Legality
Main 60 / Extra 15 / Side 15 — status: Legal.
Identity & game plan
- Win condition: Ritual summon large Megalith/Mitsurugi monsters and control board with negations; Beatdown with high-ATK EARTH/Rock bosses
- Turn 1 (going first): Use Pre-Preparation/Anastasis to search ritual pieces, establish Megalith Aratron/Notrah or Mitsurugi Murakumo with negation
- Turn 2 (going second): Side in Dark Ruler No More/Dimensional Barrier, break board with S:P Little Knight/Evilswarm Exciton
- Recovery: Megalith Phul/Hagith recycle rituals, Block Dragon search Rocks, Mulcharmy draw
- After siding: Bring in hand traps, board breakers, and floodgate-like barriers to adapt to meta
Why it scores here
This 60-card Megalith/Mitsurugi/Magnet mash-up opens with high probability of seeing a core piece (P≈0.97) but individual starters are diluted, yielding moderate consistency rather than explosive turn-one boards. The deck's ceiling includes layered negations from Megalith Notrah Plura, Aratron, and Mitsurugi Murakumo plus Baronne de Fleur, but the median output is a single ritual boss with sparse interaction. No combo telemetry was supplied, so floor/median/ceiling are inferred from card text, not averaged from card scores. Popularity of archetype cores does not by itself raise the score; the deck's size and engine conflict cap its reliability.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 65 | Archetype-core group (29 copies) yields P(open≥1)=0.9689 but individual 3-of starters only P=0.2333 in 60-card deck (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 60-card list with 19 singleton cards and multiple dead rituals increases brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 75 | Megalith Notrah Plura and Mitsurugi Murakumo provide board wipes and negation, suggesting high ceiling (Inferred) |
| D4 | Combo Floor & Median Output | 55 | Without combo records, median expected to be single ritual summon with minimal follow-up (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Multiple ritual lines (Megalith discard, Mitsurugi tribute, Magnet fuse) give some route redundancy (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 65 | Pre-Preparation, Anastasis, Mulcharmy, and Block Dragon enable card draw and Rock recursion (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | Interaction density from 13 negation-text cards including boss rituals and Baronne/Naturia extra deck (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 45 | Main deck lacks dedicated board breakers; relies on side Dark Ruler No More and Dimensional Barrier (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | Boss monsters like Notrah Plura (3700) and Murakumo (3200) provide strong offensive pressure (Verified) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 60-card main with 34 distinct cards reduces compactness and raises garnet chance (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 65 | Extra deck covers fusion/synchro/xyz/link toolbox with generic and archetype bridges (Verified) |
| D12 | Side Deck Adaptability | 70 | Side deck of 15 includes hand traps, Dark Ruler, Barrier, Crossout for best-of-3 adaptation (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame sample; matchup fit unconfirmed (Provisional) |
| D14 | Pilotability & Error Tolerance | 55 | Multi-engine ritual play with many decision points lowers error tolerance (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 62, Going First ≈ 65, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Oversized main deck (-3); Engine redundancy (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- High chance to open a core piece
- Layered negation from rituals and extra deck
- Strong side deck for adaptation
Weaknesses
- 60-card deck reduces consistency
- No combo telemetry; actual lines unverified
- Weak going-second main deck plan
Critical choke points
- Reliance on ritual summon pieces that can be hand-trapped
- Diluted starter count in 60-card list
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Some singleton off-archetype cards | More copies of Megalith Anastasis or Pre-Preparation | Improve consistency in 60-card frame |
Evidence & confidence
- Verified: Legality status; Extra deck breakdown; Side deck list; Card text excerpts
- Observed: No parsed boards
- Inferred: Consistency probabilities; Brick risk; Combo ceiling from text
- Provisional: Matchup fit without metagame
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
