Gem-Knights Deck #774773 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Fusion Summon a Gem-Knight Fusion (Lady Brilliant Diamond, Master Diamond Dispersion, Lady Rose Diamond) and attack with 2500-3400 ATK bodies; Link and Fusion chains through Gem-Knight Phantom Quartz and Gem-Knight Master Diamond; Mulcharmy draw pressure
• Turn 1 (going first): Gem-Knight Dispersion or Quartz/Nepyrim search into a Fusion Summon via Brilliant Fusion or Fusion, then extend with Phantom Quartz and Seraphinite
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Ghost Ogre and Droll to interrupt the opponent's first engine, then rebuild a Fusion board
• Recovery: Gem-Knight Fusion and Hollowcore recurse from the GY; Mulcharmy Fuwalos and Purulia refill hand after an empty board
• After siding: Not evaluable: side_count is 0, so no post-side plan exists

Why it scores here

The deck's Gem-Knight core is dense (28 Gem- copies, about 98% chance of at least one in a 5-card opening hand), so the engine usually starts. Its fusion and link finishers reach strong bodies, and ten hand traps plus Forbidden Droplet and Harpie's Feather Duster give it real interaction on the system. Output is unmeasured because no recorded boards exist, so the combo ceiling and median are text-only inferences. The list is illegal (two cards run 3 copies against a limit of 2) and has no side deck, which caps the result as a theoretical, structural-only read. Popularity and archetype usage did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54.8, Going First ≈ 56, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy-limit cap (-10); No side deck (-2). Final formula: Illegal: no normal Final score. Structural 54.8 and TR 45 give 0.80*54.8+0.20*45 = 52.8 before modifiers; modifiers total -12; capped at 35 as theoretical/structural-only. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense Gem-Knight core with a high chance of a live opening hand
• Ten hand traps plus negation and removal tech give broad interaction
• Extra Deck covers Fusion and Link bodies with high ATK

Weaknesses

• Two cards over the OCG copy limit makes the list illegal
• No side deck, so no post-side adaptation
• Low archetype purity; 70 main-deck copies are off-archetype or generic

Critical choke points

• Fusion Summon routes depend on Gem-Knight Fusion or Brilliant Fusion, both 1-copy cards
• Lady Brilliant Diamond and Master Diamond depend on a Fusion Summon line

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom and Super Polymerization exceed the OCG limit of 2; Main 55 and Extra 15 are within OCG size rules; Only 2 Limited cards are present, each at 1 copy; Gem- archetype core is 28 copies
• Inferred: Opening-hand consistency from hypergeometric draw odds; Interaction density from hand-trap and negation text; Going-first and going-second estimates
• Provisional: Meta Power (no dated metagame sample); Matchup fit
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: no archetype meta-share or pilot record No win-rate telemetry for this deck No side deck, so post-side performance cannot be assessed Meta Power is Provisional without a dated metagame sample
