Fossil Deck #758308 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Pressure from Fur Hire Link/Xyz bosses and high-ATK K9 Xyz/Extra Deck monsters (K9-X Werewolf, Vallon, Nibiru, Divine Arsenal ZEUS) once the Fur Hire searcher chain has put monsters on the field.; Hand-trap and negation-driven disruption (Ash Blossom, Droll, Kuriboh, Ghost Ogre) that protects the board while the Extra Deck threats come down.
• Turn 1 (going first): Open a searcher (Rex, Beat, Fossil Dig, Filo, K9-66a Jokul), chain Fur Hire Normal/Special Summons into a Link or Xyz boss, and hold Ash Blossom or Droll for the opponent's first activation.
• Turn 2 (going second): Respond to the opponent's first Normal Summon or search with hand traps (Ash Blossom, Ghost Ogre, Kuriboh, Nibiru), then rebuild board through Fur Hire recursion.
• Recovery: Fur Hire monsters in the GY can be revived by Mayhem, Rookie, and Filo, and Rex/Beat can add or summon other Fur Hire monsters from the Deck.
• After siding: No side deck is registered, so there is no post-side plan. Best-of-3 play has no adaptation.

Why it scores here

The score is capped because the list is illegal: five copy-limit or Forbidden violations, including three copies of two Semi-Limited cards and two Forbidden cards. The structural read is built on the system, not on card averages. The Fur Hire searcher chain (19 searcher-text cards, P(at least one searcher in a 5-card opening hand) ≈ 0.89) gives a reasonable chance of going live, and the Extra Deck supplies high-ATK closing threats. Hand-trap density (9 cards, P(at least one in a 6-card hand going second) ≈ 0.68) and 7 negation effects add interaction. Against that, the deck has no combo records, no side deck, and an archetype label (Fossil) that matches none of its core engines: exact-name purity is 0%, and none of the 25 usage-core cards are present. The engines are split across Fur Hire, K9, Mulcharmy, and Kuriboh, which weakens consistency. Popularity and archetype label did not earn points, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 53, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); engine_conflicts (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*53 + 0.20*45 ≈ 51; context modifiers -12 → ≈ 39; the Illegal status caps the result at 25 (theoretical/structural-only).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · 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 searcher chain (19 searcher-text cards) gives high odds of a live engine on the first turn.
• High-ATK Extra Deck closers (K9-X Werewolf, ZEUS, Nibiru, Vallon) give strong board-ending pressure.
• Hand traps and negations (9 and 7) give layered interaction for going second.

Weaknesses

• Illegal as built: 5 copy-limit or Forbidden violations.
• No side deck, so best-of-3 has no adaptation.
• Fragmented engines with an archetype label that does not match the cards (Fossil, purity 0%).
• No recorded combos, so the floor and median are text-only inferences.

Critical choke points

• Forbidden Called by the Grave and Triple Tactics Talent must be removed before the list is playable.
• Ash Blossom and K9-17 Izuna at 3 copies must be cut to 2; Droll must be cut to 1.

Recommended changes

Evidence & confidence

• Verified: Legality: 5 violations (3 over-limit Semi-Limited/Limited/Forbidden combinations and 2 Forbidden cards); Main 55 and Extra 15 are within OCG size rules; Side 0 is legal.; Archetype purity 0%; 0 of 25 usage-core cards present; no tournament link.
• Inferred: Opening-hand odds: searcher group P(≥1 in 5) ≈ 0.89; hand-trap group P(≥1 in 6 going second) ≈ 0.68.; Interaction density and engine layering from card text and role tags.
• Provisional: Meta power and format fit: no dated metagame sample.
• Data gaps: No combos supplied: 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 for going-first/second, matchup, or brick rates. Meta Power is provisional without a dated metagame sample. No side deck registered, so post-side evaluation is absent.
