Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 50 |
| Going First | 52 |
| Going Second | 48 |
| Meta Power | provisional |
| Tournament Reliability | 45 |
- Primary strategy: Midrange

- Format: master-duel
Legality
Main 44 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Ogdoadic/Reptilianne boards that lead with Nephilabyss, Aron, Amunessia or Ogdoabyss and close with Chaos Angel, Psychic End Punisher, Avramax or Borrel Savage Dragon; Bystial and Rose Dragon extra-deck boards via Bystial Lubellion/Baldrake and Black Rose Dragon
- Turn 1 (going first): Open a Reptilianne Coatl or Lamia (Tuner) plus Ogdoadic Daybreak/Water Lily to reach a Synchro or Link summon, using hand traps (Ash Blossom, Effect Veiler, Maxx C) to protect the first line
- Turn 2 (going second): Hold hand traps (7 in deck) to negate the opponent's first summon, then rebuild through Ogdoadic graveyard revivals (Nunu, Nauya, Nephilabyss) and Offering to the Snake Deity or Infinite Impermanence on the board
- Recovery: Graveyard revival of Ogdoadic and Reptilianne monsters (Nunu, Nephilabyss, Aron, Amunessia) and Reptilianne Spawn/Ramifications to rebuild from hand and Deck
- After siding: No side deck is registered (0 of 15 slots used), so there is no evidenced post-side plan
Why it scores here
This list is Illegal because it runs two copies of Maxx "C" against a one-copy Limited limit, so the score is capped at 30 and the result is structural only. Structurally it sits near 50: the 9-copy Reptilianne/Ogdoadic core has about a 70% chance of at least one starter in an opening 5 (Inferred), and seven hand traps plus Offering to the Snake Deity give it real interaction density. Closing power comes from Nephilabyss, Aron, Chaos Angel and Psychic End Punisher. The score is held down by three overlapping engines (Ogdoadic, Reptilianne and Bystial), only 13 of 44 main cards carry the exact Reptilianne name, and 14 of 15 Extra Deck slots are distinct cards with no shared route. No combos, guides, tournament record or side deck were supplied, so the floor and median are inferred from text only. The score was not produced by averaging card scores or by the archetype's popularity.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(at least one of the 9-copy archetype core in a 5-card opening hand) ≈ 0.70; engine split across Ogdoadic and Reptilianne lowers reliability (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Many single-copy cards and two engines in one hand; hand traps and Daybreak/Water Lily give some functional hands, but brick risk is high (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | Ceiling from Vaskii/Ogdoabyss/Amunessia boards plus Synchro/Link extra options; no recorded boards to measure (Inferred, semantic read) |
| D4 | Combo Floor & Median Output | 40 | No parseable recorded boards, so the median output is unmeasured and only estimated from text (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Seven hand traps and graveyard revival (Nunu, Nephilabyss, Aron) give several independent recovery routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Recursion and search from Ramifications, Nauya and Ogdoadic text, but the Extra Deck spends many resources on Link and Synchro summons (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Offering to the Snake Deity, Infinite Impermanence, Maxx C, Ash Blossom, Effect Veiler, Baronne and Psychic End Punisher give layered interaction (Verified text, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 55 | Vaskii, Ogdoabyss, Amunessia and Baronne answer established boards; going-second split not recorded (Inferred) |
| D9 | Offensive Pressure & Closing Power | 68 | Multiple 2500+ ATK bosses (Nephilabyss 2200/3100, Aron 2500/2800, Chaos Angel 3500, Psychic End Punisher 3500) (Verified stats) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 44 main cards with 26 distinct names and 22% exact-archetype purity (46 off-archetype copies); low compactness (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 50 | 15 Extra slots with 14 distinct cards across Link, Synchro and Xyz; wide coverage but low cohesion (Verified composition) |
| D12 | Side Deck Adaptability | 10 | No side deck registered (0 of 15 cards); no post-side adaptability can be evaluated (Provisional) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; format fit cannot be measured (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Three engines and about 14 distinct Extra Deck cards create many decision points; complex to pilot (Inferred) |
How the score was computed
Strategy profile: Midrange profile; Toolbox used as secondary context only. Structural ≈ 50, Going First ≈ 52, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-6); engine conflicts (-4); illegal_list_cap (-9). Final formula: No reliable metagame: 0.80*Structural(50) + 0.20*TournamentReliability(45) = 49, less modifiers (−10) = 39, then capped at 30 because the list is Illegal (theoretical/structural-only)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.31 · 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
- Layered hand-trap and backrow interaction (7 hand traps, Offering to the Snake Deity)
- High-stat closing bosses (Chaos Angel 3500, Psychic End Punisher 3500, Nephilabyss 2200/3100)
- Graveyard recursion for the Ogdoadic and Reptilianne cores
Weaknesses
- Illegal list: Maxx "C" run 2 copies against a 1-copy limit
- Low archetype purity (22%) and three competing engines
- No side deck registered
Critical choke points
- Reliance on the 9-copy Ogdoadic/Reptilianne core for the first line
- Single-copy Vaskii and Bystial extra-link routes are not redundant
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One Maxx "C" | Nothing required to become legal | Brings the list to the 1-copy Limited limit; the deck then becomes legal and can receive a normal score |
| 2 | Off-archetype Bystial single-copy cards | Additional copies of the core Reptilianne/Ogdoadic cards already in the deck | Raises archetype purity and the chance the core line is live on T1 (Inferred) |
Evidence & confidence
- Verified: Main 44 / Extra 15 / Side 0 sizes within master-duel limits; Maxx "C" 2 copies vs legal limit 1 (Limited); Card stats and text for all listed cards; Hypergeometric probabilities from the resolved list
- Inferred: Starter consistency and brick rate from hypergeometric estimates and card text; Ceiling and interaction quality from card text; Going-first and going-second strength
- Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (no tournament link); Side deck adaptability (no side deck registered)
- Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry for going-first, going-second, matchup or brick rate Meta Power provisional without a dated metagame sample No side deck registered
