Legality
Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Fiendsmith Fusion/Link boards built from Engraver and Tract searches, closed by Fiendsmith's Desirae-style boss monsters and off-archetype fusion/XYZ bosses (ABC-Dragon Buster, XYZ-Hyper Dragon Cannon); Machina/A-to-Z/ABC union boards with hand-trap protection and removal-based board control
- Turn 1 (going first): Open Fiendsmith starter (Engraver, Tract, Lacrima, or Fabled Lurrie discard-summon) and search a Fiendsmith or Union piece; hold hand traps for the opponent's first interaction
- Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Skull Meister, Droll and Lock Bird, Evenly Matched) to blank the opponent's starter, then rebuild through Mulcharmy draws and searchers
- Recovery: Mulcharmy draw engine and Union Hangar / Terraforming searches to refill hand after hand traps are spent
- After siding: Not evaluable: the deck runs 0 side cards, so there is no post-side plan
Why it scores here
This deck is scored as a connected system, not as an average of its card scores, and its legality is the first problem: it runs 3 Ash Blossom (2 legal), 2 Fiendsmith Engraver (1 legal) and 2 Fiendsmith's Tract (1 legal) under OCG limits, so it is capped as a theoretical, structural-only read. Its Fiendsmith engine is thin in this list: only 9 of 75 cards are exact-name Fiendsmith, the core Fiendsmith Requiem, Sequence and Desirae are absent, and the Extra Deck is filled with off-archetype fusion and XYZ bosses that the Engraver and Tract do not directly feed. Its real strength is interaction and resilience: 13 hand traps, 12 negation-text cards and 25 removal-text cards give it a credible going-second plan and several independent ways to blank an opposing starter. Popularity of the archetype did not earn points, since the archetype core is only 54.5 percent present and there is no tournament or meta data. The main deck is full at 60 cards with no side deck, which removes any post-side plan and keeps the reliability score low.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 42 | Fiendsmith starters present (Engraver x2, Tract x2, Lacrima, Lurrie) but core Extra pieces missing; archetype core group P(>=1 in opening 5) ~0.65 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 35 | 66 of 75 copies are off-archetype and 13 hand traps compete for the same hand slots; brick risk is high (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | No parsed boards; the ceiling comes from text only, via Tract/Engraver into off-archetype fusion and XYZ bosses (Inferred) |
| D4 | Combo Floor & Median Output | 35 | No combo data, so the median is unknown; the floor is weak because the engine depends on a specific starter and missing Extra pieces (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Multiple hand traps and a Mulcharmy draw engine give several independent answers to one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Searcher text count 17 and Mulcharmy draw effects support grind, but Union Hangar and Tract spend resources quickly (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Removal text 25, negation text 12, and Solemn Judgment plus Dominus Purge give layered end-board interaction (Verified flags, Inferred quality) |
| D8 | Going-Second & Board-Breaking Power | 55 | Hand traps and Skull Meister suit going second; board breaking relies on Ghost Ogre and Ash, which are limited to 1 copy each under legal limits (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Boss ATK 2800-3000 (ABC-Dragon Buster, XYZ-Hyper Dragon Cannon, Regulus) gives good closing power when reached (Verified stat, Inferred conversion) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 60-card main at maximum size with 33 distinct cards, 3-of spread across 11 cards, and 66 off-archetype copies lowering coherence (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 40 | 15-card Extra Deck with 13 distinct cards and no core Fiendsmith Link or Fusion pieces, so slots are used flexibly but inefficiently (Verified composition, Inferred use) |
| D12 | Side Deck Adaptability | 15 | 0 side cards, so there is no side plan at all (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament or meta data; archetype share is unknown (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Union, Link and Fiendsmith chains with many decision points between hand traps and searches (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 46, Going First ≈ 40, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); no Side Deck (-2). Final formula: Illegal cap: theoretical structural read. Structural 46 blended 0.80/0.20 with Tournament Reliability 35 gives 44, then modifiers -10 gives 34, capped to 30 under the illegal-deck rule. Meta Power is null (provisional).
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.65 · 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
- 13 hand traps and 12 negation-text cards give strong going-second interaction
- Searcher density (17) and Mulcharmy draw effects support card flow
- Boss monsters at 2800-3000 ATK give real closing power once a board is established
Weaknesses
- Illegal list: three copies over the in-format limit
- Only 9 exact-name Fiendsmith cards; core Fiendsmith Requiem, Sequence and Desirae are absent
- No side deck, so no post-side adaptation
Critical choke points
- Fiendsmith Engraver and Fiendsmith's Tract are the only engine-starting searches; limit 1 each makes the engine fragile
- Single-copy Lacrima and Fabled Lurrie are the only other Fiendsmith starters
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1 Ash Blossom & Joyous Spring, 1 Fiendsmith Engraver, 1 Fiendsmith's Tract | Legal copy count (1 Engraver, 1 Tract, 2 Ash) and replace the freed slots with off-archetype staples or the missing core Fiendsmith cards if legal | Restores legality so the deck can receive a normal score |
| 2 | Off-archetype fusion and XYZ extras (about 4 slots) | Fiendsmith's Requiem and Fiendsmith's Sequence (Unlimited) to complete the engine | Those two cards are in 80 percent or more of recorded Fiendsmith lists and are the engine's Link and Fusion enablers |
| 3 | Empty side slots | A 15-card side deck of hand traps and extra removal for the best-of-3 format | Adds a post-side plan, which the deck currently lacks |
Evidence & confidence
- Verified: Illegal status: 3 copy-limit violations under OCG BanList; 60 Main / 15 Extra / 0 Side sizes within size rules; Archetype purity 12 percent, 66 off-archetype copies; Core Fiendsmith cards Requiem, Sequence and Desirae absent
- Inferred: Engine consistency P ~0.65 from archetype core hypergeometric; Brick risk from off-archetype copies and hand-trap clog; Interaction and resilience from hand-trap and removal text flags
- Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data)
- Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta share and pilot record absent 1 passcode in CardIDList (10443957) could not be resolved and was counted as main no win-rate telemetry (going-first/second, matchup, brick and starter rates) exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied
