Fossil Deck #548975 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Stun
• Format: ocg

Legality

Main 53 / Extra 17 / Side 0 — status: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Fusion or Synchro boss (Fossil Dragon Skullgios, Fossil Warrior Skull King, Adamancipator Risen) summoned through Fossil Fusion and the Fossil Rock-monster GY material loop; Adamancipator Risen Synchro boards built from excavation, with Gaia Plate and Nibiru as occasional beatsticks
• Turn 1 (going first): Open Fossil Fusion or Adamancipator Researcher / Friends, excavate or search a Rock monster, then Fusion or Synchro summon a Fossil boss. Only about 26% of 5-card hands contain at least one Fossil Fusion (Inferred).
• Turn 2 (going second): Use Effect Veiler, Ash Blossom, Evenly Matched and Nibiru as hand traps to stop the opponent's first board, then rebuild through Fossil recursion. Going-second hand-trap coverage is about 53% (Inferred).
• Recovery: Banish Fossil Fusion-linked Fusion monsters from the GY and use Weathering Soldier, Time Stream and Skull Bone effects to recover Fusion Spells and monsters (text-only read, Inferred).
• After siding: No side deck is registered, so there is no post-side plan. Best-of-3 play is not supported by this list.

Why it scores here

The list is illegal in OCG: six Forbidden cards are run, Super Polymerization is over its Semi-Limited limit, and the Extra Deck holds 17 cards against a limit of 15, so the score is capped and the evaluation is theoretical and structural only. Within that cap, the system reliably reaches a Fossil Fusion line and a Fusion or Synchro boss, but only about 26% of going-first opening hands contain Fossil Fusion (Inferred), so consistency is weak. No recorded boards exist, so conversion (D3) and median output (D4) rest on card text alone and carry low confidence. Interaction is dense on paper (six hand traps, ten negation texts, eleven removal texts) but several of those pieces are the illegal cards. The deck has no side deck. Popularity and archetype usage did not add points: the usage statistics list mostly cards this deck does not run, and the score was built from the system as a whole, not by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 42, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist_exposure (-10); extra_deck_size_violation (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); Illegal legality cap applied: score capped low and labelled 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

• Real Fusion and Synchro bosses with high ATK (Skullgios 3500, Skull King 2800, Risen Dragite 3000)
• Multiple engine entry points: Fossil Fusion, Adamancipator searchers, Weathering Soldier
• Dense negation and hand-trap text (Ash Blossom, Effect Veiler, Evenly Matched, Nibiru)

Weaknesses

• Illegal in OCG: six Forbidden cards, one Semi-Limited overage and a 17-card Extra Deck
• Only about 26% going-first access to Fossil Fusion, so the engine is inconsistent
• 28 Level-0 spell and trap slots and 19 tech cards dilute the engine
• No side deck and no combo evidence, so post-side and conversion claims are unverified

Critical choke points

• Fossil Fusion (3 copies) is the main starter; a single missing copy in hand collapses most lines
• The Rock-monster GY requirement for Fusion summons depends on the early trades going through

Recommended changes

Evidence & confidence

• Verified: Illegal status: six Forbidden cards, Semi-Limited overage on Super Polymerization, Extra Deck 17 > 15; Main Deck 53 and Extra Deck 17, side 0; Hypergeometric draw odds for 1, 2 and 3 copies
• Observed: Archetype purity 28.6% exact name; 20 Fossil copies, 16 Adamancipator copies
• Inferred: Consistency estimate from hypergeometric draw odds and searcher groups; Hand-trap coverage and brick estimate from text and composition
• Provisional: Meta Power and tournament reliability (no dated sample, no 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 usage_statistics core list (Magnet Warrior and related cards) does not match this Fossil list; core coverage unreliable no win-rate telemetry; going-first, going-second and matchup signals are Inferred Meta Power is provisional without a dated metagame sample deck title is null
