Gem-Knights Deck #772190 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±7 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Midrange
• Format: ocg

Legality

Main 56 / Extra 14 / Side 0 — status: Legal with warning.

Identity & game plan

• Win condition: Gem-Knight Fusion boss monsters: Lady Brilliant Diamond (3400 ATK), Master Diamond Dispersion (3000), Master Diamond (2900, gains ATK per Gem- monster in GY), with Topaz double attack as secondary closing; Gem-Knight Topaz and Ruby as additional attackers; Gem-Knight Hollowcore as negation and recursion body
• Turn 1 (going first): Open with a searcher-text card (Nepyrim, Quartz, Armadillo, Gem-Knight Phantom Quartz via Link) to find a Gem-Knight Fusion route, then Fusion Summon via Gem-Knight Dispersion or Gem-Knight Fusion into a 3-material boss
• Turn 2 (going second): Use hand traps (Ghost Belle and Haunted Mansion, Nibiru, Infinite Impermanence, Droll and Lock Bird) and Hollowcore negation to slow the opponent, then convert through the same Fusion routes
• Recovery: Re-fuel through Gem-Knight Fusion recursion from the Graveyard, Gem-Knight Hollowcore banish-for-effect, Foolish Burial, and searchers; Mulcharmy draw effects are conditional on an empty field
• After siding: None: the side zone in the export is empty, so there is no post-side plan

Why it scores here

The deck reliably opens into a searcher-driven Gem-Knight Fusion plan: the searcher-text group hits at least once in roughly 80% of going-first opening hands, and the Extra Deck supplies 10 Fusion and 4 Link options with several 3-material bosses (Inferred). Its ceiling is strong because Lady Brilliant Diamond, Master Diamond Dispersion and Master Diamond supply 2900 to 3400 ATK closing power, and seven hand traps plus about ten negation-text cards give layered interaction. The score is held back by a 56-card main deck with 41 non-Gem main copies, three Shaddoll Fusion copies that have no Shaddoll Fusion Monster to summon in the Extra Deck, a conditional Lightning Storm and Mulcharmy engine, and an empty side deck. Popularity and usage stats were not credited; no combo boards exist, so the floor and median are text-only and scored conservatively, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 61.9, Going First ≈ 60.5, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: engine conflicts (-3); banlist exposure (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-5)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.8 · 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 searcher-text package (15 cards) with several independent starters
• Strong Extra Deck closing options at 2900 to 3400 ATK
• Layered interaction: 7 hand traps plus 10 negation-text cards
• Extra Deck covers 10 Fusion and 4 Link routes

Weaknesses

• Three Shaddoll Fusion have no Shaddoll Fusion Monster to summon in the Extra Deck, making them near-dead
• 56-card main with 41 non-Gem copies dilutes the engine
• No side deck: no post-side plan at all
• No combo evidence, so floor and median are unmeasured

Critical choke points

• Only one Gem-Knight Fusion and one Brilliant Fusion: each is a single-copy route into the Fusion bosses
• Fusion bosses need 3 Gem-Knight materials, so a starter hand without enough Gem- cards stalls
• Heat Wave and Different Dimension Ground actively hinder the deck's own Effect Monsters and Graveyard

Recommended changes

Evidence & confidence

• Verified: Main 56 and Extra 14 are within the OCG size rules; Side 0 is within the 0-15 range; Seven Limited cards each run at the legal 1-copy limit; Extra Deck contains no Shaddoll Fusion Monster, so Shaddoll Fusion x3 cannot Fusion Summon a target; Gem- family holds 27 of 70 copies; 41 of 56 main copies are non-Gem
• Observed: Archetype usage stats: Gem-Knight Dispersion, Fusion, Brilliant Fusion, Nepyrim at 50 to 87.5 percent inclusion
• Inferred: Starter access about 0.80 on a going-first 5-card hand; Hand-trap access about 0.57 on a going-second 6-card hand; Combo ceiling from card text; closing power from ATK and text
• Provisional: Meta Power (null) and format fit (D13 neutral 50); Median and floor (D4) with no combo boards
• 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 One main-deck passcode (20366274) did not resolve and was counted as main Side zone empty in the export: unknown whether a side was submitted Usage-statistics in this deck flags contradict the Extra list: Gem-Knight Lady Rose Diamond (55610199), Master Diamond Dispersion (25342956), Prismaura (93379652), Aquamarine (13108445), Seraphinite (3113836) and Phantom Quartz (24484270) are present in the Extra Deck but flagged not in deck, so core-card presence 53.3 is unreliable No win-rate telemetry exists in YGOVN: going-first and going-second splits and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null
