Gem-Knights Deck #756557 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Fusion Summon a high-ATK Gem-Knight Fusion boss (Lady Brilliant Diamond 3400, Master Diamond 2900, Rose Diamond 2700) off Brilliant Fusion or Gem-Knight Dispersion, then attack through the board; Gem-Knight Topaz double attack and Gem-Knight Ruby ATK growth, supported by Mulcharmy draw and Pot of Sloth card advantage
• Turn 1 (going first): T1 Gem-Knight Quartz or Nepyrim searches a Gem-Knight, then Brilliant Fusion or Dispersion Fusion Summons a boss from the Extra Deck; Lightning Storm or Illusion Gate is held for the opponent's board
• Turn 2 (going second): Hold Maxx C and Forbidden Droplet for the opponent's first summon or activation, then use Gem-Knight Hollowcore (GY banish, Quick Effect) or Super Polymerization to rebuild a Fusion boss
• Recovery: Gem-Knight Fusion and Phantom Quartz re-search and recur Gem-Knight cards from the GY; Pot of Sloth and Mulcharmy draw refill the hand once the board is cleared
• After siding: No side deck in Master Duel; no post-side plan exists in this format, so the deck's adaptability rests on its 11 tech cards being live in the main deck

Why it scores here

The deck reliably opens a Fusion starter: the archetype core (13 copies) has an estimated 0.88 chance of at least one copy in a 5-card opening hand, and 11 searcher-text cards add redundant access to Gem-Knight pieces (Inferred). Its ceiling comes from the Gem-Knight boss suite, which includes three 2700+ ATK fusion monsters and Topaz's double attack, so the deck can close a board quickly once a boss lands. Conversion is weaker than the ceiling suggests: no parseable recorded boards exist, so the median output is an inference, and 11 tech/dead-on-empty-board cards (Heavy Storm, Feather Duster, Triple Tactics, Illusion Gate, Lightning Storm) raise brick risk. Interaction is broad (5 negation-text and 14 removal-text cards) but thin on hand traps (Maxx C only) and has no floodgate. Popularity and archetype usage were not counted as power, and the score comes from consistency, closing power and interaction read on the system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Combo secondary; no 50/50 blend applied, Midrange weights used directly. Structural ≈ 58, Going First ≈ 61, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: Off-archetype draw engine conflict (-3); Dead tech in hand (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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

• Fusion starter redundancy: 6 Brilliant Fusion and Dispersion copies plus Scatter Fusion
• Searcher density (11 searcher-text cards) keeps the Gem-Knight core accessible
• High-ATK boss suite with Topaz double attack gives a strong closing line

Weaknesses

• Eleven tech and conditional cards raise brick and dead-card risk
• Only one hand trap and no floodgate
• No side deck in Master Duel, so no post-side adaptation
• Mulcharmy draw engine conflicts with a fusion engine that needs cards in hand

Critical choke points

• Single copies of Gem-Knight Fusion and Lightning Storm limit recovery routes
• Extra Deck boss access depends on Brilliant Fusion and Dispersion, which need a material board

Recommended changes

Evidence & confidence

• Verified: Legal: 40 main, 15 extra, 0 side within Master Duel size rules; Limited: Feather Duster, Heavy Storm and Maxx C at 1 copy each (legal); Super Polymerization Semi-Limited at 2 copies (legal); Usage stats: 24% of archetype core cards present (6 of 25)
• Inferred: P(>=1 archetype core in opening 5) ~0.88; P(>=1 Brilliant Fusion in opening 5) ~0.34; Brick risk from 11 tech and conditional cards; Boss ATK line supports closing power; Structural and going-first/second estimates from the rubric
• Provisional: Meta Power is null (no dated metagame sample); D12 post-side score (no side deck in format); D13 matchup and format fit (no tournament context)
• 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 (going-first/second, matchup, brick/starter rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null in the export
