Fossil Deck #769614 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Control
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion and Xyz boss monsters (Skull Convoy, Skull King, Skullgios, Plasma Magnum) summoned through Fossil Fusion and Rock-monster GY fuel; Magnet Warrior chain into Tellusion the Magna Warrior and Full Armored Utopic Ray Lancer
• Turn 1 (going first): Open a Magnet searcher (Beta, Magnet Bonding) or Weathering Soldier, convert to a Rock Level 4 body, then build toward a Fusion boss while holding Dark Hole, Typhoon or Cosmic Cyclone for the opponent's first board
• Turn 2 (going second): Use Dark Hole, Typhoon or Cosmic Cyclone to clear the opponent's first board, then rebuild with searchers and Fusion or Xyz bosses. Debunk and Sigma Minus cover monster effects and attacks
• Recovery: Weathering Soldier, Miracle Rupture, Gallant Granite and Mulcharmy Fuwalos recover resources from the GY and hand
• After siding: None: the deck runs 0 Side Deck cards, so there is no defined post-side plan

Why it scores here

The deck reliably opens a searcher-rich start: the searcher-text group (16 copies) has an 83% chance of at least one copy in a 5-card opening hand, and Beta, Magnet Bonding and Weathering Soldier each run 3 copies. Its conversion depends on Fossil Fusion, which has only 2 copies (about 18% to appear in an opening hand), so the Fossil line is fragile on its own. Recovery through the GY and Xyz and Fusion bosses with attack-ATK effects gives pressure in the midgame, and 12 spell/trap and monster interaction cards (Dark Hole, Typhoon, Cosmic Cyclone, Debunk, Sigma Minus, Tornado Dragon) add real interaction density. The main deck also carries roughly 10 dead or situational cards (Winged Dragon Sphere x3, Santa Claws x2, Hey Trunade, Book of Eclipse), the archetype core is almost absent from the list, and the deck has no Side Deck, so it does not earn points for post-side adaptability. No combo boards were recorded, so the floor, median and ceiling are inferred from card text rather than measured, and the score is built on the system, not an average of individual card scores. Archetype popularity and usage did not add points.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Control secondary for interaction; D13 dropped for the meta-neutral structural score and weights renormalised to 95. Structural ≈ 56, Going First ≈ 60, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: engine_conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null): 0.80*56 + 0.20*45 - 2 = 52

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.18 · 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 package (16 searcher-text copies, 83% to see one in a 5-card hand)
• Broad removal and negation spread across spells, traps and monsters
• High-ATK Fusion and Xyz bosses with ATK-reduction and double-attack effects

Weaknesses

• Fossil Fusion, the key Fossil starter, has only 2 copies (about 18% to appear in an opening hand)
• Roughly 10 dead or situational main-deck cards, including 3 Winged Dragon Sphere that cannot be Special Summoned
• No Side Deck, so no post-side plan or matchup tuning
• Off-archetype spread (18.6% exact-name purity) and missing core cards (1 of 25 usage-core cards present)

Critical choke points

• Fossil Fusion (2 copies) for the Fossil boss line
• Rock-monster GY fuel for Fusion summons
• Tributing or banishing Magnet Warriors for the Tellusion and Linear Magnum route

Recommended changes

Evidence & confidence

• Verified: Legal in OCG: 55 Main, 15 Extra, 0 Side; Daigusto Emeral Limited at 1 copy; Copy histogram: 11 triple, 6 double and 10 single Main cards; Archetype purity 18.6%; usage core 1 of 25 present
• Observed: No recorded combo boards exist for this deck
• Inferred: P(Fossil Fusion in 5-card hand) = 0.175 and P(searcher in 5-card hand) = 0.835, hypergeometric; Dead or situational card count of about 10 from card text; Interaction density from role hints and negation text
• Provisional: Matchup and format fit (D13) is unknown without a dated meta sample
• 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, brick rate) No Side Deck: post-side performance is unknowable Meta Power is Provisional unless a dated metagame sample is supplied
