Gem-Knights Deck #761558 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±7 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion Summon Gem-Knight boss monsters (Lady Brilliant Diamond 3400 ATK, Master Diamond Dispersion, Gem-Knight Master Diamond) through Brilliant Fusion, Dispersion, Absorb Fusion and Gem-Knight Fusion; Off-archetype Fusion and Link bosses (The Dragon that Devours the Dogma, Starving Venom Fusion Dragon) and Phantom Quartz link pressure
• Turn 1 (going first): Normal Summon Gem-Armadillo or Gem-Knight Nepyrim to search a Gem-Knight, then set up a Fusion Summon (Brilliant Fusion or Dispersion) from Deck or hand materials, with Ash Blossom and Droll & Lock Bird held as backup
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Ghost Belle, Ghost Ogre, Skull Meister, Maxx C, Infinite Impermanence, Nibiru) to break the opponent's setup, then rebuild through Fusion Summons
• Recovery: Recur Gem-Knight Fusion and Absorb Fusion from the Graveyard, Dispersion from the Deck, and use Hollowcore's Graveyard banish to keep interaction running
• After siding: No side deck is registered (side_count 0); Master Duel has no post-side plan to evaluate, so none is scored

Why it scores here

The deck reliably opens a functional plan: six 3-copy searchers and summoners (Armadillo, Quartz, Nepyrim, Brilliant Fusion, Ash, Fuwalos) give P(at least one searcher in a 5-card opening hand) of about 0.88 (Inferred), and the Gem-Knight archetype core has about a 0.95 chance of at least one card in the opening hand. Conversion into pressure comes from Fusion Summons into 3000+ ATK bosses (Lady Brilliant Diamond, Master Diamond Dispersion), but the recorded combo evidence is empty, so the ceiling is text-only inference. Survival is the deck's strongest area: 11 hand-trap-flagged cards, 9 negation-text cards and Graveyard recursion (Gem-Knight Fusion, Absorb Fusion, Hollowcore) keep interaction running after disruption, and the going-second score rests on that hand-trap density. Popularity and the usage-stat core did not earn points, and card scores were not averaged; the score was built on the system, and Meta Power stays provisional because no dated metagame sample exists. Fuwalos x3 and Book of Eclipse add little to the engine and lower the efficiency score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 65, Going First ≈ 66, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*64.9 + 0.20*62 = 64.4, then modifiers -2 = 62.4 -> 62

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Redundant searchers (13 searcher-text cards; P(>=1) about 0.88 in hand)
• Dense hand-trap and negation layer (11 hand traps, 9 negation texts) for going second
• Graveyard recursion (Gem-Knight Fusion, Absorb Fusion, Hollowcore) for resilience
• High-ATK Fusion bosses (Lady Brilliant Diamond 3400, Master Diamond Dispersion 3000)

Weaknesses

• No recorded combo boards, so ceiling and median are inferred from text only
• Mulcharmy Fuwalos x3 and Book of Eclipse are off-engine
• Several Extra bosses need non-Gem materials, which weakens Extra coherence
• Multi-step Fusion lines are costly and hard to pilot

Critical choke points

• Fusion Summon enablers: Brilliant Fusion (3 copies) and Dispersion (2) gate most boss lines
• Searchers and summoners (Armadillo, Nepyrim, Quartz) gate the Gem-Knight Fusion materials

Recommended changes

Evidence & confidence

• Verified: Legal under master-duel rules: 40 Main, 15 Extra, 0 Side; Maxx C 1/1 Limited, Droll & Lock Bird 2/2 Semi-Limited, Super Polymerization 1/2 Semi-Limited; Card texts for the listed cards (from the evidence excerpts)
• Observed: Usage statistics: Droll & Lock Bird, Super Polymerization, Book of Eclipse and Forbidden Droplet are 100% inclusion in this archetype
• Inferred: P(>=1 searcher in hand) 0.877 and archetype core 0.949 from hypergeometric draws; Ceiling and engine read from Fusion text and boss stats; Interaction and going-second breadth from hand-trap and negation text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data); D12 side adaptability (no side deck)
• 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 are absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample usage_statistics in_this_deck flags report false for Extra-Deck cards the deck does run (e.g. Gem-Knight Seraphinite, Lady Brilliant Diamond, Mudragon, Sea Monster of Theseus). core_present_pct 48 is unreliable and was not used as evidence archetype_purity exact-name metric (0%) does not reflect the Gem- prefix family
