Shaddoll Deck #772770 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: ocg

Legality

Main 58 / Extra 13 / Side 0 — status: Legal with warning.

Identity & game plan

• Win condition: Fusion Summon Shaddoll boss monsters (El Shaddoll Meshahrail, Shekhinaga, Grysta, Winda, Apkallone) from the Extra Deck via Shaddoll Fusion, El Shaddoll Fusion and Lev Shaddoll Fusion, then attack or use the boss's negate and destroy effects.; Light and Darkness Ritual sub-engine (Magician of Dark Chaos, Black Luster Soldier, Black Chaos) as a second board presence when the fusion line is stopped.
• Turn 1 (going first): Open with a Shaddoll Fusion-type spell plus a Shaddoll monster, Fusion Summon a boss, and use Squamata or Hedgehog flip effects to clear or search. Hand 5 gives about 58% for at least one of the nine fusion spells.
• Turn 2 (going second): Use the 6-card hand's fusion spell and Solemn or Evenly Matched style interaction to answer the opponent's first board, then fuse through the remaining field. The deck has no side-deck plan, so it relies on the main-deck hand traps.
• Recovery: Recover from the GY through Shaddoll Squamata, Shaddoll Hedgehog, Reeshaddoll Wendi and Naelshaddoll Ariel, plus Void Unleashing and Ragged Records of Rites for search and recursion.
• After siding: Not available: the deck runs no Side Deck (side_count 0), so there is no post-side plan. This is a hard gap for best-of-3 play.

Why it scores here

The deck scores on the system, not on the average of its cards. Its nine fusion spells give a roughly 58% chance of at least one in a 5-card opening hand, so the core engine goes live often enough to be the main consistency driver. Its interaction (Solemn Judgment, Solemn Accusation, Evenly Matched, Squamata, Shaddoll Dragon, and negate effects on several bosses) is broad and layered, and the boss monsters have strong ATK, which is why the closing and end-board dimensions score well. The score is held down by a split engine: three Black Chaos and the Light and Darkness Ritual package need ritual material and a ritual spell that the list only runs in single copies, and the deck has 58 main-deck cards with only about 39% exact-name Shaddoll purity. The deck has no Side Deck, so best-of-3 adaptation is essentially absent. Popularity was not used to earn points, and no combo boards were available, so the combo dimensions are inferred from card text only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 60, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: engine conflict (-3); no side deck (-2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null)

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

• Hypergeometric odds of a live fusion spell are reasonable for a 58-card main deck.
• Layered interaction: Solemn trio, Evenly Matched, Squamata, Dragon, and boss negates.
• High-ATK fusion bosses give end-board and closing power.
• Recursion through several flip monsters supports interruption recovery.

Weaknesses

• No Side Deck, so no post-side adaptation.
• Split engine: Light and Darkness Ritual package conflicts with the fusion engine.
• Low exact-name archetype purity (about 39%) and 58 main cards reduce compactness.
• No combo or tournament data, so the power read is inferred from text.

Critical choke points

• Each fusion line needs a Shaddoll monster in hand or field plus a fusion spell; losing both to hand traps or Droll leaves the deck without a board.
• Three Black Chaos need ritual material and the Light and Darkness Ritual spell, which are single-copy.

Recommended changes

Evidence & confidence

• Verified: Main 58, Extra 13, Side 0 (OCG size rules 40-60 / 0-15).; Five Limited cards each run at 1 copy, within legal limit.; Exact-name Shaddoll purity 39.4% (28 of 71 copies).; Extra Deck is 12 Fusion + 1 Link.
• Inferred: At least one fusion spell in 5 cards about 0.58; 6 cards about 0.65.; Hand-trap and negate coverage supports going-second interaction.; Ritual sub-engine conflicts with fusion engine.
• Provisional: Meta Power is null (no dated metagame sample).; Tournament Reliability and matchup fit rest on archetype data only.
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot record are absent. One passcode (20366274) in the deck could not be resolved to a card and was counted as main. No win-rate telemetry (going-first/second, matchup, brick rate) exists; those signals are Inferred or Unknown. Meta Power is Provisional unless a dated metagame sample is supplied.
