Gem-Knights Deck #773798 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±12 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fusion Summon a Gem-Knight or Darklord boss (Gem-Knight Lady Brilliant Diamond, The First Darklord, Darklord Eveningstar, Luce the Dusk's Dark) from the Extra Deck; Recursion-driven grind through Darklord Contact, Banishment of the Darklords and Gem-Knight Hollowcore in the GY
• Turn 1 (going first): Open a Darklord or Gem-Knight starter (Djehuty, Nepyrim, Indulged Darklord, Gulgolet), search via Banishment or Nepyrim, and fuse into a 3000+ ATK boss through Mutiny in the Sky or Darklord Dance
• Turn 2 (going second): Use the Herald hand traps (one of them over the copy limit) and the Buio/Hollowcore negations to stop the opponent's first board, then fuse off the top of the Deck
• Recovery: Darklord Contact and Gem-Knight Hollowcore recycle GY monsters; Mutiny in the Sky returns from the GY by sending one Fiend or Fairy
• After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan

Why it scores here

The deck reliably opens a functional starter: the Darklord and Gem-Knight searchers (22 searcher-text cards) give a P(at least one searcher in a 5-card hand) of about 0.99, and the archetype core group has about a 0.64 chance of at least one card in hand. Conversion is credible on paper, since the Extra Deck holds several 3000+ ATK fusions, but no recorded boards exist, so the ceiling and median are text-only inferences. Interaction is layered through 12 negation and 12 removal texts, with the Herald hand traps providing the disruption, but the Herald copies over the limit make the list illegal. The deck's structural score is about 54 and its Final is about 52 before the -12 illegality and banlist-exposure modifier. The score comes from consistency, median output and interaction at system level, not from averaging card scores, and not from Gem-Knights being a known archetype: usage stats confirm the list is real but earn no power points. Because the list is illegal, this is a theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy-limit violation and banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(54) + 0.20*TournamentReliability(45) = 52.2, then -12 modifiers, capped at 40. Illegal deck: theoretical/structural-only read.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · 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 and recursion text (22 searchers, Darklord Contact, Banishment)
• High-ATK Extra Deck fusion ceiling
• Layered negation and removal (12 each) plus 3 hand traps

Weaknesses

• Illegal: Herald of Orange Light run 3 times against a limit of 1
• No Side Deck, so no best-of-3 adaptation
• Low exact-name archetype purity (0%) with three sub-archetypes diluting the engine
• Fusion-material dependence with no recorded boards

Critical choke points

• Fusion Summon requires the correct materials in Deck or hand; a missing Brilliant Fusion or Mutiny line stalls the plan
• The Herald hand traps are the main disruption, and two of the three copies are illegal

Recommended changes

Evidence & confidence

• Verified: Illegal: 3 copies of Herald of Orange Light against a Limited limit of 1; Main 40 / Extra 15 / Side 0 sizes; Archetype purity 0% with 55 off-archetype copies; Searcher text count 22; negation text count 12; removal text count 12
• Inferred: Engine accessibility P(searcher in hand5) ≈ 0.99; Going-second hand-trap coverage ≈ 0.39; Fusion-based ceiling from Extra Deck ATK values
• Provisional: Meta power (no dated metagame sample); Matchup and format fit (archetype usage only)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: no meta-share and no per-pilot match record No Side Deck: post-side performance cannot be assessed No win-rate telemetry exists in YGOVN for this deck
