Dark World Deck #768490 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 57 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Dark World Fiend-based recursion engine (Reign-Beaux, Grapha, Snoww, Sillva) converting recovered monsters into board-breaking Link and Fusion pressure; Danger! monster searches and Link beatdown (Topologic Blaster Dragon and Worldsea Dragon Zealantis are absent; Firewall Dragon Singularity and Underworld Goddess are not in the list either, so pressure relies on the Link monsters that are present)
• Turn 1 (going first): Open with a Dark World searcher or Danger! hand-discard (Chupacabra, Jackalope, Mothman, Nessie, Tsuchinoko) to Special Summon a second monster, then search a Dark World or Reign-Beaux via Snoww, Dark Corridor, or Dark World Accession
• Turn 2 (going second): Hand-trap-supported plan: Artifact Lancea and Harpie's Feather Duster or Heavy Storm answer the opponent's backrow, while Danger! discards start an engine for a Link Summon on the following turn
• Recovery: Dark World Grimoire and Grapha special summon from the GY by returning a Dark World monster, and Ceruli and Sillva re-enter from the GY on discard
• After siding: Not evaluable: the deck has 0 side cards, so no post-side plan exists

Why it scores here

The deck is scored as a system, not as an average of its card scores. Its Dark World core is present in the main deck (Reign-Beaux x3, Snoww x3, Ceruli x3, Grapha x2) and the archetype core group has about a 0.91 chance of at least one copy in a 5-card opening hand, so the engine is reachable on paper. Consistency is held back by the 3-copy starters, which each have only about a 0.24 chance of appearing in a 5-card hand, and by the lack of recorded boards, which leaves all combo ceiling and floor reads as text-only inference. Interaction is thin: three hand traps, Harpie's Feather Duster, Heavy Storm, and Card Destruction, with no floodgates and no negation text. The deck has no side cards, so it has no post-side plan, and it is also illegal: four Forbidden OCG cards are present (Triple Tactics Talent, Knightmare Goblin, Knightmare Gryphon, Number 60). Under the rubric this caps the score as a theoretical, structural-only read; popularity and usage statistics were not credited, and no metagame or win-rate data supports a meta claim.

Dimension scores

How the score was computed

Strategy profile: Balanced (default, strategy unclear from evidence). Structural ≈ 43, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure_illegal (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 0.80*43 + 0.20*40 = 42.4, then Illegal-deck cap applied via modifier to 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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

• Dark World core is fully present, with Reign-Beaux, Snoww, Ceruli, Grapha, and Sillva at 2 to 3 copies
• Archetype core group has about a 0.91 chance of at least one copy in an opening 5-card hand
• Multiple searchers (14 searcher-text cards) and self-discard starters give redundant access
• Three hand traps plus Harpie's Feather Duster and Heavy Storm provide some interaction

Weaknesses

• Four Forbidden OCG cards make the list illegal
• No side deck, so no post-side plan and no answer to changing metagames
• Starters at 3 copies have only about a 0.24 chance of appearing in a 5-card hand
• No recorded combo boards, so ceiling and floor cannot be measured
• Thin floodgate and negation coverage

Critical choke points

• Illegal Forbidden cards in the main and Extra Decks; the list cannot be played in OCG as built
• Dependence on Dark World monsters in the GY for recursion, with no alternative route if the GY is emptied
• Knightmare and Number 60 Extra Deck slots are wasted if removed without replacement

Recommended changes

Evidence & confidence

• Verified: Legality: 57 main, 15 extra, 0 side; four Forbidden cards over the limit (BanList OCG); Four Limited cards run at 1 copy, which is legal; Archetype core group: 21 copies in deck; exact-name purity 26.4%
• Inferred: D1 consistency estimates from hypergeometric draw tables (3-copy starter about 0.24 in a 5-card hand); Brick and resilience reads from card text and copy histogram; Interaction quality read from hand traps and removal text; Going-first and going-second power estimates
• Provisional: Meta Power is null; no dated metagame sample supplied; D13 matchup and format fit based on archetype context only
• 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 in YGOVN (going-first/second, matchup, brick/starter rates) Meta Power is Provisional unless a dated metagame sample is supplied No side deck, so post-side performance cannot be assessed
