Fossil Deck #774121 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Synchro
• Format: tcg

Legality

Main 42 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro boss monsters from the Adamancipator Risen line (Risen - Tiamite 3300 ATK, Risen - Dragite 3000 ATK) plus off-theme Synchro bosses (Swordsoul Supreme Sovereign - Chengying, Snake-Eyes Vengeance Dragon, The Three Champions of Swordsoul).; Link and Xyz pressure from Adamancipator Luminous, Dogurad, and Gallant Granite; Gallant Granite can also add a Rock monster to hand.
• Turn 1 (going first): Turn 1: Normal or Special Summon an Adamancipator starter (Conductor, Seeker, or Researcher from hand). Main Phase: excavate the top 5 for a Level 4 or lower Rock monster, then Synchro or Link into a Risen boss.
• Turn 2 (going second): Hold hand traps (Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Effect Veiler, Nibiru) to answer the opponent's first summon chain, then go to a Synchro boss from the excavated Rock monsters.
• Recovery: Searchers and recursion: Adamancipator Mates and Half Slice of Nickeline search Deck monsters, Adamancipator Resonance and Sentry Soldier of Stone return from the GY, and Gallant Granite recovers a Rock monster.
• After siding: None. The deck runs zero side cards, so there is no post-side plan.

Why it scores here

The list is illegal as submitted: three copies of Ash Blossom & Joyous Spring against a limit of two. Under the rubric this is a theoretical, structural-only read with no normal Final score, so 35 is a capped value. The structural read uses the Midrange profile. The engine is the Adamancipator excavate loop: three-copy starters and 26 archetype-core cards give a high probability of an opening starter (about 0.99 for at least one core card in a 5-card hand), and the Synchro bosses have high ATK. Recursion and searchers help recovery, and ten hand traps give going-second interaction. Points were not earned from popularity or meta-share, and no card scores were averaged. The deck is weaker on structure than on engine: it runs no side deck, and its Fossil label has a 1.8% exact-name purity, with its body built from Adamancipator, Koa'ki Meiru, Swordsoul, and -Eyes cards. Combo evidence is absent, so floor, median, and ceiling are text-only inferences.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: Banlist exposure (-8); Engine conflicts (-4). Final formula: Uncapped: 0.80*59 + 0.20*55 + modifiers (-12) = 46. Illegal-deck cap applied: score = 35 (theoretical / structural-only; no normal Final Contextual score). Meta Power is provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · 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 Adamancipator starter and searcher package (11 searchers, 8 starter types)
• Ten hand traps and tech cards for going-second interaction
• High closing power from Risen - Tiamite and three 3000-ATK Synchro bosses

Weaknesses

• Illegal as submitted: Ash Blossom at 3 copies, limit 2
• No side deck, so there is no post-side adaptability
• Mixed engines: Koa'ki Meiru and Swordsoul/-Eyes cards are off-theme for the Fossil label
• Koa'ki Meiru cards need Iron Core of Koa'ki Meiru, which the list does not run

Critical choke points

• Ash Blossom at 3 copies is illegal and would be cut to 2 in any legal build
• The Adamancipator excavate loop needs Rock monsters at Level 4 or lower in the Deck
• Synchro summons need a Tuner in hand or field, so Tuner count matters

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom & Joyous Spring at 3 copies against a limit of 2 (Semi-Limited); Main 42, Extra 15, Side 0 are within the TCG size rules; Droll & Lock Bird (Limited, 1 copy) is legal; Extra Deck composition: 4 Link, 10 Synchro, 1 Xyz (listed as 15 slots); Archetype purity: 1.8% exact-name; 29 Adamancipator copies, 5 Koa'ki Meiru, 2 Swordsoul, 1 -Eyes Dragon
• Inferred: Starter access: 0.32 per 3-copy starter in hand5; core group 0.99; Interaction density: ten hand traps and tech cards, with 0.83 going-second hand-trap probability; Koa'ki Meiru cards have no Iron Core target in the list; Scores for D1-D14 and the Midrange structural read
• Provisional: Meta Power (null, no dated metagame sample); D13 matchup and format fit (no tournament link)
• Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inferences No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry exists in YGOVN; all consistency numbers are Inferred Meta Power is Provisional without a dated metagame sample No side deck (0 cards), so post-side plan and D12 cannot be measured Usage statistics conflict with the card list: missing_core and in_this_deck flags mark Three Champions of Swordsoul, Chengying, and Snake-Eyes Vengeance Dragon as absent, but the cards array has them at 1 copy each, and the other 10 'missing' cards are also present. core_present_pct 60 is unreliable and was not used Deck title is null, so the deck name is unavailable
