GMX Deck #764623 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

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

Legality

Main 52 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Fusion Summon GMX - COMPREX, GMX - ALLOS or GMX - VELOX off Dinosaur and GMX bodies, then attack through the boards with 3000+ ATK monsters; Transcendosaurus Exaraptor and Drillygnathus plus Dino Xyz/Link extenders for a second board
• Turn 1 (going first): Normal Summon a GMX starter (Partner Selandea, Chairman Kimridge or Associate Noma), search with Researcher Selande or Fossil Dig, then Fusion Summon a GMX Fusion Monster through the Dino board
• Turn 2 (going second): Hand traps (Ash Blossom, D.D. Crow, Anti-GMX Final Experiment) on the opponent's first meaningful activation, then rebuild a Dinosaur board through GMX 55th Experiment Report or Applied Experiment #55
• Recovery: Returned Dino Daneen and Mulcharmy Fuwalos for card advantage; Jurassic Power and Fossil Dig re-search a Dinosaur, and Lab #5 resets the GMX Spell/Trap line
• After siding: Not evaluable: the deck runs no Side Deck, so no post-side adjustment is recorded

Why it scores here

The deck reliably opens a GMX starter: the archetype core has about a 97% chance of at least one card in a 5-card opening hand (Inferred, hypergeometric). It converts that opening into Fusion Summons of GMX - COMPREX, ALLOS and VELOX, which give 2700 to 3700 ATK bodies, and it keeps a dense interaction suite (Ash Blossom, D.D. Crow, Anti-GMX Final Experiment, Evolzar Dolkka and Laggia) to contest the opponent's turn. Floor and median output are uncertain because no recorded boards exist, so the combo component is scored from text only. Legality caps the result: Ash Blossom is over the copy limit and the Extra Deck is 18 against a maximum of 15, so the score is a theoretical, structural read. Popularity (GMX archetype share) was not used as a score input, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 61, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Copy-limit violation (-6); Extra Deck overflow (-6). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*61 + 0.20*50 - 12 = 46.8, then capped to 40 because the deck is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense GMX starter and searcher package gives a high opening-hand engine chance
• Hand-trap and negation suite (Ash, Crow, Anti-GMX, Dolkka, Laggia) covers both turns
• Multiple 2700–3700 ATK Fusion and Link closers with several independent routes

Weaknesses

• Illegal as built: Ash Blossom copy limit and Extra Deck size are both violated
• No Side Deck, so no post-side plan or best-of-3 adaptation
• Off-archetype Dinosaur filler and 40 off-archetype copies dilute the engine
• Fusion lines cost LP (400 per excavated card on Velox and Applied Experiment)

Critical choke points

• GMX Fusion Monster in the Extra Deck: several lines require a specific Fusion Summon
• Ash Blossom copy count: the list cannot be submitted as built
• Dinosaur board requirement for the Fusion enders

Recommended changes

Evidence & confidence

• Verified: Main size 52 is legal (40–60); Extra Deck 18 exceeds the OCG maximum of 15; Ash Blossom & Joyous Spring is run 3 times against a limit of 2; Card stats and text as listed in evidence
• Observed: Archetype core inclusion rates from usage_statistics (GMX 55th Experiment Report 62.5%, GMX Associate Noma 62.5%)
• Inferred: 97% chance of at least one archetype core card in a 5-card hand; Going-first and going-second plans and their route redundancy; Interaction and closing read from card text
• Provisional: Meta Power (null) — no dated metagame sample
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry; going-first and going-second splits are not measured No Side Deck recorded (0 cards) Illegal list: the score is a theoretical, structural-only read
