Identity & game plan

Win condition: No single engine: closure comes from whichever off-archetype line lands first (Flower Cardian Lightflare or Divine Scorpion Beast of Serket attacks, or Exosister Mikailis from the Extra Deck).; Adamancipator excavation into Rock Link/Synchro boards, plus Triangle O board-wipe if the three named monsters are all present.
Turn 1 (going first): Open a Rock starter (Adamancipator Seeker, Researcher, Analyzer, Cabrera Stone or Ashoka Pillar), reach a Synchro or Link with Doki Doki or Mahaama, and hold Ash Blossom or Droll as a hand-trap follow-up.
Turn 2 (going second): Use Ash Blossom, Maxx C and Droll & Lock Bird to slow the opponent's first Special Summon, then rebuild a board from Rock searchers and Extra Deck attackers.
Recovery: Recover through Adamancipator excavation and Rock searchers (Cabrera Stone, Ashoka Pillar, Adamancipator Signs), which return a Rock monster to the field or the top of the Deck.
After siding: No Side Deck is registered (Side Deck size 0), so there is no post-side plan; the deck cannot adapt between games.

Why it scores here

The deck is labelled Exosister, but only one card is an Exosister (Exosister Mikailis, in the Extra Deck, with exact-name purity 1.8%) and only 2 of the 21 core cards are present. The list is a pile of Rock-type families (Ancient Treasure, Adamancipator, Flower Cardian, Naturia, Marincess, Yummy), so the score rests on how the system works, not on the Exosister label or on individual card strength. Consistency is moderate: several Rock starters run at 3 copies, so P(at least one in a 5-card opening hand) is about 0.34 per card, but no single engine is reliably live on turn 1. Hand traps are the stronger part: Ash Blossom, Maxx C and Droll & Lock Bird give about a 0.49 chance of at least one in a 6-card going-second hand, and the Extra Deck gives strong closers. The deck has no Side Deck and no combo or tournament data, so the score is Structural-only with a Provisional meta, and it is penalised for engine conflicts and the missing side. Score is not an average of card scores, and popularity did not earn points.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	58	P(>=1 3-copy starter in 5-card hand) ≈ 0.34; several Rock starters give multiple bootstrap routes, but no single engine is reliably live (Inferred)
D2	Opening-Hand Quality & Brick Management	48	Spells such as Triangle O, Catapult Zone, Totem Pole and Adamancipator Signs are dead without their partners; 17 distinct main-deck cards with heavy 3-copy redundancy (Inferred)
D3	Combo Conversion & Ceiling	55	No parseable boards; the Triangle O board-wipe and Adamancipator excavation chain give a plausible ceiling from text only (Inferred)
D4	Combo Floor & Median Output	42	No combos supplied, so median output cannot be measured; off-archetype pieces lower the typical turn-2 board (Inferred)
D5	Interruption Resilience & Route Redundancy	50	Two hand-trap families and several Rock searchers give alternative lines after disruption; Ash Blossom and Droll add interaction (Inferred)
D6	Resource Economy, Recovery & Grind	52	Adamancipator excavation and Rock searchers provide some recursion and card flow, but no measured resource data (Inferred)
D7	End-Board & Interaction Quality	60	Ash Blossom, Maxx C, Droll, Totem Pole, Gorgon and Naturia negation text give layered interaction (Inferred semantic read)
D8	Going-Second & Board-Breaking Power	52	Hand-trap P(>=1 in 6 cards going second) ≈ 0.49; Flower Cardian Lightflare (5000 ATK) and Triangle O can break boards (Inferred)
D9	Offensive Pressure & Closing Power	60	Extra Deck attackers (Lightflare 5000 ATK, Scorpion 3000 ATK, Lightshower 3000 ATK) give high endboard ATK once set up (Verified stat, Inferred conversion)
D10	Main Deck Efficiency & Flexibility	50	40 main cards, 17 distinct, with 10 cards at 3 copies; the off-archetype spread lowers coherence, though compactness is adequate (Inferred)
D11	Extra Deck Efficiency & Coverage	45	15 Extra Deck cards spanning Xyz, Link, Fusion and Synchro with several unrelated families, so most slots serve different lines (Inferred)
D12	Side Deck Adaptability	10	Side deck is empty (Side Deck size 0); no post-side plan is possible (Verified)
D13	Matchup Coverage & Format Fit	45	No tournament link, no meta-share and no win-rate telemetry; the core-card deviation from usage stats is verified but matchup fit is Provisional
D14	Pilotability & Error Tolerance	40	Multiple engines with sequencing across Rock, Flower Cardian and Link lines are hard to play consistently (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 49, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Engine conflict (-4); No side deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*49 + 0.20*40 = 47.2, plus modifiers -7 = 40

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.34 · 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

Legal list at 40/15/0 with no copy-limit violations
Layered hand-trap and negation suite (Ash Blossom, Maxx C, Droll, Gorgon, Naturia)
Strong Extra Deck closers (Lightflare, Scorpion, Lightshower)

Weaknesses

No coherent engine: the Exosister label is not reflected in the card pool
No side deck
Heavy reliance on many different starter families, each needing specific partners

Critical choke points

Rock monster presence for Adamancipator, Cabrera Stone, Ashoka Pillar and Triangle O
Flower Cardian Synchro setup for the Lightflare payoff

Recommended changes

Priority	Remove	Add	Reason
1	Off-archetype Extra Deck slots (Marincess Aqua Argonaut, Yummy Snatchy, Magical Musketeer Max)	Core Exosister cards (Elis, Martha, Pax, Betrayal) to match the label, or commit to one Rock/Flower Cardian engine	Consolidating around one engine would cut engine conflict and lift D1, D2 and D11
2	None	A Side Deck of 5 to 10 cards aimed at the most common opposing engine	Would add a post-side plan and lift D12, which is currently 10

Evidence & confidence

Verified: Legality: 40 main, 15 extra, 0 side; all restricted cards within legal copy limits; Exact-name Exosister purity 1.8%; 2 of 21 usage-core cards present; Hypergeometric probabilities from the resolved list
Inferred: Consistency and brick estimates from composition and card text; Hand-trap and interaction read from card text; Going-first and going-second read from card text and probabilities
Provisional: Meta Power (no dated metagame sample); Matchup fit (D13), no tournament data
Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are 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 Deck title is null, so the archetype label is taken from the archetype field alone
