Identity & game plan

Win condition: Xyz Summon a Number, Stealth Kragen or CXyz boss from the Extra Deck, fed by hand-summoned WATER starters, then close with ATK pressure; Negation- and removal-backed boards that hold the opponent's monsters off while Xyz recursion rebuilds
Turn 1 (going first): Turn 1: hand-summon Abyss Shark, Dream Shark or Surfacing Big Jaws, search or set up Xyz material, then Xyz Summon from the Extra Deck
Turn 2 (going second): Use Droll & Lock Bird and the Xyz Block / Forbidden Droplet negations to stop the opponent's first board, then Xyz Summon on the follow-up turn
Recovery: Xyz Reborn and Xyz Revive Splash return a Rank 4 or lower Xyz from the GY; Number monsters and Stealth Kragen Spawn can recur from the GY
After siding: No side deck is run (side 0); there is no post-side plan in this list

Why it scores here

The deck is scored as a system: it reliably opens a hand-summon starter (11 monster copies in 20 Main Deck cards gives roughly 0.99 chance of at least one in an opening hand of 5) and converts it into Xyz Summons from a 9-card Extra Deck with several Rank 4 to 7 bosses. Its interaction layer (Droll & Lock Bird, Xyz Block, Forbidden Droplet, Blizzard and the monster-based negations and removal) is layered enough to hold a first board, and the recursion cards (Xyz Reborn, Xyz Revive Splash, Number and Stealth Kragen Spawn) give it a second route after disruption. Points are held back for the lack of recorded boards (floor and median are text-inferred only), for the missing side deck, and for the unknown matchup picture, so popularity and archetype usage were not credited. No card scores were averaged or summed into this result.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	70	P(at least one starter in 5) ≈ 0.99 across 11 hand-summon monster copies; Xyz material routes depend on which starter lands (Inferred)
D2	Opening-Hand Quality & Brick Management	60	Three Xyz recursion or trap cards and the conditional Big Jaws/Dream Shark summon conditions create some dead-hand risk; no brick estimate beyond the hypergeometric proxy (Inferred)
D3	Combo Conversion & Ceiling	60	Ceiling is an Xyz line into a 2800-ATK boss with negation and recursion support; no recorded boards exist to confirm it (Inferred)
D4	Combo Floor & Median Output	45	Median output is unobserved because no boards were supplied; floor is pulled down by the single-starter 1-copy cards (Inferred)
D5	Interruption Resilience & Route Redundancy	60	Several independent hand-summon starters and two recursion trap routes give redundancy, but the Xyz core is concentrated in one Extra Deck family (Inferred)
D6	Resource Economy, Recovery & Grind	62	Recursion through Xyz Reborn, Xyz Revive Splash and Number monsters plus 5 searcher-text cards provide grind value (Inferred)
D7	End-Board & Interaction Quality	68	Five negation-text and six removal-text cards, plus Gazer Shark and the Stealth Kragen destroy effect, layer interaction across the end board (Inferred)
D8	Going-Second & Board-Breaking Power	62	Droll & Lock Bird (3 copies) and Xyz Block / Forbidden Droplet give going-second answers to a board; 3 hand traps in a 6-card hand gives about 0.68 coverage (Inferred)
D9	Offensive Pressure & Closing Power	74	Boss ATK reaches 2800 (C101, Caesar) and CXyz Barian Hope gains 1000 ATK per material; direct-attack text is not confirmed (Inferred)
D10	Main Deck Efficiency & Flexibility	66	20 Main Deck cards at the minimum size with 13 distinct cards, but the 3 off-archetype and tech slots dilute the core (Verified count, Inferred read)
D11	Extra Deck Efficiency & Coverage	70	All 9 Extra Deck slots are Xyz monsters that share the Shark/Number/Stealth Kragen engine, with overlap in material routes (Inferred)
D12	Side Deck Adaptability	20	No side deck is registered in this Duel Links list, so there is no post-side adaptation to evaluate (Verified, Provisional score)
D13	Matchup Coverage & Format Fit	50	No tournament link or dated meta sample supplied; the archetype usage data only confirms the list is a real, accessible build (Provisional)
D14	Pilotability & Error Tolerance	55	Multiple Xyz chains and Quick Effect timings (Number material swaps, Stealth Kragen destruction) raise the decision count; the core line is repeatable with practice (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 61, Going First ≈ 64, Going Second ≈ 61, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: No side deck / no post-side plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.99 · 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

Consistent hand-summon starter density (11 monster copies in 20 Main Deck cards)
Nine Xyz bosses with several 2500+ ATK options and multiple material routes
Layered interaction: 5 negation-text and 6 removal-text cards
Two independent recursion routes for Xyz monsters

Weaknesses

No side deck, so no post-side adaptation
No recorded boards, so ceiling and median are inferred only
Three off-archetype or tech slots (Blizzard, Forbidden Droplet, Droll & Lock Bird) dilute the core
Xyz core is concentrated in one Extra Deck family

Critical choke points

Turn 1 starter plus Xyz material: if the opening hand has only one starter and no material route, the Xyz line stalls
Going second, the opponent's first board needs a negation (Xyz Block or Forbidden Droplet) to be stopped

Recommended changes

Priority	Remove	Add	Reason
1	Blizzard	Xyz Veil	Usage data shows Xyz Veil in 75% of Shark lists versus Blizzard's narrow spell-only negation; this is usage-based, and Xyz Veil's card text is not in the evidence

Evidence & confidence

Verified: Legality: 20 Main / 9 Extra / 0 Side, Legal under BanDuelLink; All copy counts and banlist status (all Unlimited); Archetype usage stats: 23 core rows, 9 present; Guide snippets: 2 guides attached
Inferred: Starter probability (≈0.99) from hypergeometric estimate; Floor, median and ceiling scores from card text; Interaction and recursion layers from card text; Going-first and going-second estimates
Provisional: Matchup coverage and format fit (no tournament or dated meta sample); Meta Power (null)
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 no win-rate telemetry exists in YGOVN — going-first/second, matchup and starter/brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck — post-side performance cannot be evaluated
