Main 44 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Ritual Summon Megalith boss monsters (Notrah Plura, Aratron, Bethor, Phaleg) and convert the board with ATK and Ritual-chain negation; Xyz and Link pressure from Ryzeal Detonator, Ryzeal Duo Drive and Gem-Knight Zirconia
- Turn 1 (going first): Search Megalith or Gem-Knight starters with Anastasis, Gem-Armadillo and Nepyrim, then Ritual Summon a Megalith boss with Phuloch, Phul or Hagith as the Ritual base
- Turn 2 (going second): Open on Ash Blossom and Maxx C to answer the first interaction, then rebuild the Ritual line from the GY with Megalith Emergence and Phuloch
- Recovery: Recover Megalith monsters from the GY through Phuloch, Phul and Hagith searches, then use Megalith Unformed to Ritual Summon again
- After siding: No side deck is registered, so no post-side plan can be assessed
Why it scores here
The deck is Illegal in OCG: it runs two Forbidden cards (Called by the Grave, Saryuja Skull Dread) and 2 copies of Ryzeal Detonator against a limit of 1, so it does not receive a normal Final Contextual score and is capped at 25 with a theoretical/structural-only read. Its searcher density is high (P(at least one searcher in a 5-card opening) ≈ 0.98, Inferred), which is what earns the consistency points, and its Ritual boss line gives reasonable closing ATK. Ash Blossom and Maxx C provide early hand-trap resilience. Popularity or meta share earned no points: there is no tournament or meta data, and card scores were not averaged. Because there are no recorded combos, floor and median output are scored on text alone and remain Inferred.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(>=1 searcher in 5) ≈ 0.98; archetype core 13 copies with P(open >=1) ≈ 0.84 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 58 | Ritual-dependent main deck with 4 Megalith/Gem-Knight three-copy staples; some dead conflicting starters across three archetypes (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No parseable combo boards; ceiling read from Megalith Notrah Plura and ritual chain text only (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No combo boards; median output unknown, scored conservatively from text (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Ash Blossom x2 and Maxx C give three hand-trap answers; no recursion beyond Megalith Emergence (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Megalith Phul, Hagith and Phuloch recover Ritual monsters from the GY; resource spend is high (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | Nine removal-text and nine negation-text cards including Notrah Plura and Aratron; no measured board data (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 55 | Three hand traps help against the going-second board, but there are few non-engine answers (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Notrah Plura 3700 ATK, Detonator 3000 ATK, Zirconia 2900 ATK; finish depends on Ritual setup (Verified stat / Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | Exact archetype purity only 30.5%; 41 of 59 copies are off-archetype, reducing coherence (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 50 | Extra Deck is 15 cards mixing Xyz, Link and Fusion, with a mixed Ryzeal and Gem-Knight base (Verified / Inferred) |
| D12 | Side Deck Adaptability | 15 | No side deck is registered, so no post-side adaptation exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link or dated meta sample; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multiple Ritual, Xyz and Fusion lines with several decision points per turn (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); engine conflicts (-4); Illegal cap (-11). Final formula: Illegal cap: 0.80*Structural(51) + 0.20*TournamentReliability(40) + ContextModifiers(-12) = 36.8, capped to 25 for Illegal status (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.98 · 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
- Searcher density (23 searcher-text cards) gives near-certain starter access
- Ritual boss ceiling (Notrah Plura 3700 ATK, Phaleg, Bethor) with recursion through Phuloch, Phul and Hagith
- Three hand traps and nine negation-text cards give early and mid-turn interaction
Weaknesses
- Illegal in OCG: two Forbidden cards and one Limited card over its copy limit
- Low archetype purity (30.5%) with three competing engines
- No side deck and no combo data, so floor and matchup reads are unsupported
Critical choke points
- Ritual monster in hand plus Megalith Unformed or Anastasis to start the Ritual line
- Dependence on Forbidden or over-limit cards for the Extra Deck and negation
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave and Saryuja Skull Dread | Legal OCG replacements such as an additional Megalith removal or negation card | Forbidden cards make the list illegal; removing them is required before any normal score |
| 2 | One copy of Ryzeal Detonator | A legal Rank 4 Xyz or Link staple | The second copy exceeds the Limited copy limit of 1 |
| 3 | Off-archetype Ryzeal and Gem-Knight staples that do not complete a Megalith line | More Megalith Ritual monsters or Ritual spells | Raises archetype purity above 30.5% and reduces engine conflicts |
| 4 | None | A side deck of 8 to 15 cards | The deck has no side deck, so it has no post-side plan |
Evidence & confidence
- Verified: Illegal status: Called by the Grave and Saryuja Skull Dread are Forbidden; Ryzeal Detonator runs 2 copies against a limit of 1; Main 44 and Extra 15 satisfy the OCG size rules; Archetype purity 30.5%; searcher text count 23
- Observed: No parseable combo boards exist, so no measured floor, median or ceiling is available
- Inferred: Opening-hand starter access (≈0.98) and core-group access (≈0.84) from hypergeometric estimates; Strategy classification as Midrange from the Ritual and Extra Deck mix; Going-first and going-second estimates
- Provisional: Meta Power (null) and Matchup coverage (D13) because no dated metagame sample exists
- 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 exists in YGOVN No side deck registered, so D12 has no post-side data Meta Power is Provisional unless a dated metagame sample is supplied
