Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

Win condition: Fusion Summon GMX / Dinosaur boss monsters (GMX - COMPREX, GMX - ALLOS, GMX - VELOX, Evolved Daneen) from the Extra Deck using GMX and Dinosaur materials, with GMX Applied Experiment #55 and GMX 55th Experiment Report as the fusion engines.; Link and Xyz pressure (Promethean Princess, Amphibious Swarmship Amblowhale, Evolzar Dolkka) and Dinosaur board-breaking via Ultimate Conductor Tyranno.
Turn 1 (going first): Normal Summon GMX Researcher Selande to search a GMX Spell/Trap, then Applied Experiment / Partner Selandea into a GMX Fusion Monster; Ash Blossom and Droll & Lock Bird are held up as interaction.
Turn 2 (going second): Hold Ash Blossom, Maxx C, Droll & Lock Bird and Infinite Impermanence to disrupt the opponent's first summon or search, then rebuild with a Fusion Summon from the Extra Deck.
Recovery: Searchers (Returned Dino Daneen, Kaitoptera, Fossil Dig, Reinforcement of the Army) and graveyard recursion (Souleating Oviraptor, Mulcharmy Fuwalos, GMX Chairman Kimridge) re-fill the hand after a disruption.
After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan.

Why it scores here

This is an illegal list, so the score is a capped structural read only. The 21 GMX core copies and 17 searcher-text cards make the engine easy to reach (archetype-core P(>=1 in a 5-card hand) = 0.98, Inferred), which earns the high D1 and D4 starter-access reads. Interaction density is high (two Ash Blossom, Droll & Lock Bird, Maxx C, Harpie's Feather Duster, Crossout Designator, Infinite Impermanence), which earns D7. Points were not earned from popularity or meta-share, since no tournament data was supplied, and card scores were not averaged. The deck runs Miscellaneousaurus three times against a limit of one and Cross-Sheep, which is Forbidden, so the list cannot be played as built; the Final Contextual score is capped at 20 and the evaluation is theoretical only.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	75	P(>=1 GMX core in a 5-card hand) = 0.98 and P(>=1 searcher-text card) = 0.95; no combo data to confirm a live starter (Inferred)
D2	Opening-Hand Quality & Brick Management	60	17 searchers and 14 removal-text cards reduce brick risk, but 35 of 55 cards are off-archetype and several interaction cards compete for the same hand slots (Inferred)
D3	Combo Conversion & Ceiling	55	Fusion/Link/Xyz boss monsters at 3000-3700 ATK give a high ceiling from card text; no recorded boards, so this is a semantic read only (Inferred)
D4	Combo Floor & Median Output	45	No combos_evidence rows (0 boards), so the median output cannot be measured and is estimated from text alone (Inferred)
D5	Interruption Resilience & Route Redundancy	55	Two Ash Blossom plus Droll & Lock Bird give some interruption coverage, and Dino recursion gives some route redundancy; no measured resilience data (Inferred)
D6	Resource Economy, Recovery & Grind	50	Excavation effects cost 400 LP per card, and graveyard recursion refills resources, which roughly balances out (Inferred)
D7	End-Board & Interaction Quality	75	Two Ash Blossom, Droll & Lock Bird, Maxx C, Harpie's Feather Duster, Crossout Designator and Infinite Impermanence give broad interaction; the Extra-Deck negates are semantic reads (Inferred)
D8	Going-Second & Board-Breaking Power	60	Harpie's Feather Duster and Crossout Designator remove or negate board pieces, but there is no going-second combo split data (Inferred)
D9	Offensive Pressure & Closing Power	70	GMX - COMPREX (3700 ATK), GMX - ALLOS (3000) and Ultimate Conductor Tyranno (3500) give strong end-board pressure from card stats (Verified stats, Inferred plan)
D10	Main Deck Efficiency & Flexibility	45	40 main cards with 28 distinct names and 35 off-archetype copies; the GMX core is only 20 exact-name copies (36.4% purity) (Verified composition)
D11	Extra Deck Efficiency & Coverage	55	15 Extra Deck cards with 13 distinct names; Cross-Sheep is Forbidden and must be removed, leaving 14 usable Extra cards (Verified legality)
D12	Side Deck Adaptability	10	Side Deck is empty (0 cards), so there is no post-side adaptability to score (Verified composition)
D13	Matchup Coverage & Format Fit	50	No tournament link or archetype meta-share in the export, so format fit is provisional (Provisional)
D14	Pilotability & Error Tolerance	35	Multiple fusion chains, Ash Blossom timing and Link/Xyz branches add decision load and error risk (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal list cap (-38); No side deck (-2). Final formula: Illegal list: Structural (58, Combo profile) is shown for reference only; the final score is capped at 20 per the legality guardrail. Meta is provisional/null.

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.98 · 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 GMX core (21 copies) with a high starter-access probability
17 searchers plus graveyard recursion for hand refill
Broad interaction suite (two Ash Blossom, Droll & Lock Bird, Maxx C, Harpie's Feather Duster, Crossout Designator, Infinite Impermanence)
High-ATK fusion and link bosses in the Extra Deck

Weaknesses

Illegal as built: Miscellaneousaurus x3 (limit 1) and Forbidden Cross-Sheep
Low archetype purity (36.4% exact-name GMX copies)
No Side Deck
No recorded boards, so the combo floor and median are unmeasured

Critical choke points

Single Extra-Deck fusion route through GMX Applied Experiment #55 / GMX 55th Experiment Report
Forbidden Cross-Sheep occupies an Extra slot that must be removed before the list is legal

Recommended changes

Priority	Remove	Add	Reason
1	Cross-Sheep (50277355)	A legal Extra Deck fusion, link or Xyz monster that fits the GMX/Dinosaur plan	Forbidden in OCG; the list cannot be legally played with it.
2	2 copies of Miscellaneousaurus (38572779)	1 more GMX or Dinosaur monster, or a Dinosaur searcher	The OCG limit is 1; the deck runs 3, which is an over-limit violation.
3	Off-archetype filler (e.g. Hey, Space Trunade!, Double Evolution Pill)	A Side Deck of 5-15 cards	The Side Deck is empty (0 cards), so there is no post-side plan.

Evidence & confidence

Verified: Legality: Illegal, Cross-Sheep Forbidden, Miscellaneousaurus over limit; Main 40 / Extra 15 / Side 0 counts within size rules; Copy histogram and exact-name archetype purity (36.4%); Card stats and text for the GMX Extra Deck bosses
Inferred: D1 starter access (0.98 archetype-core probability); Interaction density and quality read from card text; Going-first and going-second plan estimates; Structural score 58 (Combo profile)
Provisional: Format fit and matchup coverage (no tournament data); Meta Power (null, no dated metagame sample)
Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Side Deck is empty Meta Power is provisional unless a dated metagame sample is supplied
