GMX Deck #772935 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 55 / 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 Jurrac/Evolzar Extra Deck threats, backed by Ultimate Conductor Tyranno and Dogoran as bosses. Text-only read; no combo boards recorded.; Synchro and Xyz boards (Jurrac Meteor, Jurrac Astero, Evolzar Dolkka, Evolzar Laggia) used as interaction-heavy follow-up.
• Turn 1 (going first): Fossil Dig or GMX Researcher Selande to find a Dinosaur or GMX Fusion engine piece, then Fusion Summon a GMX Fusion Monster. Hand traps are held for the opponent's turn.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Infinite Impermanence, Evenly Matched, Droll and Solemn Judgment to interrupt the opponent's first board, then rebuild through Dino searchers.
• Recovery: Returned Dino Daneen, Jurrac Megalo and Mulcharmy recursion plus Forbidden Droplet and Prohibition-style resets rebuild the board from GY and hand.
• After siding: Not evaluable. The deck has no side deck (side_count 0), so there is no post-side plan.

Why it scores here

The deck is illegal as submitted: three copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of two, so the structural score is shown for reference only and the final score is capped at 20. Structurally the core GMX engine is reliably reachable, with a 0.91 estimate of at least one archetype-core card in a 5-card opening hand (Inferred), but only 20 of 55 main-deck slots are GMX-named and 56 copies are off-archetype, which weakens engine coherence. Interaction is the deck's strongest area: 16 hand traps and 14 negation-text cards give high layering against going-second boards, and the Extra Deck covers Fusion, Synchro, Xyz and Link threats. No recorded combo boards, tournament link or side deck exist, so the conversion, floor, meta and side-deck scores rest on text inference and are low-confidence. The score reflects the deck as a system; it does not come from averaging individual card strength or from GMX's archetype popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 44, Going First ≈ 42, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violation (cap) (-15); Banlist exposure (-4); No side deck (-3). Final formula: Illegal legality cap applied: structural 44 and tournament reliability 35 give 0.80*44 + 0.20*35 = 42.2 before modifiers; modifiers total -7 gives 35; the illegal-deck cap then sets the final score to 20 (theoretical/structural only). Meta Power provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core GMX engine is reliably accessible in the opening hand (about 0.91).
• Dense hand-trap and negation suite (16 hand traps, 14 negation-text cards) gives strong going-second interaction.
• Full Extra Deck covering four summon types with high-ATK Fusion threats.
• Multiple searchers and GY recursion give card flow.

Weaknesses

• Illegal as submitted: three Ash Blossoms against a limit of two.
• Low archetype purity (20%) with 56 off-archetype copies weakens engine coherence.
• No side deck, so there is no post-side adaptation.
• No combo boards, tournament data or win-rate telemetry to verify conversion.

Critical choke points

• Dependence on a small set of Limited single copies (Foolish Burial, Solemn Judgment, Harpie's Feather Duster) that cannot be doubled.
• The Fusion engine runs through GMX cards, so losing the few GMX enablers stalls the Extra Deck plan.

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring runs 3 copies against a Semi-Limited limit of 2 (Illegal).; Main deck is 55 cards (legal range 40–60); Extra Deck is 15 cards (legal range 0–15); side deck is 0.; Seven Limited cards each run exactly one legal copy.; The archetype-core group is 20 copies with an opening-hand probability of 0.9067.
• Observed: Usage statistics show Fossil Dig, GMX Suppression Squad and Souleating Oviraptor are core to the GMX archetype (inclusion 73–93%).
• Inferred: Midrange with a Toolbox secondary, based on the mix of Fusion/Synchro/Xyz threats and 16 hand traps.; Engine coherence is weak (20% purity) and brick risk is moderate (about 9% no-core-card hand).; Going-second interaction is strong from hand-trap and negation density.
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link exists.
• 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 exists in YGOVN for going-first, going-second, matchup or brick rates. Meta Power is provisional unless a dated metagame sample is supplied. No side deck, so D12 cannot be measured from data.
