Shark Deck #766009 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: duel-links

Legality

Main 20 / Extra 9 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Xyz chain through Number 101 / Number C101 / CXyz N.As.Ch. Knight, with Number-monster ATK growth and Valiant Shark Lancer / Number 4 removal closing the board; Gazer Shark and Stealth Kragen Spawn removal plus direct-damage text on Number 4 to finish the game
• Turn 1 (going first): Open a WATER Fish starter (Abyss Shark, Dream Shark, Surfacing Big Jaws, Buzzsaw Shark) to search or Special Summon a Level 4/5 Fish, then Xyz Summon into the Number line
• Turn 2 (going second): Use Droll & Lock Bird, Xyz Block, Forbidden Droplet and Blizzard to break the opponent's opening, then rebuild through Gazer Shark and the Extra-Deck Xyz line
• Recovery: Xyz Reborn and Xyz Revive Splash return a Rank 4 or lower Xyz from the GY, and Gazer Shark banishes from the GY to re-Xyz off two Level 5 WATER monsters
• After siding: Not applicable: Duel Links runs no Side Deck (side_count 0), so there is no post-side step

Why it scores here

The deck reliably opens its Shark starter layer: Abyss Shark (3 copies, about 60% to see one in a 5-card opening hand) and Droll & Lock Bird give the first turns a real plan, and the 9-card Extra Deck is fully populated with Number, CXyz and Stealth Kragen Xyz monsters that chain off each other. Its interaction suite (Xyz Block, Droll & Lock Bird, Forbidden Droplet, Blizzard, Gazer Shark, Valiant Shark Lancer) gives it layered answers that score well on end-board quality. It loses points for thin redundancy (eight singleton main-deck cards, two-copy starters, no recorded boards) and for having no Duel Links matchup or tournament data, so meta fit stays provisional. Popularity was not rewarded: the Shark archetype is established, but its score here comes from the list's own consistency, interaction and Extra-Deck coverage, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 58, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist_exposure (0); dependence_on_one_extra_card (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.6 · 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

• Fully populated 9-card Xyz Extra Deck with a coherent Number/CXyz/Stealth Kragen chain
• Layered negation and removal (Xyz Block, Droll & Lock Bird, Forbidden Droplet, Blizzard, Gazer Shark)
• Compact 20-card main deck with no bricks in the list itself and no banned or limited cards

Weaknesses

• Eight singleton main-deck cards and two-copy starters give limited redundancy for the opening hand
• No recorded boards, so the combo floor and median are unverified
• Several core support cards (Mulcharmy Fuwalos, Xyz Veil, Dark Hole, Triple Tactics Thrust, Hey, Trunade!) are missing from the main deck

Critical choke points

• The starter layer (Abyss Shark / Dream Shark / Surfacing Big Jaws) must be drawn before the Extra-Deck line can start
• Gazer Shark is the main GY-to-board engine, so losing it to a GY-hate or early removal interrupts recursion

Recommended changes

Evidence & confidence

• Verified: Legal in Duel Links: 20 main (range 20–30), 9 extra (range 0–9), 0 side, no violations, all cards Unlimited; Card text confirmed for Number 101, Number C101, CXyz N.As.Ch., Xyz Block, Droll & Lock Bird, Valiant Shark Lancer, Gazer Shark; Usage statistics: Mulcharmy Fuwalos 80% inclusion, typical 2 copies; core Shark pieces 100% inclusion
• Inferred: Abyss Shark opening-hand probability ~0.60 (3 copies, hypergeometric); Structural interaction and recursion quality from card text; Going-first and going-second strength from card roles, not from boards
• Provisional: Meta and format fit (D13): no dated metagame sample or tournament link; Post-side plan (D12): Duel Links has no Side Deck
• 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 usage_statistics matcher reports Number 4 (67557908), CXyz Barian Hope (67926903), N.As.H.
