Legality
Main 53 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).
Identity & game plan
- Win condition: Fiendsmith and Ryzeal Extra Deck bosses (Ryzeal Detonator, Ryzeal Duo Drive, Fiendsmith's Desirae) once a Xyz or Fusion board is established; Recursive Ryzeal Xyz pressure from the GY via Ryzeal Plugin and Ryzeal Duo Drive
- Turn 1 (going first): Open Fiendsmith Engraver or Fiendsmith's Tract to search or fuse toward a Link/Fusion board; hold Ash Blossom and Infinite Impermanence for the opponent's first activation
- Turn 2 (going second): Hand-trap the opponent's first summon or search (Ash, Droll & Lock Bird, Effect Veiler, Nibiru) and rebuild a Fiendsmith or Ryzeal board from the GY
- Recovery: Recover Fiendsmith and Ryzeal pieces from the GY through Lacrima, Ryzeal Plugin and Duo Drive attachments
- After siding: Not evaluable: the deck runs no Side Deck, so there is no post-side plan
Why it scores here
The score is built from the deck as a system and not from averaged card scores. Engine access is moderate: the deck runs 5 of the 11 archetype core cards, with 2 Fiendsmith starters (Engraver, Tract) and a P(at least one Engraver in a 5-card opening hand) of about 0.26 (Inferred). Interaction is dense, with more than 15 hand traps, negation and removal pieces, which carries D7 and D8. Median output is not measured because no boards were supplied, so D3 and D4 rest on text reads alone. The deck has no Side Deck, which caps D12 and the post-side plan. Popularity and archetype usage did not add points, and the Illegal copy-limit violations cap the final score regardless of the structural read.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 52 | P(at least one Engraver in 5-card hand) ≈ 0.26; 5 of 11 core cards present; 2-card bootstrap (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Copy histogram is spread across 31 distinct main-deck cards; many Ryzeal and Toy pieces need board state to function (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No parseable recorded boards; ceiling inferred from Ryzeal Detonator and Ryzeal Duo Drive text (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded combos, so no median or power distribution; score is provisional (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 58 | Multiple hand traps and a GY-based recursion line allow continuation after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Ryzeal Plugin, Duo Drive, and Fiendsmith GY recursion give partial recovery; no resource telemetry (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | Several negations, removal and board-wipe options including Harpie's Feather Duster and Lightning Storm; dense layering (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 62 | Going-second hand-trap coverage ≈ 0.92 in a 6-card hand; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 62 | Ryzeal Detonator 3000 ATK and Desirae 2800 ATK provide closing bosses; no direct-damage evidence (Verified stat, Inferred read) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 53 main cards with 25 level-0 non-monsters and 21 tech-tagged cards dilute engine density (Verified composition, Inferred read) |
| D11 | Extra Deck Efficiency & Coverage | 62 | Extra Deck of 14 with 9 Xyz, 3 Link and 2 Fusion covers multiple boss routes (Verified composition) |
| D12 | Side Deck Adaptability | 15 | No Side Deck; no post-side adaptation is possible (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link or dated meta sample; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Ryzeal and Fiendsmith sequencing with many decision points; high error-tolerance demand (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (copy-limit overages) (-10); no side deck (-2); illegal-deck cap (-8). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 50, plus modifiers -12 = 38; capped at 30 because the deck is Illegal (copy-limit violations). Theoretical/structural-only.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.26 · 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 interaction package: hand traps, negations and board removal across more than 15 cards
- Extra Deck has multiple boss routes (Xyz, Link, Fusion) with 14 cards
- Strong going-second hand-trap coverage
Weaknesses
- Illegal as built: six cards exceed their Limited or Semi-Limited copy limits
- Low archetype purity (16.4%): Ryzeal, Toy, Artifact and Seventh pieces dilute the Fiendsmith engine
- No Side Deck; no post-side plan
- Engine starter count is low (Engraver 3, Tract 2, Lacrima 1, Lurrie 1)
Critical choke points
- Fiendsmith Engraver is the main engine starter and is capped at 1 copy but run 3 times
- Ryzeal Xyz boss access depends on Ryzeal Plugin and GY Ryzeal monsters
- No recorded combos to confirm line reliability
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 2 copies of Fiendsmith Engraver (3 run, 1 legal) | Ryzeal or Fiendsmith staples that are unlimited or fit the copy limit | Resolves the most severe copy-limit violation and removes an illegal starter count |
| 2 | 1 copy of Ash Blossom & Joyous Spring | A non-overlapping hand trap or Toy starter | Brings Ash to its legal limit of 2 and keeps hand-trap density |
| 3 | 1 copy each of Seventh Tachyon, Ice Ryzeal, Sword Ryzeal and Fiendsmith's Tract | Unlimited-status alternatives in the same role | Clears the remaining Limited-status overages |
| 4 | Off-archetype tech cards with low synergy (Harpie's Feather Duster, Triple Tactics Thrust) | A Side Deck of 15 with graveyard and hand-trap answers | Restores post-side adaptation (D12), which is currently zero |
Evidence & confidence
- Verified: Copy-limit violations for 6 cards (legality block); Main 53 and Extra 14 within size rules; Archetype core present 6 of 11 (usage stats); Composition counts and Extra Deck breakdown
- Inferred: Engine starter probabilities (hypergeometric); Hand-trap density and interaction quality from card text; Brick risk and pilotability from card text
- Provisional: Meta Power (null); Matchup and format fit (no dated meta sample)
- Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot records absent No win-rate telemetry; going-first/second and matchup rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck has no Side Deck, so post-side evaluation is not possible
