Snake-Eye Deck #750633 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Level 8 boss monsters from the Fire King and Snake-Eye lines (Garunix Eternity, Snake-Eyes Flamberge Dragon, Snake-Eyes Doomed Dragon, Zombie Vampire) once the board is established; Link beatdown through Salamangreat, Promethean Princess and Decode Talker Heatsoul
• Turn 1 (going first): Open a Level 1 FIRE starter (Snake-Eye Ash, Snake-Eyes Poplar, Snake-Eye Oak, Fire King Kirin/Ulcanix) to search or special-summon a second Level 1 and reach a Level 8 boss or Link-3 by the second turn (Inferred, no recorded boards)
• Turn 2 (going second): Use the six-card hand with Ash Blossom, Infinite Impermanence and Dominus Impulse to interrupt the opponent's first board, then rebuild through Fire King or Snake-Eye recursion (Inferred)
• Recovery: Recover through GY-based specials: Sacred Fire King Garunix, Legendary Fire King Ponix, Snake-Eye Oak and Fire King High Avatar Garunix from the GY (Inferred)
• After siding: No side deck in Master Duel format; no post-side plan applies

Why it scores here

The list is Illegal in Master Duel because it runs three copies of Fire King High Avatar Kirin against a Semi-Limited limit of two, so the score is theoretical and structural only and is capped low. Structurally the deck can open a Level 1 starter in roughly 80% of five-card hands via the archetype-core group (Inferred), and its searchers (Snake-Eye Ash, Snake-Eyes Poplar, Snake-Eye Oak, Legendary Fire King Ponix) give it a reasonable first-turn route. Interaction is the strongest area: six hand traps and ten negation-text cards give it real going-second pressure, and the Level 8 bosses and Links give a credible end-board. The deck is held back by a split identity: only 7 of 60 cards are exact Snake-Eye names and 14 of the 23 archetype core cards are absent, so Fire King and Snake-Eye engines compete for the same hand. No recorded boards exist, so floor, median and ceiling are text-only inference, and no meta-share or win-rate data supports any popularity claim. The score was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: 0.85 Midrange / 0.15 Toolbox (Midrange weights used for structural score). Structural ≈ 51, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 47. Modifiers: engine conflicts (-6); banlist exposure / illegal copy count (-6). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal deck capped low, theoretical only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Dense Level 1 starter/searcher package with 12 searcher-text cards
• Six hand traps plus ten negation-text cards for going-second interaction
• Multiple Level 8 and Link-4 boss options with 2700-3000 ATK
• Redundant GY recursion through Fire King and Snake-Eye specials

Weaknesses

• Illegal in Master Duel: Fire King High Avatar Kirin run at 3 copies (limit 2)
• Split engine: only 7 exact Snake-Eye names and 14 of 23 archetype core cards absent
• 27 distinct main-deck cards with many one-copy tech slots reduces repeatability
• No combo evidence, so the ceiling and median cannot be checked against real boards

Critical choke points

• The 3-copy Kirin overage makes the list unplayable as submitted until one copy is removed
• Opening a Level 1 FIRE starter in hand is the single point of failure for going-first lines

Recommended changes

Evidence & confidence

• Verified: Deck is 40 main / 15 extra, within Master Duel size rules (40-60 / 0-15); Fire King High Avatar Kirin run 3x vs legal 2x (Semi-Limited); Archetype purity 12.7% exact-name; 7 Snake-Eye exact-name copies; Archetype core group: 11 copies in deck, 39.1% core present (9 of 23); Hypergeometric probabilities from the resolved Main Deck list
• Inferred: At-least-one-starter probability ~0.82 in going-first hand (Inferred from hypergeometric estimate); Going-second hand-trap group p(>=1 in 6) ~0.65 used for D8; Starter/engine split and resulting brick rate; Going-first and going-second plans and the recovery plan; D1-D14 dimension scores and the structural score
• Provisional: Meta Power (no dated metagame sample supplied); Tournament reliability and matchup fit (no tournament link or win-rate telemetry)
• Data gaps: no combos supplied - combo floor/median/ceiling is text-only inference no tournament link - archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN - going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck is Illegal (Kirin copy overage), so the final score is a capped theoretical estimate Side deck does not exist in Master Duel format; D12 cannot be measured
