Legality
Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Fossil Fusion into Fossil Fusion Monsters (Skullgios, Skull King, Skull Convoy) for large Extra Deck beaters, with Adamancipator Risen Synchros as a secondary attacker line; Adamancipator Risen - Tiamite and Adamancipator Risen - Raptite as Synchro beaters and disruption, if the Extra Deck summons are reachable
- Turn 1 (going first): Open a Rock or Adamancipator starter (Researcher, Seeker, Conductor, Analyzer), excavate for a Level 4 or lower Rock, and use Fossil Fusion or Specimen Inspection to reach a Fossil Fusion Monster
- Turn 2 (going second): Hold Ash Blossom, Evenly Matched, Nibiru and Doki Doki as hand traps to answer the opponent's first summon, then rebuild through Adamancipator searches and Fossil Fusion
- Recovery: Adamancipator Friends, Mates and Signs recover searchers, and Miracle Rupture and Time Stream recycle Fusion materials from the GY
- After siding: Side deck is empty (Side Deck size 0); no post-side plan exists in this list
Why it scores here
This list is Illegal in OCG: it runs 3 copies of Ash Blossom & Joyous Spring (limit 2), 1 copy of the Forbidden Geonator Transverser, and 17 Extra Deck cards (limit 15), so it receives a structural-only score capped low and not a normal contextual score. Its Structural value (45) reflects an engine that is reasonably accessible, since 9 Main Deck cards that search or excavate into Rock and Adamancipator monsters give a 0.74 chance of at least one searcher in a going-first hand. Its weakness is the Main Deck: only 16 of 53 cards are exact Fossil-named, the core (5 copies of Adamancipator Analyzer and the Fossil-named cards) is incomplete against the archetype's usage data (3 of 25 core cards present), and the side deck is empty. Popularity or archetype identity earned no points, and no card scores were averaged; no recorded combos exist, so the combo dimensions rest on text-only inference.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(at least 1 of 3 copies in a 5-card going-first hand) ≈ 0.26 per card; searcher group 0.74 in opening hand; 2-card bootstrap plausible but not measured (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | Copy histogram 12 singles / 7 doubles / 9 triples; 7 hand traps and multiple Rock searchers reduce dead hands but Spell-heavy main (24 Spells) and one-card Fossil Fusion dependence leave brick risk (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | No parseable combos; ceiling read from card text: Fossil Fusion into Skullgios or Skull Convoy with Time Stream recursion (Inferred) |
| D4 | Combo Floor & Median Output | 35 | No combo boards supplied, so median output cannot be measured; text suggests a single starter route with many dead early turns (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Two Synchro and several Link routes and recursion via Adamancipator Friends and Miracle Rupture give some alternatives after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 45 | Recursion via Fossil Warrior Skull Bone, Dragite and Time Stream plus multiple searchers; Fusion materials are spent quickly (Inferred) |
| D7 | End-Board & Interaction Quality | 45 | Four negation-text cards and 6 removal-text cards, with Ash Blossom and Evenly Matched as hand traps; overlimit Ash Blossom copies are illegal (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 40 | Going-second board breaking depends on Raltzer-style removal via Raigeki and Heat Wave; no going-second split available (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Fossil Fusion Monsters reach 2800 to 3500 ATK with piercing and multi-attack text; no end-board data (Verified text, Inferred output) |
| D10 | Main Deck Efficiency & Flexibility | 35 | 53 Main cards with 24 Spells and 3 Traps; 3 off-archetype Synchro and Link cards dilute cohesion; archetype exact purity 22.9% (Verified count, Inferred cohesion) |
| D11 | Extra Deck Efficiency & Coverage | 50 | 17 Extra Deck cards across Fusion, Synchro, Xyz and Link; limit is 15, so 2 cards must be cut; Fossil and Adamancipator coverage is good (Verified count) |
| D12 | Side Deck Adaptability | 20 | Side Deck is empty (0 cards); no post-side adaptability exists in this list (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link or dated meta sample; archetype meta-share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step Fusion lines with Extra Deck material requirements and many Spell timings demand high pilot skill (Inferred) |
How the score was computed
Strategy profile: Combo primary; Toolbox secondary noted but not blended numerically. Structural ≈ 45, Going First ≈ 45, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); illegal status cap (-6). Final formula: 0.80*Structural(45) + 0.20*TournamentReliability(40) = 44, plus modifiers (-12) = 32; Meta Provisional; Illegal status, so theoretical/structural-only
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.26 · 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
- Searcher density: 12 searcher-text cards give a 0.74 chance of at least one searcher in a going-first opening hand
- Multiple Fossil Fusion Monsters with piercing, multi-attack or ATK-swap text give strong closing threats
- Hand traps (Ash Blossom, Evenly Matched, Nibiru, Doki Doki) give going-second interaction
Weaknesses
- Illegal in OCG on three separate counts (Ash Blossom over limit, Geonator Transverser Forbidden, Extra Deck 17 of 15)
- Only 22.9% exact-name Fossil purity; 24 generic cards and 24 Adamancipator cards dilute the Fossil core
- Fossil Fusion (2 copies) is the single Spell that gates every Fossil Fusion Monster, a choke point
- Empty Side Deck gives no post-side adaptability
Critical choke points
- Fossil Fusion is required for every Fossil Fusion Monster, and only 2 copies are run
- Ash Blossom at 3 copies is illegal; removing one copy is required before the deck is playable
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | one copy of Ash Blossom & Joyous Spring | a legal card (e.g., one Adamancipator or Fossil searcher) | Ash Blossom at 3 copies exceeds the OCG Semi-Limited limit of 2 |
| 2 | Geonator Transverser | a legal Link-2 or Extra Deck replacement | Geonator Transverser is Forbidden in OCG |
| 3 | 2 Extra Deck cards (lowest-impact Synchro/Link cards) | none | Extra Deck must be 15 or fewer |
| 4 | a Side Deck slot count of 0 | a 15-card Side Deck with Fossil and Adamancipator answers | Empty side deck gives no post-side plan |
Evidence & confidence
- Verified: OCG copy-limit violations (Ash Blossom 3 vs 2; Geonator Transverser Forbidden); Extra Deck count 17 exceeds limit 15; Exact-name Fossil purity 22.9% (16 of 70 copies); Usage data: 3 of 25 core cards present
- Inferred: Going-first searcher access 0.74 from hypergeometric estimate; Brick rate and consistency read from copy histogram and Spell-heavy composition; Interaction density from text-only role tags
- Provisional: Meta Power and matchup fit (no dated meta sample or tournament link)
- 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, going-second and matchup results unknown Meta Power is Provisional without a dated metagame sample Side Deck is empty; post-side adaptability cannot be assessed
