Dark World Deck #755010 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters: Topologic Blaster Dragon (3500 ATK), Grapha, Dragon Overlord of Dark World (3200 ATK), Underworld Goddess of the Closed World (3000 ATK), Number 1: Infection Buzzking (3000 ATK). Theoretical only while the deck is illegal.; Board wipes and removal from Reign-Beaux, Overlord of Dark World, Clorless, Chaos King of Dark World and Eradicator Epidemic Virus (text-based, Inferred).
• Turn 1 (going first): Opening-hand searcher or hand-revealing Danger! monster (about 0.83 chance of a searcher in 5 cards) into Snoww, Genta or The Gates of Dark World, then a Fiend Extra Deck summon. Theoretical, Inferred.
• Turn 2 (going second): Hold Chaos Hunter, Skill Drain and Eradicator Epidemic Virus to answer the opponent's first board, then rebuild through Reign-Beaux or Grapha from the Graveyard. Theoretical, Inferred.
• Recovery: Recursion from the Graveyard: Reign-Beaux and Grapha special summon by returning Dark World monsters, Dark World Accession re-adds from the GY, and Dark Corridor and Dark World Dealings refill the hand.
• After siding: None. The Side Deck is empty (side_count 0), so there is no post-side plan.

Why it scores here

The list is Illegal in OCG: three Forbidden cards (Number 60, Saryuja Skull Dread, Number 41) are each run at 1 copy, so the normal Final score is capped at 20 and the Structural figure of 59 is theoretical only. As a system, the Dark World shell opens reliably (about 0.83 chance of at least one searcher in a 5-card opening hand, and 0.92 for at least one archetype-core card), and the Extra Deck supplies large boss bodies plus real interaction through Skill Drain, Eradicator Epidemic Virus, Reign-Beaux Overlord and Clorless. Floor and median output cannot be measured because no recorded boards exist, so those scores are text-only inference. Archetype popularity earned no points, card scores were not averaged, and the empty Side Deck and missing meta data hold the deck back.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 63, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-8); No Side Deck (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + modifiers = 0.80*59 + 0.20*50 - 11 = about 46, then capped at 20 because the deck is Illegal (Forbidden cards). Structural 59 is theoretical only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · 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

• Redundant searchers and starters: Snoww, Genta, Dark Corridor, Reign-Beaux and The Gates of Dark World, all at 2 or 3 copies
• Layered interaction: Skill Drain, Eradicator Epidemic Virus, Reign-Beaux Overlord and Clorless
• High-ATK Extra Deck bodies (Topologic 3500, Grapha Dragon Overlord 3200, Underworld Goddess 3000)
• Graveyard recursion (Reign-Beaux, Grapha, Chaos Hunter, Dark World Accession) gives continuation after disruption

Weaknesses

• Illegal list: three Forbidden Extra Deck cards
• Empty Side Deck, so no post-side adaptation
• Low exact-name purity (40%); generic and Danger! copies dilute the engine
• Score is theoretical only: no recorded boards, no tournament data, no win-rate telemetry

Critical choke points

• Dark World starter hand: the searcher group is about 0.83 in 5 cards, so one missing starter leaves the line dead
• Skill Drain's 1000 LP cost and its Limited status (1 copy run) constrain when interaction can be used
• Forbidden Extra Deck cards: the deck cannot be played as listed until they are replaced

Recommended changes

Evidence & confidence

• Verified: Illegal status: three Forbidden cards run at 1 copy each; Main 55 (40-60), Extra 15 (0-15), Side 0 (0-15); the copy histogram sums to 55; Banlist statuses: Card Destruction and Skill Drain are Limited at 1 copy, within limit; Hypergeometric draw probabilities from the resolved Main Deck list; Archetype usage inclusion percentages
• Inferred: Engine accessibility and brick risk from the draw probabilities and card text; Interaction quality read from card text (Skill Drain, Eradicator, Reign-Beaux Overlord, Clorless); Ceiling and going-second strength from text, not from boards; Dimension scores D1 to D11 and D14
• Provisional: Meta Power (null) and matchup fit D13, since no dated metagame sample exists; Side-deck adaptability D12 cannot be measured without post-side data
• 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 No win-rate telemetry (going-first/second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Usage statistics in_this_deck flags appear to check the Main Deck only: Muckraker From the Underworld, Underworld Goddess of the Closed World and Grapha, Dragon Overlord are present in the Extra Deck list but flagged false; the card list was trusted Side Deck is empty, so no post-side evidence exists
