Legality
Main 43 / Extra 12 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).
Identity & game plan
- Win condition: Fiendsmith Fusion/Link pressure (Fiendsmith's Rextremende, Fiendsmith's Lacrima) and Mitsurugi Ritual boards, if the copy violations are corrected; Chaos Angel and Galaxy-Eyes Photon Lord as Extra Deck pressure with partial Ritual support
- Turn 1 (going first): Search a Fiendsmith or Mitsurugi starter (Engraver, Tract, Mitsurugi Prayers or Mitsurugi no Mikoto) and build a Link or Fusion board, protected by Ash Blossom and Infinite Impermanence (Inferred)
- Turn 2 (going second): Hand traps (Ash Blossom, Droll & Lock Bird, Infinite Impermanence) to stop the opponent's board, then Ritual or Fusion follow-up from the hand (Inferred)
- Recovery: Recover Fiendsmith and Mitsurugi monsters from the GY through Lacrima, Lurrie, and Mitsurugi Mirror; no combo data to confirm the lines (Inferred)
- After siding: No side deck is run, so no post-side plan exists in this list
Why it scores here
This list is Illegal: five cards exceed their OCG copy limits (Engraver, Tract, Mitsurugi Prayers, Pre-Preparation of Rites at 3 copies with 1 legal, and Ash Blossom at 3 copies with 2 legal), so it is scored structurally only and capped at 30. Starter access is good on paper: the archetype-core group has a 0.82 chance of at least one core card in a 5-card opening hand, and the searcher text group reaches 0.99, so the deck can usually find a starter. Interaction is dense, with seven hand traps and about nine negation and removal effects, which supports its board-control shell. Consistency is weakened by a low archetype purity of 25.5% (14 exact Fiendsmith copies against 41 off-archetype) and 24 distinct main-deck cards split across Mitsurugi, Mulcharmy, Greed, and generic cards. Going-second and side-deck scores are low because there is no side deck and no recorded combo or tournament evidence. The score comes from consistency, interaction, and structure on the list as a whole, not from averaging card scores or from Fiendsmith's popularity (usage data shows the core Requiem, Sequence, and Desirae are missing).
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 58 | P(≥1 of Engraver/Tract in 5-card hand) ≈ 0.32 each at 3 copies, but only 1 legal copy each; archetype-core P ≈ 0.82 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | Nine hand-trap and tech cards plus Mulcharmy and Droll reduce brick risk, but Pre-Preparation and Ragged Records add redundancy (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No parseable boards; Fiendsmith Lacrima and Rextremende give a high ceiling from text alone (Inferred) |
| D4 | Combo Floor & Median Output | 50 | No combo median is available; typical output is unknown without recorded boards (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Ash, Infinite Impermanence, Droll and Lacrima give some redundant recovery routes after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Searchers and GY-recursion text (Lacrima, Lurrie, Mitsurugi Mirror) support rebuild, but Extra Deck costs are high (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | Seven hand traps, Ash Blossom, Infinite Impermanence and Galaxy-Eyes negation give layered interaction (Inferred semantic read) |
| D8 | Going-Second & Board-Breaking Power | 50 | Going-second plan relies on hand traps and Droll; no board-breaker count is verified (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Rextremende (3000 ATK) and Chaos Angel (3500 ATK) provide closing bodies (Verified stats) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 43 main cards with 41 off-archetype copies, 24 distinct, and five over-limit cards lower coherence (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 55 | Twelve Extra Deck cards across Link, Fusion, Synchro, and Xyz from several archetypes reduce coherence (Verified composition) |
| D12 | Side Deck Adaptability | 20 | No side deck is run (Side Deck size 0) (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated meta sample or tournament link exists; archetype share is not available (Provisional) |
| D14 | Pilotability & Error Tolerance | 50 | Multi-step Fusion, Ritual, and Link lines with several decision points (Inferred) |
How the score was computed
Strategy profile: Midrange 85 / Toolbox 15. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (illegal copy overrun) (-12). Final formula: No reliable metagame: 0.80*Structural(52) + 0.20*TournamentReliability(45) + Modifiers(-12) = 38.6, then Illegal cap applied: 30
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.82 · 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 hand-trap and negation package (7 hand traps, about 9 negation texts)
- High searcher density (24 searcher-text cards) gives a high starter-access probability
- Strong closing bodies in Rextremende and Chaos Angel
Weaknesses
- Illegal as submitted: five cards exceed copy limits
- Low archetype purity (25.5%) and 41 off-archetype copies
- No side deck (Side Deck size 0)
- No combo or tournament evidence to confirm conversion or median output
Critical choke points
- Engraver and Tract are the main starters, and each is legal at only 1 copy
- Core Fiendsmith Fusion and Link cards (Requiem, Sequence, Desirae) are missing, so the engine may not function as its archetype intends
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Two copies each of Pre-Preparation of Rites, Mitsurugi Prayers, Fiendsmith Engraver, and Fiendsmith's Tract, plus one Ash Blossom | Single copies or reduce the count to the legal limit; add missing core cards only if they are available in the format | The deck is Illegal as submitted; fixing copy limits is required before any normal score can apply |
| 2 | Off-archetype tech cards with low synergy (for example Night Sword Serpent, Fabled Lurrie) | Core Fiendsmith support (Requiem, Sequence, Desirae) if legal | Raises archetype purity and engine coherence (D10, D11) |
| 3 | None | A side deck of 0 to 15 cards | Adds post-side adaptability (D12) and matchup flexibility (D13) |
Evidence & confidence
- Verified: Main deck 43 cards, Extra 12, Side 0 (within OCG size rules); Five copy-limit violations and nine restricted cards in the list; Archetype purity 25.5% (14 of 55 cards exact Fiendsmith); Usage stats: Requiem, Sequence and Desirae are core but absent
- Inferred: Starter access 0.82 from hypergeometric archetype-core estimate; Hand-trap and negation density as a going-second plan; Consistency and interaction scores from card text
- Provisional: Meta Power (null, no dated metagame sample); Matchup fit (no tournament or meta data)
- Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link, so archetype meta-share and pilot results are absent No win-rate telemetry for OCG Fiendsmith No side deck, so post-side performance cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
