Shark Deck #766545 — Yu-Gi-Oh! Duel Links

Deck — Deck Power Evaluation

Final Contextual Deck Power: 64/100 (±6 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Xyz pressure from the Extra Deck: Number 101 / Number C101 / N.As.H. Knight ladder and Stealth Kragen Spawn, fed by WATER hand-summons (Dream Shark, Abyss Shark, Surfacing Big Jaws, Crystal Shark) and the Gazer Shark graveyard loop.; Gazer Shark banishes from the GY to summon two Level 5 WATER monsters and Xyz Summon from them, recurring the engine after a board wipe or trade.
• Turn 1 (going first): Hand-summon a WATER starter (Dream Shark or Abyss Shark, which require an all-WATER board or empty board) and use its effect to add or send Xyz material toward a Level 4/5 Number Xyz, then build toward Number 101 or N.As.H. Knight.
• Turn 2 (going second): Respond to the opponent's Special Summons with Gazer Shark, Xyz Block, or Number 101 (attach an opposing summoned monster), then rebuild from the GY via Gazer Shark and Stealth Kragen Spawn.
• Recovery: Gazer Shark loop from the GY using two Level 5 WATER monsters (Dream, Abyss, Crystal), plus Xyz Revive Splash to restore a Rank 4 or lower Xyz.
• After siding: Not applicable: Duel Links is single-game and the deck runs no Side Deck (side_count 0).

Why it scores here

The deck opens a functional plan reliably: nine main-deck cards can be Special Summoned from hand under WATER-board or Spell-activation conditions, and the probability of at least one such starter in a 5-card opening hand is about 0.97 (Inferred, hypergeometric over the resolved list). Conversion is supported by a full nine-card Extra Deck of Xyz monsters with overlapping material requirements (Number 101, Number C101, N.As.H. Knight, Stealth Kragen Spawn), and the floor is held up by Gazer Shark's graveyard loop. Interaction is layered but conditional: Xyz Block, Gazer Shark, Number 101 and Stealth Kragen Spawn cover negation and removal, while Dark Hole is a self-hurting one-copy wipe. The score comes from consistency, recursion, and interaction on the system, not from Shark being a popular archetype and not from averaging card scores; the usage stats only confirm the list resembles the standard core. Two structural defects cost points: two Mulcharmy Fuwalos (WIND) conflict with the WATER-only hand-summon conditions, and D/D/D Wave High King Caesar cannot be summoned from this main deck because it needs two Level 6 Fiends.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 65.9, Going First ≈ 68, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: Dead Extra Deck slot (-2); Engine conflict (-1); Redundant hand starters (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null) = 0.80*65.9 + 0.20*62 - 1 = 64.1

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · key two-card combo ≈ — · full-brick estimate ≈ 0.03 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Nine hand-summon starter copies across four distinct cards give high opening-hand access.
• Full nine-card Extra Deck of Xyz monsters with overlapping material routes (Number 101, Number C101, N.As.H. Knight, Stealth Kragen Spawn).
• Gazer Shark graveyard loop provides recursion after a board wipe or trade.
• Layered negation and removal: Xyz Block, Gazer Shark, Number 101, Number 4 / Stealth Kragen Spawn.

Weaknesses

• Six of 20 main slots are conditional spells/traps.
• Two Mulcharmy Fuwalos (WIND) conflict with the WATER-only hand-summon conditions.
• D/D/D Wave High King Caesar needs two Level 6 Fiends the main deck does not contain.
• No hand traps and no tech cards.

Critical choke points

• WATER-board condition on Dream Shark and Abyss Shark hand summons; a WIND Mulcharmy on the field can shut them off.
• Number C101 on the field is required for CXyz Barian Hope and the Number C101 route; losing it removes that line.

Recommended changes

Evidence & confidence

• Verified: Legal in duel-links: 20 main (range 20-30), 9 extra (range 0-9), 0 side.; Hey, Trunade! is Semi-Limited with 2 legal copies, 1 run.; Card text for the Xyz, hand-summon and negation effects, from the card excerpts.; Hypergeometric draw odds (1, 2, 3 copies) match the list (20-card main).
• Inferred: At least one hand-summon starter in a going-first 5-card hand ~ 0.97.; Engine conflict between Mulcharmy (WIND) and WATER-only hand summons.; Caesar is unsummonable from this main deck (no Level 6 Fiend).; Floor, median and ceiling are text-based estimates, not recorded output.
• Provisional: Meta power and matchup fit (no dated meta sample; tier signal is a stale 2024 guide).; Side-deck adaptability (not applicable in Duel Links; neutral placeholder).
• Data gaps: No recorded combo boards (combos_evidence total_combos 0): floor, median and ceiling are text-based only. usage_statistics in_this_deck flags 9 Extra Deck cards (Number 4, CXyz Barian Hope, Number 101, N.As.H. Knight, Number C101, CXyz N.As.Ch. Knight, D/D/D Caesar, Stealth Kragen Spawn, Number 71) as absent, although the card list shows them in the extra zone. The core_present_pct of 60.9 is therefore an artifact of the join; all 23 tracked core cards are present in the list. No tournament link: archetype meta-share and per-pilot match record absent. The only tier signal is a 2024 guide snippet (Tier 3), which is stale. No win-rate telemetry exists for going-first, going-second, matchup or brick rates. Meta Power is provisional: no dated metagame sample supplied.
