Snake-Eye Deck #759679 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: master-duel

Legality

Main 44 / Extra 15 / Side 0 — status: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Field-dominating boss monsters from the Main Deck and Extra Deck (Snake-Eyes Flamberge Dragon, Vanquish Soul Caesar Valius, Underworld Goddess of the Closed World, Amphibious Swarmship Amblowhale) backed by Link monsters; Link-chain pressure through Knightmare Unicorn, Promethean Princess and the Charmer Links
• Turn 1 (going first): Open a Level 1 FIRE starter (Snake-Eye Ash, Snake-Eye Oak or Snake-Eyes Poplar) or a searcher, chain Snake-Eye and Diabellstar searches into a boss Special Summon. Starter access is thin (see probabilities), so going first is fragile
• Turn 2 (going second): Play through the opponent's board with Ash Blossom, Ghost Belle and D.D. Crow, then rebuild with Snake-Eye and Vanquish Soul searches into a boss. Hand traps are the strongest part of this plan
• Recovery: Recover via Snake-Eyes Flamberge Dragon from the GY/banish and Snake-Eye GY recursion through Original Sinful Spoils and Snake-Eye Oak
• After siding: Not evaluable: side_count is 0, so no post-side plan exists in this list

Why it scores here

The deck's core reliably reaches a searcher: P(at least one of 17 searcher-text cards in an opening hand of 5) is about 0.93, and 20 archetype-core copies give about 0.96 for at least one core card in hand (Inferred). Single-copy Snake-Eye starters are the weak point: Snake-Eye Ash has about 0.11 odds in a 5-card opening hand, so the engine is not reliably live on turn 1. Interaction is the clearest strength, with 10 hand traps and 7 negation texts, about 0.81 odds of at least one hand trap in a 6-card going-second hand (Inferred). Boss monsters at 2500 to 3000 ATK close games. Points were not earned from the archetype's popularity, and the score was not averaged from card scores. Three Limited cards and two Forbidden cards are over the limit, so the list is Illegal and the score is capped as structural-only.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (approx. 80/20). Structural ≈ 52, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-6); no_side_deck (-3); engine_conflict (-3). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*52 + 0.20*45 = 50.6; minus 12 context modifiers = 38.6; ILLEGAL cap applied (theoretical/structural-only) -> 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.11 · 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

• High searcher density (17 searcher-text cards) gives reliable access to the engine pieces
• 10 hand traps plus 7 negation texts give strong going-second interaction
• Several 2500 to 3000 ATK bosses close games
• The archetype core is widely run (usage stats), so the list is real and accessible

Weaknesses

• The list is Illegal: 3 Limited cards over the limit and 2 Forbidden cards plus 1 Forbidden Extra card
• Single-copy Snake-Eye starters give a low turn-1 starter rate
• No side deck
• Heavy off-archetype spread dilutes engine coherence
• 11 of 25 usage-stat core cards are present (44%)

Critical choke points

• Snake-Eye Ash is a single copy that gates the Level 1 FIRE engine on turn 1
• Forbidden Called by the Grave and Apollousa cannot be played, so the interaction and Extra routes both break

Recommended changes

Evidence & confidence

• Verified: Illegal status: Maxx C, Stake your Soul!, WANTED each at 3 copies vs 1 legal; Called by the Grave x2 and Apollousa and Bagooska are Forbidden; Main 44 and Extra 15, both inside master-duel size rules; side 0; Usage stats: 11 of 25 core cards present (44%); Card text and stats for all 40 distinct cards come from the resolved card data
• Inferred: Starter and searcher probabilities are hypergeometric estimates from the Main Deck; Interaction density and hand-trap odds from card text; Going-first and going-second estimates and the Combo primary-strategy classification
• Provisional: Meta Power (no dated metagame sample); D13 matchup fit (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 match record absent No win-rate telemetry: going-first and going-second splits, matchup and brick rates are Inferred or Unknown No side deck (side_count 0), so post-side performance is unscorable Meta Power is Provisional without a dated metagame sample Illegal list: the evaluation is structural-only and capped at 30
