Shark Deck #770081 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Xyz engine
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Xyz boss attacks (Number C32: Shark Drake LeVeiss, Number 32: Shark Drake, Number 101 / N.As.H. Knight line) built off Shark starters; Stealth Kragen and Full Armored Crystalzero Lancer boards that grind the opponent's monsters down
• Turn 1 (going first): Normal Summon Veiss Shark or Buzzsaw Shark, chain into a Level 4 WATER Xyz, and use Surfacing Big Jaws or Drake Shark for extra bodies (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence and Dominus Impulse for the opponent's first search or Special Summon, then rebuild the Shark board (Inferred)
• Recovery: Seventh Ascension and Seventh Tachyon search the Deck for Shark or Barian-type spells, and Full-Armored Xyz or Armored Xyz recover Xyz monsters from the Graveyard (Inferred)
• After siding: None: the deck runs no Side Deck, so there is no post-side plan (Verified)

Why it scores here

The deck is scored as a system: its Shark starters (three copies each of Veiss Shark, Buzzsaw Shark and Surfacing Big Jaws) reach a live Level 4 WATER Xyz engine often enough, with about a one-in-three chance of at least one of those three-copy starters in a going-first opening hand. Its interaction suite (Ash Blossom, Infinite Impermanence, Dominus Impulse, Virtue Stream and the Xyz negate effects) is the strongest part of the list, which is why interaction and going-second scores sit above the engine scores. The list is Illegal: Seventh Tachyon, Ash Blossom and Dominus Impulse are each run three times against limits of one or two, so the score is capped at 35 instead of the normal contextual result. Popularity did not earn points, and the card scores were not averaged; the deck has no Side Deck and no combo logs, so the post-side and combo-ceiling reads stay Inferred or Provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-10); no side deck (-2); Illegal cap (-7). Final formula: No reliable metagame: 0.80*Structural(55.9) + 0.20*TournamentReliability(45) = 53.7; modifiers -12 gives 41.7; Illegal cap applied, final 35

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (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 negate suite (Ash Blossom, Infinite Impermanence, Dominus Impulse, Virtue Stream)
• Shark starters are triple-copied, which gives a reasonable chance of a live engine on going first
• Strong Xyz boss options at the top of the Extra Deck

Weaknesses

• Illegal copy counts on three cards
• No Side Deck
• Low Shark exact-name purity, so the engine is spread across generic Xyz and Seventh cards
• Fusion slot is weakly supported by a single limited Instant Fusion

Critical choke points

• Level 4 WATER Xyz material is required for most lines, so losing the Shark starters early stalls the board
• Seventh Tachyon is a Limited card, so the legal build must cut it to one copy

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 counts from legality; Seventh Tachyon 3 copies vs limit 1; Ash Blossom 3 vs 2; Dominus Impulse 3 vs 2; No Side Deck; Probabilities computed from the resolved list
• Inferred: Shark starter access about 0.34 for a 3-copy starter in a going-first 5-card hand; Interaction is layered across hand traps and Xyz negates; Going-second strength from hand traps; Closing power from Number C32 and Number 32 text
• Provisional: Format fit and matchup coverage, since there is no tournament link or 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 match record absent No win-rate telemetry for going-first, going-second, matchup, brick or starter rates Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null
