Shark Deck #772037 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Xyz boss beats from the Extra Deck (Number C32: Shark Drake LeVeiss 3100 ATK, Number 32: Shark Drake 2800 ATK, Number C32: Shark Drake Veiss 2800 ATK); Full-Armored Xyz / Xyz Armor Fortress armored boards plus Virtue Stream removal
• Turn 1 (going first): Open Veiss Shark / Buzzsaw Shark / Surfacing Big Jaws, summon into a Level 4 WATER Xyz, and extend with Mulcharmy Purulia draws
• Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Maxx C, Infinite Impermanence and Dominus Impulse to slow the opponent's summons, then rebuild a board through Xyz
• Recovery: Seventh Ascension recursion, Mulcharmy Purulia draw triggers, and Xyz materials carried over into a new Xyz
• After siding: None: the deck runs no Side Deck (Side Deck size 0), so there is no post-side plan

Why it scores here

The deck's scored system is a Xyz-centric Shark shell that reliably gets a Level 4 WATER starter live through Veiss Shark, Buzzsaw Shark and Surfacing Big Jaws, with about a 34% chance per 3-copy starter in a 5-card opening hand. Its interaction suite (two Ash Blossom, Droll & Lock Bird, Maxx C, Infinite Impermanence, Dominus Impulse, K9-17 Izuna and Xyz-side negations) gives it real going-second resilience. The score is held down by the illegal list: Bahamut Shark is Forbidden in OCG and is run as a single copy, so the deck is capped as structural-only. Low archetype purity (10.9% exact name; 49 off-archetype copies across Number, Seventh, K9, Mulcharmy, Dominus and generic Xyz pieces), 23 distinct main-deck cards with 12 singletons, no side deck, and no recorded boards mean the floor and median are unmeasured. Popularity of the Shark archetype was not counted toward the score, and no card scores were averaged into it.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no secondary weighting applied. Structural ≈ 50, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Banlist exposure (illegal list) (-10); No side deck (-2); Illegal cap (-6). Final formula: No reliable metagame: 0.80*Structural(50) + 0.20*TournamentReliability(42) = 48.4, then context modifiers (-12) = 36.4, then Illegal cap applied = 30 (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

• Layered interaction: 6 hand traps, 13 negation-text and 15 removal-text cards
• Several independent Level 4 starters (Veiss, Buzzsaw, Big Jaws, Abyss Shark, Mulcharmy Purulia)
• Strong going-second hand-trap coverage (P(>=1) 0.65 in a 6-card hand)
• High-ATK Xyz boss options (LeVeiss 3100, Shark Drake 2800)

Weaknesses

• Illegal as submitted: Bahamut Shark is Forbidden
• Low archetype purity (10.9% exact name) with Number, Seventh, K9, Mulcharmy and Dominus pieces mixed in
• No side deck
• No combo boards, so floor, median and ceiling are unmeasured
• Xyz-heavy chains add decision load and error risk

Critical choke points

• Level 4 WATER Xyz materials: the Xyz line depends on a small set of Level 4 starters
• Bahamut Shark slot must be removed before any legal evaluation holds

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 sizes; Bahamut Shark Forbidden with 1 copy run (over limit); Card text for all listed cards; Archetype purity 10.9% and off-archetype count 49; Usage stat: Surfacing Big Jaws, Crystal Shark and Seventh Ascension at 71-86% inclusion
• Inferred: Starter consistency from hypergeometric estimates; Hand-trap and removal coverage quality from text; Going-first and going-second estimates; Brick and dead-draw risk from copy histogram and composition
• Provisional: Meta power and matchup fit (no dated meta sample or tournament link)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for going-first, going-second, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
