Legality
Main 45 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).
Identity & game plan
- Win condition: Fiendsmith Fusion/Link boards (Fiendsmith's Desirae, Fiendsmith's Lacrima) and Mitsurugi Ritual boss monsters (Ame no Murakumo no Mitsurugi, Ruler of the End of the World); Link and Xyz pressure through Fiendsmith's Sequence-style recursion (both absent from the list; Dyna Mondo and Garura are the closest present options)
- Turn 1 (going first): Search with Fiendsmith Engraver and Fiendsmith's Tract into Lacrima the Crimson Tears or a Mitsurugi Ritual line, then go to an Extra Deck boss
- Turn 2 (going second): Hand trap (Ash Blossom, Droll & Lock Bird, Nibiru) to break the opponent's first board, then rebuild through the Mitsurugi Ritual/Prayers searchers
- Recovery: Recurse Mitsurugi monsters from the GY via Mitsurugi no Mikoto Saji/Kusanagi and Ragged Records of Rites
- After siding: No side deck in the export, so no post-side plan can be evaluated
Why it scores here
The list reliably opens a Fiendsmith or Mitsurugi starter often enough: the archetype core group has about 0.84 probability of at least one copy in a 5-card opening hand, and 22 searcher-text cards give a high chance of finding a line. Its conversion ceiling is real (Ame no Murakumo, Ruler, Desirae) but no recorded boards exist, so the ceiling and median are both Inferred from text alone. Interaction is the strongest part: 7 hand traps and 6 negation-text cards let it contest an opponent's first board, and going-second hand-trap odds are about 0.66. The score is held down by structure rather than power: 16.7% exact-archetype purity means 50 of 60 cards split across Mitsurugi, Mulcharmy, Cyber and generic staples, and there is no side deck. Seven over-limit copies make the deck illegal, so the score is capped. Popularity and archetype usage did not earn any points, and no card scores were averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(>=1 Engraver/Mitsurugi starter in 5) about 0.30 per 3-copy card; archetype core P(>=1 in 5) 0.835; limit fixes lower it (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 22 searcher-text cards and 3 Ritual lines are coherent, but 50 off-archetype copies create conflicting summon routes and dead draws (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | Ceiling from text only: Mitsurugi Ritual into Ame no Murakumo, Ruler and Fiendsmith Desirae; no recorded boards (Inferred) |
| D4 | Combo Floor & Median Output | 45 | Median output unknown without recorded boards; many lines need 2+ Ritual or Fusion steps, so the floor is low (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Redundant hand-trap and searcher starters (Ash, Droll, Nibiru, Mulcharmy) give independent routes after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 62 | Recursion through Mitsurugi Saji/Kusanagi and Ragged Records; 22 searchers give a grind engine (Inferred) |
| D7 | End-Board & Interaction Quality | 68 | 7 hand traps, 6 negation-text cards and Mitsurugi Great Purification give layered interaction (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second hand-trap odds about 0.66; Mitsurugi Great Purification and Ruler add board-breaking (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | Ame no Murakumo 3200 ATK, Ruler 3000 ATK, Nibiru 3000 ATK and Fiendsmith's Lacrima 2400 ATK with an ATK debuff give strong end-board closing (Verified stats, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 45 main cards but 21 distinct, several split across sub-archetypes, and 3-copy restricted staples reduce coherence (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra slots: 7 Link, 6 Fusion, 2 Xyz; Limited Fiendsmith cards are over-limit and Xyz is thin (Verified composition) |
| D12 | Side Deck Adaptability | 10 | No side deck present (side_count 0), so post-side adaptability is effectively absent (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link and no dated meta sample; Meta Power is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Ritual, Fusion and Link sequences with many decision points on each turn (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_deck (-4); illegal_cap (0). Final formula: No reliable metagame: 0.80*Structural(54) + 0.20*TournamentReliability(45) = 52.2; context modifiers -12 gives 40.2; Illegal cap applied, final 30
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.84 · 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
- Dense searcher density (22 searcher-text cards) keeps starters reachable
- Layered interaction: 7 hand traps plus negation text
- Strong Extra Deck boss threats (Ame no Murakumo, Ruler, Desirae, Lacrima)
Weaknesses
- Illegal list: seven cards over copy limit
- Low archetype purity (16.7%) and split engines
- No side deck
- No recorded combos or tournament data
Critical choke points
- Fiendsmith Engraver and Fiendsmith's Tract are both over the limit, so the search chain is cut when the deck is legal
- Mitsurugi Ritual and Prayers rely on Reptile monsters that must be in hand or on field
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2 Pre-Preparation of Rites and 2 Mitsurugi Prayers | Non-restricted searchers or Ritual staples up to the limit | Fixes the copy-limit violations so the deck becomes legal, which lifts the Illegal cap |
| 2 | 1 Ash Blossom and 1 Super Polymerization | Side-deck slots (up to 15) | Adds post-side flexibility and reduces dependence on restricted interaction |
| 3 | Off-archetype Mulcharmy copies | Fiendsmith or Mitsurugi-specific starters | Raises archetype purity so the engine is coherent |
Evidence & confidence
- Verified: Main 45 and Extra 15 are within the TCG size rules; Seven copy-limit violations across restricted cards; No side deck present; Archetype core P(>=1 in 5) 0.8352; Exact-name archetype purity 16.7%
- Inferred: Starter consistency estimates; Interaction quality from negation and hand-trap text; Going-second hand-trap odds 0.66
- Provisional: Meta Power (no dated sample); Matchup fit (no tournament data)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is provisional without a dated metagame sample No side deck in the export
