Gem-Knights Deck #750726 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 61/100 (±10 · Confidence: Low)

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

Legality

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

Identity & game plan

• Win condition: Fusion Summon Gem-Knight Fusion Monsters with high ATK (Lady Brilliant Diamond 3400, Master Diamond Dispersion 3000, Master Diamond 2900, Garura, Ruby) and attack through a board cleared by the deck's staple removal.; Link and Fusion follow-ups (Gem-Knight Phantom Quartz, Lady Rose Diamond, Lady Lapis Lazuli) that add board presence and recurring damage or protection.
• Turn 1 (going first): Turn 1 Normal Summon a Gem-Knight searcher (Quartz, Nepyrim or Armadillo) to add a Fusion spell (Gem-Knight Fusion, Brilliant Fusion, Scatter Fusion, Dispersion or Absorb Fusion), then Fusion Summon a Gem-Knight Fusion Monster from the Extra Deck on turn 2.
• Turn 2 (going second): Use hand traps (Nibiru, Red Reboot) or a board wipe (Dark Hole, Raigeki, Heavy Storm, Lightning Storm) to clear the opponent's first board, then rebuild through the Fusion enablers.
• Recovery: Recurse Gem-Knight Fusion from the Graveyard (banish one Gem-Knight from the GY), rebuild the searcher chain from the Deck, and use Gem-Knight Phantom Quartz to add a Fusion spell.
• After siding: No sideboard is run (side_count 0), so there is no post-side plan in this list.

Why it scores here

The deck reliably opens a Fusion starter: 15 copies of Gem-Knight searchers and a Fusion-enabler suite (Gem-Knight Fusion, Brilliant Fusion, Scatter Fusion, Dispersion, Absorb Fusion, Super Polymerization) give an estimated ~82% chance that the 11-copy archetype core is in a 5-card opening hand (Inferred). The end-board is strong on paper: Dark Hole, Raigeki, Heavy Storm, Harpie's Feather Duster, Lightning Storm, Red Reboot, Forbidden Droplet and Nibiru cover monsters, spells and traps, and Fusion Summons in the Extra Deck give the closing power. The main penalties are the lack of recorded boards (no combo floor, median or ceiling can be measured), a brick proxy near 18% for hands with no core card, and only 15 of 40 main-deck cards carrying the Gem- archetype name, so much of the deck is staples rather than engine. Popularity was not credited: archetype core stats confirm the list is real, not strong. The score is built from the system dimensions, not an average of the individual card scores. Meta Power is null (provisional) because no dated metagame sample exists.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63, Going First ≈ 70, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ — · full-brick estimate ≈ 0.18 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High estimated chance that the archetype core is live in the opening hand, supported by 12 searcher-text cards
• Fusion-enabler suite gives several independent routes to the same Extra Deck bosses
• Broad removal and negation coverage across monsters, spells and traps, including going-second board clears
• Extra Deck coverage is strong: 12 of 15 Extra cards carry the Gem- name and include several 2900 to 3400 ATK bosses

Weaknesses

• Only 15 of 40 main-deck cards carry the Gem- archetype name; roughly 25 cards are staples or tech that do not advance the engine
• No recorded boards, so the combo floor, median and ceiling cannot be measured
• Several non-engine staples can be dead in hand, and the brick proxy sits near 18%
• No sideboard, so post-side adaptation is unavailable

Critical choke points

• The first Fusion Summon depends on a Fusion spell or a Gem-Knight searcher reaching hand; the core-group miss rate is about 18% in a 5-card hand
• Gem-Knight Fusion and Absorb Fusion are the main recursion for the engine, so losing them to hand traps or an early removal board removes the rebuild path

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 within the master-duel size rules (main 40-60, extra 0-15, side 0-15); All four restricted cards are at or below legal copies (Harpie's Feather Duster 1, Heavy Storm 1, Red Reboot 2, Super Polymerization 2); Composition: 12 Fusion, 2 Link, 1 Xyz in the Extra Deck; 27 Gem- named cards across Main and Extra; usage_statistics: archetype core group (11 copies) and searcher group (12 copies) as reported by the evidence pack; Guide snippet (Vietnamese, 1187) describes the old FTK line as cumbersome and brick-prone with more hand traps now
• Observed: Guide text reports the deck's current support splits opponent Main Phase damage and that the combo is cumbersome
• Inferred: Core-group hit probability ~0.82 and brick proxy ~0.18 (hypergeometric); Going-second hand-trap group ~0.58 in a 6-card hand; Fusion route independence and recursion estimates (D5, D6); Interaction breadth scoring (D7) and going-second board breaking (D8) from card text
• Provisional: Meta Power is null; no dated metagame sample supplied; D12 side adaptability and D13 matchup fit are scored conservatively because there is no sideboard and no tournament context
• Data gaps: No parseable combos (total_combos 0): combo floor, median and ceiling are text-only inference, and confidence is Low for that reason usage_statistics in_this_deck flags are wrong for Extra Deck cards: nine core cards marked in_this_deck false (Mudragon of the Swamp, Gem-Knight Seraphinite, Gem-Knight Aquamarine, Gem-Knight Topaz, Gem-Knight Prismaura, Gem-Knight Master Diamond Dispersion, Gem-Knight Master Diamond, Gem-Knight Ruby, Gem-Knight Lady Brilliant Diamond) are present in the cards list at 1 copy each. The corrected core-present count is 15 of 25, not the reported 6 of 25 No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first, going-second, matchup, brick and starter rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null; the deck is identified by archetype and card list only
