Shark Deck #772035 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• 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 pressure from the Shark / Number / Full Armored Xyz extra-deck options, with Surfacing Big Jaws and Veiss Shark putting monsters into Xyz material; Virtue Stream and LeVirtue Dragon board-control and recursion lines, plus Seventh Ascension and Seventh Tachyon as searchers for Number-type Xyz
• Turn 1 (going first): Open a Water starter (Surfacing Big Jaws, Veiss Shark, Buzzsaw Shark, Abyss Shark, Mulcharmy Purulia) and convert it into a Level 4 Xyz base, backed by hand traps (Ash Blossom, Infinite Impermanence, Droll and Lock Bird)
• Turn 2 (going second): Use Ash Blossom, Maxx C, Droll and Lock Bird, Dominus Impulse and K9-17 Izuna to interrupt the opponent's board, then rebuild a Xyz through Mulcharmy Purulia and Seventh Ascension
• Recovery: Recover through Seventh Ascension and Abyss Shark searches, plus Reincarnation Unveiling Mail and Full-Armored Xyz to stay in the field after a disruption
• After siding: Not evaluable: the side deck is empty (side_count 0), so there is no post-side plan

Why it scores here

The deck's Water-Xyz system opens reliably: the archetype core group gives about 98% odds of at least one core card in a 5-card opening hand, and the 3-copy Shark starters make a Level 4 Xyz base likely by turn 2. Its interaction density is respectable, with about 6 hand traps, 13 negation-text cards and 15 removal-text cards, so it can contest the opponent's first board. The score is not an average of card scores: it reflects the system's consistency and interaction on the whole list. It does not reflect the archetype being popular, since no meta share was supplied. The deck is illegal because it runs Bahamut Shark, which is Forbidden in OCG, so the score is capped at a theoretical, structural-only value. It has no side deck, which pulls down adaptability and post-side planning, and no recorded boards, so the combo floor and ceiling are text-only inferences.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary, not a formal ratio. Structural ≈ 56, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: banlist_exposure (-12); illegal_list_cap (-19). Final formula: No reliable metagame: 0.80*Structural(56) + 0.20*TournamentReliability(55) = 55.8, then banlist exposure -12 modifier gives 43.8, then the illegal-list cap applies, which sets the score to 25

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core Water-Xyz engine is redundant across 3-copy starters
• Hand trap and negation density (6 hand traps, 13 negation-text cards) is high
• Extra Deck covers several Xyz lines with a Level 4 Water access path

Weaknesses

• Illegal list: Bahamut Shark is Forbidden in OCG and run 1 copy
• No side deck, so no post-side plan
• No recorded combos, so the floor and ceiling are unknown
• Low exact archetype purity: only about 11% of cards carry the Shark name

Critical choke points

• Xyz summoning depends on Level 4 Water starters, so losing the early starter ends the Xyz plan
• Removing Bahamut Shark is required before the list is legal

Recommended changes

Evidence & confidence

• Verified: Main deck 40, Extra 15, side 0; Main and Extra sizes are legal; Bahamut Shark (Forbidden, run 1, legal copies 0) is the only violation; Copy limits for all other restricted cards are met (Limited 1, Semi-Limited 2); Archetype core group opens at about 0.98 for at least one card in 5
• Inferred: Starter reliability and brick rate from hypergeometric odds and card text; Interaction density from role hints and negation/removal text; Going-first and going-second plans from card text
• Provisional: Meta power and matchup fit (no dated meta sample supplied)
• 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 Meta Power is provisional unless a dated metagame sample is supplied Side deck is empty, so post-side behaviour cannot be scored
