deck cards across 26 distinct names, 47 off-archetype copies, and a Forbidden card take up slots, which lowers compactness (Verified composition, Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra Deck cards across 9 distinct names cover Synchro, Link, Xyz and Fusion access with several Plunder Patroll options; flexibility is reasonable (Verified composition) |
| D12 | Side Deck Adaptability | 30 | No side deck is present (master-duel side size is 0 in this list), so post-side adaptability cannot be evidenced (Provisional) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no dated meta sample; the archetype is present in usage statistics but its format share is unknown (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Multi-step Labrynth Normal Trap sequencing and Plunder Patroll Extra Deck activations have many decision points, but the basic plays are readable (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: 0.80*Structural(52) + 0.20*TournamentReliability(40) = 49.6 before modifiers; Meta provisional; -12 banlist modifier -> 37.6, rounded to 38. Illegal list: structural/theoretical only.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Archetype core of 20 copies gives high starter access (Inferred)
- 13 hand traps and 10 negation-text cards give layered interaction (Inferred)
- Level 8 bosses and Plunder Patroll Extra Deck pressure give closing power (Verified stat, Inferred)
Weaknesses
- Illegal list: Forbidden card and over-limit Maxx C (Verified)
- Two sub-archetypes split the core and add off-archetype copies (Verified composition)
- No recorded combos, so floor and median cannot be measured (Verified data gap)
Critical choke points
- Ash Blossom and Infinite Impermanence are the main interaction, and their loss leaves little answer to a going-second board (Inferred)
- Level 8 boss access depends on Normal Trap activations, so one missed Labrynth trap stalls the plan (Inferred)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave (2 copies) | A legal removal or negation card in its slot | Forbidden in master-duel, so the list cannot be legal while it runs |
| 2 | Maxx C (2 of 3 copies) | A legal copy-limited-safe card | Limited to 1 copy; the other copies make the list illegal |
Evidence & confidence
- Verified: Legality: Called by the Grave Forbidden x2, Maxx C Limited x3 over limit 1 (Verified); Main 50 and Extra 15 are within master-duel size rules (Verified); Card text and banlist status for all 37 distinct cards (Verified); Usage stat: Labrynth Cooclock, Maxx C and Big Welcome Labrynth at 84.6% inclusion (Verified)
- Inferred: Consistency from hypergeometric odds (Inferred); Interaction density and going-second hand-trap coverage from text (Inferred); Level 8 boss routes and Plunder Patroll Extra Deck lines (Inferred)
- Provisional: Meta power null; no dated meta sample; Tournament reliability and format fit provisional without tournament data
- Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry exists in YGOVN Meta Power provisional unless a dated metagame sample is supplied Deck title is null, so the name is unknown
