Shark Deck #771445 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Tempo
• Format: ocg

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Rank 4 and Rank 5 Number Xyz monsters (Number 32, Number C32, Number 101, Number C101) that attack or negate through the WATER and Fish Shark engine; Armored and Full Armored Xyz lancers that gain ATK from materials (Full Armored Dark Knight Lancer, Full Armored Crystalzero Lancer)
• Turn 1 (going first): Open a WATER or Fish searcher or summon (Surfacing Big Jaws, Abyss Shark, Buzzsaw Shark, Hydrojet Shark) and convert it into a Rank 4 or 5 Xyz; Upstart Goblin and Seventh Ascension provide card flow (Inferred from card text)
• Turn 2 (going second): Use the two hand traps and Ice Barrier or Dominus Spiral to answer the opponent's first board, then rebuild the Xyz engine from the Graveyard with Crystal Shark and Xyz Remora (Inferred from card text)
• Recovery: Recur Shark and Fish monsters from the Graveyard through Crystal Shark, Silent Sea Nettle and Xyz Remora, and reuse Xyz materials for a second Number summon (Inferred from card text)
• After siding: No Side Deck is registered, so there is no post-side plan; the deck cannot adapt between games in a best-of-3

Why it scores here

The deck reliably opens a functional plan: the 17-copy archetype core gives about a 95 percent chance of at least one live starter in a 5-card opening hand (Inferred), and 12 searcher-text cards add redundancy. It converts that plan into pressure through a 15-card Xyz Extra Deck that covers Ranks 3 to 7 and includes Number C32 and Number 32 as boss monsters. Interaction is layered across Ice Barrier, Evenly Matched, Dominus Spiral, Virtue Stream and two negation-text Xyz, which supports continuing through disruption. The score comes from consistency, Extra Deck coverage and interaction read across the whole system, not from averaging the cards' individual scores. Archetype popularity earned no points: there is no tournament link, no recorded boards and no side deck, so combo ceiling and median are inferred from card text and post-side adaptability is scored at its floor.

Dimension scores

How the score was computed

Strategy profile: Midrange (D13 dropped and renormalised, because no dated meta sample exists). Structural ≈ 60, Going First ≈ 62, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: weak post-side plan (-3); redundant starter web (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 60.1 + TR 55 gives 59.1, then modifiers total -1 to give 58

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.05 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is dense (17 copies) with about a 95 percent chance of a live starter in 5 cards
• Extra Deck of 15 Xyz covers Ranks 3 to 7 with two copies of the key Number bosses
• Layered interaction across traps, negation-text Xyz and a removal-text Shark

Weaknesses

• No side deck, so the deck cannot adapt between games
• Low exact-name Shark purity (10.9 percent) and a spread of off-archetype engines
• Several situational traps (Xyz Revive Splash, Evenly Matched, Dominus Spiral) are weak without specific boards

Critical choke points

• Reliance on Xyz summons from the Extra Deck; a single disruption to the Xyz materials stalls the engine
• Going second with only 6 cards and 2 hand traps; a clean first-turn board can stop the Xyz route

Recommended changes

Evidence & confidence

• Verified: Legal status for OCG (Seventh Tachyon Limited 1/1, K9-17 Izuna Semi-Limited 2/2); Card stats and text for all 40 main and 15 extra cards; Archetype usage stats: core and missing core cards; Zero side deck cards
• Inferred: Consistency: P(at least 1 core in 5) 0.949 and brick proxy 0.051; Going-first and going-second plans from card text; Interaction density from negation and removal text; Xyz Extra Deck coverage and resilience
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format-fit (D13 dropped from Structural)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample No side deck list, so post-side adaptability is unmeasured
