Identity & game plan
- Win condition: Fusion Summon Shaddoll Fusion monsters (Construct, Meshahrail, Shekhinaga, Winda, Apkallone) and attack or use their board-control effects; Interaction-backed board control (Squamata, Dragon, Grysta, Ariel, Mind Mirror Force, Evenly Matched) that trades for the opponent's board and keeps the Fusion line alive
- Turn 1 (going first): Open on a Shaddoll starter (Squamata, Hedgehog, Falco, or Fusion spell) that searches or summons a second Shaddoll piece, then Fusion Summon through Lev Shaddoll Fusion, Shaddoll Fusion, or El Shaddoll Fusion
- Turn 2 (going second): Hold hand traps (Ash Blossom, Effect Veiler, Ghost Ogre, Maxx C, Nibiru) to stop the opponent's first summons, then rebuild the Fusion line from the GY and banished Shaddolls
- Recovery: Recover through GY-to-board Shaddoll recursion (Shaddoll Core, Falco, Reeshaddoll Wendi, Naelshaddoll Ariel) and the search-from-GY effects on the Fusion monsters
- After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists in the evidence
Why it scores here
This deck is scored as a theoretical, structural-only read because it is Illegal: Baronne de Fleur is Forbidden in OCG and is run once, so the list is capped at 40 and does not receive a normal Final Contextual score. Within that cap, the structure is coherent around a Shaddoll Fusion engine: the archetype core is in roughly 69% of opening 5-card hands by hypergeometric estimate (Inferred), and the Shaddoll starters (Squamata, Hedgehog, Falco, Core) give multiple independent openings. Interaction is dense, with 15 hand traps, 14 negation-text cards and 24 removal-text cards, which earns the end-board score (D7). The deck was not scored on its popularity or meta-share, and card scores were not averaged into the deck score. Conversion and median output are text-only inferences because no recorded boards exist, and the 55-card main deck with 21 level-0 spells and traps dilutes starter density, which holds efficiency down.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(at least one archetype-core card in opening 5) ≈ 0.69 across 11 core copies; Fusion starter density is good but not verified (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | About 31% of 5-card openings have no core card and Lev Shaddoll Fusion x3 and Squamata x3 add redundancy; 21 level-0 spells and traps raise brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 65 | Fusion chains via Construct, Meshahrail and Shekhinaga produce high-ceiling boards; no recorded combos exist, so this is a semantic read from card text (Inferred) |
| D4 | Combo Floor & Median Output | 52 | No combos or board data supplied, so the floor and median are unknown and are kept near the middle (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 65 | Multiple recursion routes (Core, Falco, Wendi, Ariel, Hedgehog) and 15 hand traps give alternative lines after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 62 | Searchers and GY-to-board recursion on Shaddoll monsters and Fusion spells regenerate resources (Inferred from text) |
| D7 | End-Board & Interaction Quality | 72 | Layered interaction: Squamata, Dragon, Grysta, Ariel, Mind Mirror Force, Evenly Matched plus hand traps; 14 negation-text cards (Inferred semantic read of card text) |
| D8 | Going-Second & Board-Breaking Power | 66 | Going-second hand traps (Ash x2, Ghost Ogre, Veiler, Maxx C) and negate-capable Fusion monsters challenge an established board; Maxx C is Limited but run at its legal 1 copy (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Extra Deck monsters at 2500 to 2800 ATK (Construct, Meshahrail, Shekhinaga, Apkallone) give closing pressure (Verified stat; closing use Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 55-card main with only 28 distinct cards and 21 level-0 spells and traps; the extra copies dilute starter density (Verified counts, Inferred consequence) |
| D11 | Extra Deck Efficiency & Coverage | 60 | Full 15-card Extra Deck with 12 distinct cards; the banned Baronne de Fleur uses a slot that must be replaced (Verified) |
| D12 | Side Deck Adaptability | 25 | No Side Deck (0 cards), so there is no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or meta-share is available, so format fit is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step Fusion lines with several Flip effects and a 15-card Extra Deck require many decisions per turn (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (Forbidden card in Extra Deck) (-12); No side deck (0). Final formula: No reliable metagame: 0.80*Structural(59.2) + 0.20*TournamentReliability(48) = 56.96; Illegal deck capped to 40 under the legality rule (theoretical/structural-only)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Layered interaction: 15 hand traps plus 24 removal-text cards
- Fusion-based engine with several 2500-2800 ATK Extra Deck closers
- Multiple recursion routes from the GY and banish zone
- Archetype core is present in about 69% of opening 5-card hands
Weaknesses
- Illegal: Baronne de Fleur is Forbidden and over the copy limit
- No Side Deck, so no post-side adaptability
- 55-card main with 21 level-0 spells and traps dilutes starter density
- No recorded combos, so ceiling and median are text-only
Critical choke points
- Fusion Summon enablers (Lev Shaddoll Fusion, Shaddoll Fusion, El Shaddoll Fusion, Nephe Shaddoll Fusion) all depend on the Shaddoll core
- Single Forbidden Extra Deck slot (Baronne de Fleur) must be replaced before the list is legal
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Baronne de Fleur (Forbidden, 1 copy) | A legal Extra Deck Shaddoll Fusion or Synchro of the same role | Restores legality (Verified); without it the deck cannot receive a normal score |
| 2 | One level-0 Spell or Trap (non-core) | Shaddoll Beast (usage stat 56.25%, not in this deck) | Usage stat shows Shaddoll Beast as an archetype-standard card (Verified usage); reduces dilution (Inferred) |
| 3 | A tech card with lower role density | Foolish Burial (usage stat 62.5%, not in this deck) | Usage stat marks Foolish Burial as a core card in the archetype (Verified usage); adds starter access (Inferred) |
Evidence & confidence
- Verified: Baronne de Fleur is Forbidden and over the copy limit, so the deck is Illegal; Maxx C (Limited, 1 copy) and Ash Blossom (Semi-Limited, 2 copies) are within limits; Main 55 / Extra 15 / Side 0 match the size rules; Usage statistics for Shaddoll core cards
- Inferred: Archetype core opening probability ≈ 0.69 (hypergeometric); Interaction density and resilience from text role hints; Fusion engine ceiling from card text; Brick and dilution estimates
- Provisional: Meta power and format fit (no dated metagame sample)
- Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry (going-first/second, matchup, brick/starter/OTK rates) No Side Deck: post-side plan cannot be evaluated Meta Power is provisional without a dated metagame sample
