Shark Deck #770940 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 27/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Water Xyz/Synchro boards (Shark Drake, Number 32, Stealth Kragen, White Aura Whale) built through Umi and Fish-based searches; Direct attacks and piercing from Mega Fortress Whale and Umi-enabled Water monsters
• Turn 1 (going first): Open a Fish/Umi starter (Fish Sonar, Kairyu-Shin, Surfacing Big Jaws, Abyss Shark) and search a second Water body; Ash Blossom and Infinite Impermanence protect the turn if the list were legal
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre & Snow Rabbit and Solemn-type hand traps to answer the first summon, then rebuild through Xyz material
• Recovery: Recur through Seventh Tachyon and Fishborg Harpooner, and rebuild Water Xyz from the GY
• After siding: No Side Deck: post-side adaptation is not possible in this list

Why it scores here

This OCG Shark list is Illegal: Seventh Tachyon is run at 3 copies against a limit of 1, and Ash Blossom and Super Polymerization are each run at 3 against a limit of 2. Those violations cap the result, so this is a theoretical, structural-only read and not a normal contextual score. Structurally the deck has real interaction density (9 hand traps and 14 negation-text cards) and a mixed Xyz/Synchro Extra Deck that gives it several boards to aim for. Consistency is weak: only 1.4% of the main deck is the exact Shark archetype name, 27 cards are generic, the copy histogram is spread across 29 distinct main cards, and the 0-Level spells and traps add dead-draw risk. No combo boards were recorded, so the ceiling and median scores are text-only inference, and the score did not come from Shark's popularity or from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 40, Going First ≈ 40, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal copy-limit violations (-12). Final formula: 0.80*Structural(40) + 0.20*TournamentReliability(35) = 39, then Illegal-list modifier -12 = 27 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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 hand-trap and negation coverage (9 hand traps, 14 negation-text cards)
• Searcher density (20 searcher-text cards) gives high starter access
• Mixed Xyz/Synchro Extra Deck offers several board options

Weaknesses

• Illegal in OCG: three cards over the copy limit
• Low archetype purity (1.4% exact Shark name) and wide sub-archetype spread
• No Side Deck
• Many generic and 0-Level cards that can be dead draws

Critical choke points

• Water Xyz/Synchro lines depend on Fish/Umi starters and the Number Xyz route
• Single-copy Solemn Judgment and Harpie's Feather Duster are the only answers to some boards

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 (within OCG size rules); Three copy-limit violations: Seventh Tachyon, Ash Blossom & Joyous Spring, Super Polymerization; Archetype exact-name purity 1.4% and 27 generic cards; Usage stats: 26 rows; 6 of 23 core cards present (26.1%)
• Inferred: Starter access P(>=1 searcher in 5) ≈ 0.91 from hypergeometric draw; Interaction density from hand-trap and negation text; Water Xyz/Synchro route viability from card text; Midrange primary strategy from composition and text roles
• Provisional: Meta Power is null; no dated metagame sample; D13 matchup and format fit based only on archetype presence
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown No Side Deck supplied Meta Power is Provisional unless a dated metagame sample is supplied
