Shaddoll Deck #764251 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion Summon Shaddoll boss monsters from the Extra Deck (El Shaddoll Shekhinaga, Construct, Meshahrail, Winda, Anoyatyllis) and convert the board with ATK and negation or removal support; Link and Synchro pressure (Shaddoll Construct, Draco Berserker, Swordsoul Chengying, Super Starslayer TY-PHON) after the Fusion engine is online
• Turn 1 (going first): Open a Shaddoll flip monster or Lev Shaddoll Fusion and Shaddoll Fusion or El Shaddoll Fusion, then use the flip effects of Reeshaddoll Wendi and Naelshaddoll Ariel to recycle the GY into a Fusion Summon, with Heavy Storm or Harpie's Feather Duster for backrow
• Turn 2 (going second): Use the hand traps (Ghost Ogre and Snow Rabbit, Nibiru, Evenly Matched, Artifact Lancea) to disrupt the opponent's summon or board, then follow with a Fusion Summon through Shaddoll Schism or Lev Shaddoll Fusion
• Recovery: Recover through Shaddoll Hedgehog, Void Unleashing and Reeshaddoll Wendikurhu searches, and Resh Shaddoll Incarnation or Shaddoll Core GY recursion to rebuild a Fusion monster
• After siding: Not assessable: the list has no Side Deck, so no post-side plan exists in the evidence

Why it scores here

This list is Illegal in OCG: it runs Baronne de Fleur (Forbidden) and has 16 Extra Deck cards against a maximum of 15, so the score is a theoretical, structural-only read capped low and not a normal Final Contextual score. The engine is reasonably accessible: the 12 core Shaddoll copies give an estimated 0.73 chance of at least one in an opening 5-card hand (Inferred), and the 12 hand traps give about 0.80 chance of one in a going-second 6-card hand (Inferred). The deck has interaction breadth from Squamata, Shaddoll Dragon, Helshaddoll Hollow, Raigeki, Heavy Storm, Feather Duster, and the Fusion negations, which carries the Structural score. Floor and median output are not measurable because no combos were supplied, so those dimensions are text-based inference and held near neutral. Popularity did not earn points: the archetype core presence is used only as an accessibility signal, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo secondary not blended, as the weights are used as-is. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-12). Final formula: Illegal theoretical cap: 0.80*Structural(59) + 0.20*TournamentReliability(55) = 58.2, minus 12 banlist/legality modifiers = 46, capped at 35 for an Illegal list; structural-only, not a normal Final Contextual score

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.73 · 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

• Fusion engine with 12 core Shaddoll copies gives about 0.73 chance of a core starter in hand 5 (Inferred)
• Layered interaction: 12 hand traps and 24 removal-text cards (Verified text tags)
• Strong going-second hand-trap density, about 0.80 in hand 6 (Inferred)

Weaknesses

• Illegal list: Forbidden Baronne de Fleur and 16 Extra Deck cards against a limit of 15 (Verified)
• No Side Deck (Verified)
• Only 50% exact-name archetype purity, with 35 off-archetype copies (Verified)
• No combo or tournament evidence, so the ceiling and floor are unverified (Verified gap)

Critical choke points

• Fusion Summon requires a Shaddoll monster and a specific-attribute monster in the hand or field, so a missing Shaddoll monster or attribute monster shuts the engine down (Inferred)
• The Forbidden Baronne de Fleur slot and the 16th Extra Deck card must be removed before the list can be played (Verified)

Recommended changes

Evidence & confidence

• Verified: Legality: Baronne de Fleur is Forbidden in OCG and is present; Legality: Extra Deck is 16 cards against an OCG limit of 15; Composition: 54 Main, 16 Extra, 0 Side; exact-name purity 50%; Usage: Shaddoll Dragon, Naelshaddoll Ariel, and Shaddoll Schism are core cards present in the list
• Inferred: P(at least one core Shaddoll card in hand 5) = 0.731; P(at least one hand trap in hand 6) = 0.797; Interaction breadth from card text (negation, destruction, and return effects); Pilot complexity from Fusion-chain step count in card text
• Provisional: Meta Power is null: no dated metagame sample exists; Matchup fit and tournament reliability are provisional
• Data gaps: no combos supplied, so combo floor, median, and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry for going-first, going-second, matchups, or brick rates Meta Power provisional without a dated metagame sample no Side Deck in the list, so post-side evaluation is not possible
