Millennium Deck #767234 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Exodia (5-piece Forbidden One win)
• Format: ocg

Legality

Main 40 / Extra 6 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Assemble the five Forbidden One pieces (Exodia + four limbs) in hand for an instant win (Inferred: low hypergeometric odds, 1 copy each).; Grind advantage through Millennium Ankh, Shield of the Millennium Dynasty and Sengenjin continuous-spell searches, then convert with Nibiru, Heart of the Blue-Eyes and Extra Deck Link/Fusion boards (Inferred).
• Turn 1 (going first): Open a Millennium starter or searcher, place a Continuous Spell engine, and hold a hand trap (Ash, Ghost Belle, Veiler) for the opponent's first activation.
• Turn 2 (going second): Use hand traps (Infinite Impermanence, Ghost Ogre, Effect Veiler, Ghost Belle) to stop the opponent's first board, then rebuild through the engine.
• Recovery: Recover through searchers (Sengenjin, Golem, Heart of the Blue-Eyes) and Ghost Belle GY recursion once the hand traps are spent (Inferred).
• After siding: Not assessable: the deck runs no Side Deck, so there is no post-side plan.

Why it scores here

The deck reliably opens a Millennium engine: the archetype core group has about 98% odds of at least one copy in a five-card opening hand, and about 82% for at least one searcher, so the first turns are usually functional (Inferred from hypergeometric estimates). Its interaction density is the strongest part of the system, with hand traps and negates (Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Belle, Ghost Ogre) giving about 98% odds of at least one hand trap when going second. Conversion is weak on the evidence supplied: there are no recorded boards, no guides, and no tournament link, so the combo ceiling and median are text-only inference and stay low. The Exodia win condition needs five single-copy pieces together, which is unlikely in practice. The list is illegal in OCG because it runs three Ash Blossom & Joyous Spring against a limit of two, so the legality cap holds the score at 25. The score comes from consistency, interaction, and resilience on the system, not from the Millennium archetype's popularity and not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary, not a numeric blend. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: legality cap (Illegal) (-18.6); banlist exposure (-4); dependence on one Extra-Deck card (-2). Final formula: No reliable metagame: 0.80*Structural(52) + 0.20*TournamentReliability(40) = 49.6, then modifiers (-6) gives 43.6; the Illegal-deck cap sets Final to 25 (theoretical/structural-only, not a normal Final Contextual score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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

• Very high archetype core access (≈98% for at least one core card in an opening five).
• Dense interaction: hand traps and negates answer the opponent's first board on either turn order.
• Extra Deck covers Link and Fusion routes beyond the Exodia win.

Weaknesses

• Illegal list: three Ash Blossom & Joyous Spring exceed the OCG limit of two.
• Exodia 5-piece win is single-copy and very unlikely in a normal game.
• No Side Deck, so no post-side adaptation.
• Eighteen hand traps and tech slots risk dead cards when the engine is absent.

Critical choke points

• Exodia win requires all five Forbidden One pieces in hand at once; no redundant route.
• Continuous Spell engine (Ankh, Shield, Sengenjin, Golem) depends on the Millennium pieces being in hand.

Recommended changes

Evidence & confidence

• Verified: Main 40 / Extra 6 / Side 0 falls within OCG size rules (main 40–60, extra 0–15).; Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited OCG limit of 2 (illegal).; Exodia pieces and S:P Little Knight are Limited and run at 1 copy each (legal).; Hand trap count 18 and negation text count 13 from the card scaffold.
• Inferred: Archetype core ≈ 0.98 and searcher ≈ 0.82 at-least-one odds from hypergeometric estimates.; Interaction quality and going-second hand-trap density from card text.; Exodia 5-piece win is unlikely in practice.
• Provisional: Meta fit and matchup coverage: no dated metagame or tournament data.
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot records absent. No win-rate telemetry in YGOVN (going-first/second, matchup, brick/starter rates). No guides attached for the archetype. Meta Power is provisional and set to null.
