Identity & game plan
- Win condition: Fusion-summon Shaddoll boss monsters (Meshahrail, Shekhinaga, Winda, Apkallone) and ritual boards (Black Chaos, Magician of Dark Chaos, Black Luster Soldier) that are protected by Shaddoll negation and flip removal.; Light and Darkness Ritual boards through Black Chaos, Magician of Dark Chaos and Black Luster Soldier, reached via Mind Shuffle, Griffoh, Skull Archfiend and Celtic Mystic.
- Turn 1 (going first): Open with a Shaddoll Fusion-spell starter or a flip monster (Squamata, Shaddoll Beast, Hedgehog, Nehshaddoll Genius) that draws or searches, then fusion into a Shaddoll boss while holding Solemn or Evenly Matched for the response.
- Turn 2 (going second): Use hand traps (Droll and Lock Bird, Evenly Matched) and Solemn to break the opponent's first board, then rebuild through fusion or the ritual package on a later turn.
- Recovery: Recursion from the GY: Skull Archfiend, Naelshaddoll Ariel banish-to-revive, Shaddoll Dragon, and Void Unleashing search. Fusion spells and Shaddoll Hedgehog re-fill the hand.
- After siding: No side deck is listed, so there is no evidenced post-side plan. Best-of-3 play is currently unsupported by the list.
Why it scores here
The deck reliably opens a fusion-based Shaddoll plan: nine fusion-spell starters (three each of Shaddoll Fusion, El Shaddoll Fusion and Lev Shaddoll Fusion) give roughly a 58% chance of at least one in an opening five-card hand (hand-computed hypergeometric, Inferred). Its strength is layered interaction and redundancy: flip removal, negation-on-summon fusion monsters, Solemn and Evenly Matched, and several recursion routes keep it running after disruption. Ceiling and median output could not be measured because no recorded boards exist, so those scores are text-based Inferred reads. The score is not earned by Shaddoll being a popular archetype, and it was not produced by averaging card scores. Structural score is 59 with no meta credit, Tournament Reliability is 52, and the -5 modifiers cover the dead Extra Deck slots, the Light and Darkness Ritual engine conflict and the lack of a side deck.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | P(>=1 of 9 fusion-spell starters in opening 5) ~0.58, hand-computed from copy counts; no combo boards to confirm the conversion (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 52 | 58 main cards with 16 singletons, 28 level-0 spell/trap cards, 3 hand traps and a Light and Darkness Ritual package that is off-plan in many hands (Inferred) |
| D3 | Combo Conversion & Ceiling | 62 | Text-only ceiling: Black Chaos, Magician of Dark Chaos and Shaddoll fusion chains give high-output lines, but no parseable recorded boards exist (Inferred) |
| D4 | Combo Floor & Median Output | 50 | No median or floor data (combos_evidence total 0); the ritual lines depend on specific GY and hand resources, so median is set at neutral (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 66 | Nine fusion starters, Squamata and Shaddoll Beast draws, Hedgehog search, Ariel revive and Skull Archfiend recursion give multiple independent routes (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 68 | 11 searcher-text cards, Pot of Sloth, Mulcharmy draw, Void Unleashing and Shaddoll Hedgehog refuel the hand, with no resource-signature data (Inferred) |
| D7 | End-Board & Interaction Quality | 74 | 18 removal-text cards, 3 negation-text cards, Solemn Judgment and Solemn Accusation, Squamata and Ariel flip removal, Shaddoll Dragon bounce, Evenly Matched and Droll (Verified text / Inferred strength) |
| D8 | Going-Second & Board-Breaking Power | 64 | Black Luster Soldier and Black Chaos at 3000 ATK, Meshahrail unaffected by Spell/Trap effects, and Droll for the second-turn follow-up (Inferred) |
| D9 | Offensive Pressure & Closing Power | 66 | Boss ATK values of 2800 to 3000 (Black Chaos, Black Luster Soldier, Magician of Dark Chaos, Meshahrail, Shekhinaga) with no board data (Verified stat / Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 58 of a 60 max in main with 16 singletons and several off-plan packages (Mulcharmy, Pot of Sloth, Santa Claws, LDR core) lowers compactness (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 38 | Native Extra slots are Meshahrail, Apkallone, Winda, Shekhinaga and Grysta; N'tss needs Synchro and Xyz monsters, and Infernoid Evil needs two Infernoid monsters, which this list lacks, so both are near-dead (Verified card text / Inferred) |
| D12 | Side Deck Adaptability | 15 | The side deck is empty (side_count 0), so there is no post-side plan at all (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame or tournament data; archetype meta-share is absent. Neutral placeholder, excluded from Structural (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step fusion and ritual sequences with several floating effects (Griffoh, Mind Shuffle, Black Chaos placement) are demanding, and combo step data is absent (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 64, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Dead Extra Deck slots (-2); Engine conflict (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*59 + 0.20*52 - 5 = 52.6 -> 53
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.58 · 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
- Nine fusion-spell starters give a redundant opening route
- Layered interaction: flip removal, negation fusion monsters, Solemn, Droll and Evenly Matched
- Multiple recursion and search routes (Hedgehog, Void Unleashing, Ariel, Skull Archfiend)
- High-ATK ritual and fusion bosses (2800 to 3000)
Weaknesses
- No side deck, so no post-side adaptation
- Two Extra Deck slots (N'tss, Infernoid Evil) are dead without enablers
- Two engines (Shaddoll Fusion and Light and Darkness Ritual) compete for hand space
- Low exact-name purity (39.4%) signals an unfocused list
Critical choke points
- Fusion-spell starter availability (about 58% in an opening five)
- Black Chaos and the ritual package depend on specific GY resources
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | N'tss and Infernoid Evil (Extra Deck) | Extra Deck options whose enablers are in the list, or a Shaddoll-compatible fusion | Both are dead in this build; freeing those slots raises Extra Deck efficiency (D11) |
| 2 | Off-plan ritual or greed cards with the weakest Shaddoll synergy | A side deck of 5 to 15 cards | The side deck is empty, which limits best-of-3 adaptability (D12) |
Evidence & confidence
- Verified: Main 58 and Extra 13 are within size rules; Five Limited cards each run at 1 copy, which is legal; Card text for all resolved cards; Usage stats: Shaddoll Dragon, Naelshaddoll Ariel and other core rows
- Inferred: Fusion-spell opening probability of about 0.58; Interaction strength from card text; Dead Extra Deck slots from card-text enablers; Engine conflict between the fusion and ritual packages
- Provisional: Meta power and matchup fit (no dated sample)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record are absent Usage stats list El Shaddoll Apkallone and El Shaddoll Shekhinaga as missing core, but the card list contains Apkallone x2 and Shekhinaga x1. The card list was trusted; the usage row is inconsistent 1 passcode (20366274, 2 copies) is unresolved and counted as main, which is why the status is Legal with warning No side deck (side_count 0) No win-rate telemetry exists in YGOVN
