Witchcrafter Deck #772087 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±5 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra Deck boss summons (Magistus / Endymion / Fairy Tail link, xyz and fusion monsters) backed by a broad negation suite; no recorded combo boards to confirm a reliable conversion.; Fairy Tail and Mulcharmy draw and summon pressure through Fairy Tail Matchgiru, Mulcharmy Fuwalos and Purulia.
• Turn 1 (going first): Open a Witchcrafter/Magistus/Endymion starter (Verre, Genni, Regulus, Crowley or Verre Magic) and extend into a Link or Fusion boss while holding Ash Blossom and Droll for the opponent's first response.
• Turn 2 (going second): Use the hand traps (Ash Blossom, D.D. Crow, Ghost Ogre, Droll & Lock Bird) and Forbidden Droplet / Forbidden Crown to break the opponent's board, then rebuild through Extra Deck summons.
• Recovery: Fairy Tail Ball and Once Upon a Fairy Tail recover monsters from the Deck or banish, and Pot of Sloth replenishes the hand; the recovery route depends on the deck's Fairy Tail subset of 9 cards.
• After siding: Not assessable: the deck has 0 Side Deck cards, so there is no post-side plan.

Why it scores here

The deck is illegal as built: Ash Blossom & Joyous Spring runs 3 copies against an OCG Semi-Limited limit of 2, so the score is capped and reported as structural only. Its 55-card Main Deck spans at least four sub-archetypes (Magistus, Fairy Tail, Endymion, Forbidden and Mulcharmy) with only one exact Witchcrafter card, which weakens engine coherence and makes starter access depend on mixing several unrelated engines. Opening access is moderate: the archetype core group gives P(at least one core card in a 5-card opening hand) of about 0.76, but no single starter is above 0.26 and the hand-trap group is about 0.68 going second, both Inferred from hypergeometric estimates. Interaction is the strongest part of the list (18 negation-text cards and 9 hand traps), and the Extra Deck supplies several boss options, but there are no recorded combo boards, no side deck and no tournament data, so the floor, median and ceiling of conversion are unmeasured. The score did not come from averaging card scores or from the archetype's popularity; the 30 reflects the system's coherence, interaction and legality problems.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 42, Going First ≈ 38, Going Second ≈ 36, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy limit (-8); Engine conflicts (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 40.9, then modifiers -11 (illegal-deck cap applied, theoretical/structural only) = 30

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

• Dense negation and hand-trap suite (18 negation-text cards, 9 hand traps) covering both going-first and going-second turns.
• Eight of the 25 usage-core cards are present, so the list keeps the archetype's accessible backbone.
• All 15 Extra Deck slots are used, giving several boss routes through Magistus, Endymion and Fairy Tail.

Weaknesses

• Illegal as built because of the three Ash Blossom copies.
• Low exact-archetype purity (1.4%) across at least four sub-archetypes, reducing engine coherence.
• No Side Deck, so there is no best-of-three adaptation.
• No recorded combo boards, so conversion output is unmeasured.

Critical choke points

• Only 0.25 chance per copy-group of drawing a single Ash Blossom or Forbidden Droplet in 5 cards, so interaction depends on one or two hand traps.
• Engine starters are spread across sub-archetypes; a single missing starter can leave the Extra Deck boss without a route.

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main, 15 Extra, 0 Side; Ash Blossom & Joyous Spring over the Semi-Limited limit (3 run, 2 legal).; Limited cards run at 1 copy each: Droll & Lock Bird, Fairy Tail - Snow, Instant Fusion, Solemn Judgment, Summon Sorceress.; Usage core present 8 of 25 (32%).
• Inferred: Starter access P(at least one core card in a 5-card hand) about 0.76.; Hand-trap availability about 0.68 going second.; Interaction density is high from the negation and hand-trap text roles.
• Provisional: Meta Power and the format-fit dimension D13 with no dated metagame sample and no tournament link.
• 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, going-second, matchup and brick rates are Inferred or Unknown Meta Power is provisional without a dated metagame sample no side deck: post-side plan and D12 cannot be measured
