Shaddoll Deck #771343 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 58 / Extra 12 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion Summon Shaddoll boss monsters (El Shaddoll Shekhinaga, Meshahrail, Apkallone, Winda) and attack with them; Flip-effect Shaddoll monsters and Reeshaddoll Wendikurhu to disrupt the opposing board and grind
• Turn 1 (going first): Open a Shaddoll Fusion / Lev Shaddoll Fusion / Fusion Deployment starter, Fusion Summon a Shaddoll boss from the Extra Deck, and use Shaddoll Schism or Solemn Judgment to protect the board
• Turn 2 (going second): Use Ash Blossom and Droll & Lock Bird as hand traps to slow the opponent's first engine, then rebuild a Fusion line through Shaddoll Fusion and Void Unleashing
• Recovery: Recover from the GY with Shaddoll Fusion and Naelshaddoll Ariel effects, and use Void Unleashing to add Shaddoll cards back to hand
• After siding: No side deck is registered (Side Deck size 0), so no post-side plan can be evaluated

Why it scores here

The deck's core Shaddoll and fusion enablers are reasonably accessible: the archetype core group gives about a 76% chance of at least one core card in a 5-card opening hand (Inferred), and there are five different fusion starters. The Extra Deck has real boss options (Shekhinaga, Meshahrail, Apkallone, Winda) and the deck has layered interaction through flip-effect monsters, Ash Blossom, Solemn Judgment and Droll & Lock Bird. Score is held down by the copy-limit violation, which makes the list Illegal, and by three Fusion Deployment and Shaddoll Fusion copies that can brick when the required materials are missing. No combo boards, tournament results or side deck were supplied, so the score rests on the system's structure rather than popularity or card scores, and it is not an average of card scores. Because the list is Illegal, the Final score is capped and this evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Combo primary; Midrange secondary, disclosed as a profile choice rather than a blended weight set. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-4); unresolved_passcode (-2); no Side Deck (-1); illegal_cap (-16). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*55 + 0.20*45 = 53, then context modifiers (-7) give 46; the deck is Illegal (Ash Blossom over copy limit), so the Final score is capped at 30 and is theoretical/structural only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.76 · key two-card combo ≈ — · full-brick estimate ≈ 0.24 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is accessible (about 76% at least one in a 5-card hand, Inferred)
• Five distinct fusion starters and 12 Extra Deck fusions give flexible boss access
• Layered interaction: Solemn Judgment, Droll & Lock Bird, Harpie's Feather Duster, Lightning Storm and flip-effect removal

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring is run 3 times against a limit of 2
• No combo boards, tournament data, or side deck to measure real conversion or post-side plans
• Fusion Deployment and Shaddoll Fusion create brick risk without the right materials
• Only 35.7% exact-archetype purity; 45 off-archetype copies lower compactness

Critical choke points

• Fusion Summon requires a Shaddoll starter and matching materials; losing the starter removes the boss plan
• Shaddoll Fusion is needed for both recursion and summoning, so one disruption can stall both lines
• Ash Blossom copy count must be cut to 2 before the deck can be played

Recommended changes

Evidence & confidence

• Verified: Legality: 58 main, 12 extra, 0 side; Ash Blossom & Joyous Spring run 3 vs legal limit 2 (Semi-Limited); Six Limited cards each run at 1 copy, within their limit; Card text and stats for resolved cards, including Shekhinaga ATK 2600 and Meshahrail ATK 2800
• Observed: Exact archetype purity 35.7% and copy histogram (17 one-of, 4 two-of, 11 three-of)
• Inferred: At least one archetype core card in a 5-card opening hand ≈ 0.76; Brick proxy ≈ 0.24 for fusion-only hands; Going-second hand trap access ≈ 0.36
• Provisional: Meta position of Shaddoll in OCG (no dated metagame sample supplied)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent One passcode (20366274) could not be resolved to a card and was counted as main deck No side deck (Side Deck size 0): post-side performance cannot be assessed No win-rate telemetry exists in YGOVN; going-first/second, matchup and brick rates are inferred or unknown Meta Power is provisional unless a dated metagame sample is supplied
