Shark Deck #760053 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 30 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Xyz bosses from the Extra Deck, such as Number C107: Neo Galaxy-Eyes Tachyon Dragon (4500 ATK per evidence) and Number C32: Shark Drake LeVeiss (3100 ATK), built on Level 4 and Level 5 WATER materials from Shark monsters; Shark Drake and Number Xyz recursion through Drake Shark, Number 32, and Stealth Kragen Spawn
• Turn 1 (going first): Open with a Level 4 or 5 WATER monster (Buzzsaw Shark, Surfacing Big Jaws, Abyss Shark, or Effect Veiler) and build toward a Xyz Summon, keeping Ash Blossom and Effect Veiler up for the opponent's first interruption
• Turn 2 (going second): Use Effect Veiler, Ash Blossom, Infinite Impermanence, or Forbidden Droplet to answer the opponent's board, then Xyz Summon from the remaining monsters
• Recovery: Recover monsters from the GY with Armored Xyz, Full-Armored Xyz, and Surfacing Big Jaws, and rebuild through Xyz Armor Fortress or Number Xyz materials
• After siding: No side deck is registered (side_count 0), so there is no post-side plan to evaluate

Why it scores here

This list is Illegal in OCG: the Extra Deck holds 30 cards against a 15-card cap, and three cards exceed their copy limits (Seventh Tachyon at 3 against 1, Ash Blossom at 3 against 2, and a Forbidden Called by the Grave). The structural read is that the deck opens on WATER Level 4 and 5 monsters (Buzzsaw Shark, Surfacing Big Jaws, Abyss Shark, Effect Veiler, each about 34% to appear in an opening 5-card hand) and converts them into Xyz bosses, with nine hand traps giving it an 81% chance of at least one going second. The main weaknesses are the spread of the Extra Deck across 29 distinct Xyz cards, the 16 Level 0 spells and traps, and the absence of a side deck, which together make the lines brick-prone and hard to repeat. Recorded combos, usage-based win data, tournament results and guides are all absent, so the combo floor, median and ceiling are not measured and nothing in this read rests on them. Popularity and archetype-core usage (96% of hands contain at least one core card) confirm the list is real, but they did not add points, and card scores were not averaged into the deck score. Because the list is Illegal, the Final Contextual score is capped at 20 and this evaluation is theoretical and structural only.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Control secondary (not separately weighted; illegal-list structural read only). Structural ≈ 43, Going First ≈ 42, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-6); dependence on Extra Deck breadth / unfocused Extra (-4). Final formula: Structural 43 → 0.80*43 + 0.20*30 + modifiers (-10) ≈ 30.4, then capped to 20 because the list is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Nine hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence) give strong going-second interaction
• Several WATER Level 4 and 5 starters, each at 3 copies, make the opening engine reasonably accessible
• Strong Xyz boss options in the Extra Deck, such as Number C107 and Number C32

Weaknesses

• Illegal in OCG: Extra Deck size and three copy-limit breaches
• Extra Deck spreads across 29 distinct Xyz with no shared engine
• 16 Level 0 spells and traps in a 40-card Main increase brick risk
• No side deck, so no post-side adjustment is possible

Critical choke points

• Dependence on WATER Level 4/5 monsters to make the first Xyz Summon
• Legality: the Extra Deck must drop to 15 cards before the list can be evaluated normally

Recommended changes

Evidence & confidence

• Verified: Illegal status: Extra 30 against a 15-card cap and three copy-limit violations (Seventh Tachyon, Ash Blossom, Called by the Grave); Banlist statuses: Called by the Grave Forbidden, Seventh Tachyon Limited, Ash Blossom Semi-Limited, Foolish Burial Limited; Composition: 40 Main (21 distinct), 30 Extra (29 distinct), 0 Side, archetype exact-name purity 2.9%; Archetype core usage: Surfacing Big Jaws 90%, Buzzsaw Shark 70%, Abyss Shark 50%, Full-Armored Xyz 80%
• Inferred: Per-card starter access ≈ 0.34 in opening 5 (hypergeometric); Going-second hand-trap coverage ≈ 0.81; Brick and dead-hand risk from 13 non-monster cards and 16 Level 0 cards; Structural dimension scores and the 43 structural read; Interaction quality from negation and hand-trap text
• Provisional: Meta Power (null) and Matchup Coverage (D13) lack a dated metagame sample; Side deck adaptability (D12) cannot be assessed with 0 side cards
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck registered (side_count 0), so no post-side plan is evaluable deck title is null; no guides attached
