GMX Deck #771370 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: ocg

Legality

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

Identity & game plan

• Win condition: GMX Fusion Monsters (GMX - COMPREX, GMX - ALLOS, GMX - VELOX, Evolved Daneen) and Dinosaur boss monsters (Ultimate Conductor Tyranno, Dogoran) supported by GMX searchers; Synchro and Xyz boss monsters from the Jurrac and Evolzar sub-archetypes (Jurrac Astero, Evolzar Laggia, Evolzar Dolkka)
• Turn 1 (going first): Excavate or search GMX/Dinosaur pieces through the searchers (GMX Researcher Selande, Fossil Dig, GMX Chairman Kimridge, Returned Dino Daneen) and convert them into a Fusion Summon; hold hand traps (Ash Blossom, Droll & Lock Bird) for the opponent's first interaction. Not tested against real boards.
• Turn 2 (going second): Use the hand traps (Ash Blossom, Nibiru, Droll & Lock Bird, Miscellaneousaurus) to disrupt the opponent's opening line, then rebuild from the searcher-driven Extra Deck access. Inferred from card text only.
• Recovery: Re-search via GMX Chairman Kimridge and Returned Dino Daneen after an interaction-heavy turn; Dinosaur recursion (Souleating Oviraptor, Miscellaneousaurus GY banish) is text-only and unverified.
• After siding: None: the deck registers 0 Side Deck cards, so there is no post-side plan.

Why it scores here

The deck reliably opens its GMX engine: the archetype-core group has P(at least one in a 5-card opening hand) ≈ 0.95 and the searcher text group ≈ 0.96 (Inferred hypergeometric estimates). Searchers and Dinosaur-recursion text give it resource regeneration. Interaction is substantial (7 hand-trap-tagged cards, 7 negation-text cards, 13 removal-text cards), and it has several Dinosaur and Fusion bosses with high ATK (COMPREX 3700, Tyranno 3500). Its score is capped, not earned: the list is Illegal because Ash Blossom & Joyous Spring is run 3 times against a limit of 2, and the deck runs no Side Deck. No combo, tournament, or win-rate data exists, so floor and median output are unknown. Popularity of the GMX archetype did not add points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53.6, Going First ≈ 56, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy-limit violation (-10); No Side Deck (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*53.6 + 0.20*40 - 12 = 38.9, capped at 35 because the list is Illegal (theoretical/structural-only score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• Core engine is highly accessible: archetype-core group ≈ 0.95 in a 5-card opening hand (Inferred)
• Searcher density (18 text cards) supports recovery across turns (Inferred)
• Broad interaction package: 7 hand traps, 7 negation-text, 13 removal-text cards (Inferred quality from card text)
• High-ATK boss options in the Extra Deck, such as GMX - COMPREX 3700 and Ultimate Conductor Tyranno 3500 (Verified stats)

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring run 3 times against a limit of 2 (Verified)
• No Side Deck, so no post-side plan (Verified)
• Low GMX purity: 34.5% exact-name, with 36 off-archetype copies across Dinosaur and generic cards (Verified)
• No recorded combos, so floor, median, and ceiling output cannot be measured (Verified gap)

Critical choke points

• Ash Blossom copy limit must be fixed before the deck can be scored as a legal list
• Extra Deck fusion routes depend on Dinosaur and GMX monsters being in hand or field, a potential single-point failure (Inferred)

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is run 3 times against a Semi-Limited limit of 2 (legality); Main 40 / Extra 15 / Side 0 composition; Card stats and banlist status for all listed cards; Archetype purity 34.5% exact-name; spread GMX 19, Jurrac 3, Evolzar 2, Evol 1, Kaiju 1; Boss ATK values from card data
• Inferred: Consistency estimates from hypergeometric probabilities (0.95 archetype core, 0.96 searcher group); Hand-trap and interaction quality read from card text; Going-first and going-second plans read from card text; Recovery route through searchers and Dinosaur recursion
• Provisional: Meta power (null; no dated metagame sample); Matchup and format fit (D13 held neutral)
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry: going-first/second, matchup, and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No guides for the GMX archetype No Side Deck, so post-side evaluation is absent
