Millennium Deck #772109 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Exodia the Forbidden One line: all five Forbidden One pieces, or The Unstoppable Exodia Incarnate (x3) summoned via Millennium Ankh; Millennium Continuous Spell engine (Shield of the Millennium Dynasty, Sengenjin, Golem that Guards the Millennium Treasures) and Heart of the Blue-Eyes searching Millennium Ankh
• Turn 1 (going first): Open a Millennium Continuous Spell or Heart of the Blue-Eyes, search Millennium Ankh, and look for the Forbidden One set; protect with Ash Blossom and Infinite Impermanence
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Sister, Droll & Lock Bird, Infinite Impermanence) to stop the opponent's first combo line, then rebuild the Millennium engine
• Recovery: Recover through Heart of the Blue-Eyes and Golem/Sengenjin continuous spell routes; Forbidden One pieces are single-copy, so recovery is limited
• After siding: No side deck is registered (Side Deck size 0), so there is no post-side plan

Why it scores here

The list is illegal: Ash Blossom & Joyous Spring and Super Polymerization are each run three times against a two-copy Semi-Limited limit, so this is a theoretical, structural-only score and it is capped low. Structural power comes from a Millennium engine that can reach Millennium Ankh through Heart of the Blue-Eyes (about 5% of opening hands hold both, Inferred), with a dense hand-trap layer (ten hand traps plus Forbidden Droplet, Infinite Impermanence and Harpie's Feather Duster) that gives real interaction. The Exodia and Unstoppable Exodia win paths need all five Forbidden One pieces, which are singletons, so they are rare rather than typical; about 62% of five-card hands contain none of them (Inferred). The score does not come from popularity, since the archetype usage stats only confirm the core is run, and it is not an average of card scores. No combos or tournament data exist, so the floor and median are unmeasured and confidence is Low.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 40, Going First ≈ 35, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Illegal copy-limit violation (-8). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; modifier -8 for Illegal copy-limit violation): 0.80*40 + 0.20*30 - 8 = 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ 0.05 · 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

• Millennium engine has several searchers (Heart of the Blue-Eyes to Ankh, Shield, Sengenjin, Golem)
• Dense interaction: ten hand traps plus Forbidden Droplet, Infinite Impermanence, Harpie's Feather Duster and Lightning Storm
• Archetype core is present in about 93% of 5-card hands (Inferred)

Weaknesses

• Illegal as built: three copies each of two Semi-Limited cards
• Exodia and Unstoppable Exodia need all five singleton Forbidden One pieces, so the win is rare
• Three different engines (Millennium, Exodia, Exodd/Blue-Eyes side pieces) conflict for slots
• No side deck; no post-side plan
• Zero combo or tournament data, so the floor and median are unmeasured

Critical choke points

• All five Forbidden One pieces are required for the Exodia and Ankh lines
• Millennium Ankh must be reached through Heart of the Blue-Eyes or a searcher

Recommended changes

Evidence & confidence

• Verified: Copy-limit violations for Ash Blossom & Joyous Spring and Super Polymerization (3 run vs 2 legal); Main 57, Extra 15, Side 0 counts and size limits; Extra Deck breakdown: 8 Fusion, 5 Link, 2 Synchro; Exact-name archetype purity 15.3%; Zero side-deck cards
• Observed: Archetype usage stats: core cards present (76.5% of core)
• Inferred: Hypergeometric starter and hand-trap probabilities; Heart plus Ankh together in opening hand about 0.05; About 0.62 of 5-card hands contain no Forbidden One piece; Going-second hand-trap estimate about 0.70; Engine conflict between Millennium, Exodia and side archetypes
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second, matchup, brick or OTK rates Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal, so the score is structural-only and capped low
