Shark Deck #768852 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 50 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Xyz boss plays from the Extra Deck (Number 104 Masquerade, Number C104 variants, K9-X Werewolf, Number 69 Dark Matter Demolition) reached through searcher-driven Xyz Summons; Heraldic Beast and K9 Xyz lines that recycle Heraldic Beast or K9 monsters from the Graveyard into a second Xyz
• Turn 1 (going first): Open with a searcher (Mulcharmy draw engine, Surfacing Big Jaws, Heraldic Beast Stad Whale, Thousand Umbral Horror, Seventh Ascension) into a 2-card Xyz bootstrap, then use Ash Blossom and Droll as protection
• Turn 2 (going second): Hand-trap first (Ash Blossom, Droll & Lock Bird, Shining Umbral Horror draw), then rebuild from the Graveyard with Heraldic Beast or K9 recursion into a 2-material Xyz
• Recovery: Graveyard recursion (Gorgonic Umbral Horror, Heraldic Beast Gryphon, K9 monsters) and Barian's Hope or Barian's Seventh Untopia to refill the hand after a disruption
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck opens a functional plan reliably on paper: P(at least one of the 18 archetype-core copies in a 5-card opening hand) is about 0.905, and P(at least one searcher-text card) is about 0.944 (Inferred). Conversion into pressure is plausible through the Extra Deck boss monsters (Number 104 Masquerade, Number C104 variants, K9-X Werewolf, Number 69 Dark Matter Demolition, all 2300 to 3300 ATK), but the list has no recorded boards, so the ceiling and median are text-only inferences. Interaction is dense (Ash Blossom, Droll and Lock Bird, Barian's Seal, Masquerade-style negates, K9 Quick-Play effects) and gives the deck a real end-board plan. The score is capped hard because the list is illegal: Ash Blossom and K9-17 Izuna each run three copies against an OCG limit of two, and the deck has no Side Deck. Popularity and the shark archetype name earned no points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary, disclosed as 2:1 weighting. Structural ≈ 54, Going First ≈ 52, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (over copy limit) (-6); Engine conflicts across sub-archetypes (-4); No Side Deck (-2). Final formula: 0.80*Structural(54) + 0.20*TournamentReliability(45) + ContextModifiers(-12) = 40, then capped to 30 because the list is Illegal (over copy limit on Ash Blossom and K9-17 Izuna). Meta Power provisional/null. Result is theoretical/structural-only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · 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

• Dense searcher text (21 cards) gives a high chance of a functional opening (Inferred)
• Layered interaction: hand traps, Xyz negates, Droll, Barian's Seal (Inferred)
• High-ATK Extra Deck bosses at 2700 to 3300 ATK (Verified)

Weaknesses

• Illegal copy counts on Ash Blossom and K9-17 Izuna (Verified)
• No Side Deck (Verified)
• Very low archetype purity: 1.5 percent exact-name; 64 off-archetype copies (Verified)
• No recorded boards, so the ceiling and median are unmeasured (Verified gap)

Critical choke points

• Single-archetype core is 18 copies spread across sub-archetypes; a single Xyz material miss can end the line (Inferred)
• Ash Blossom and Droll as the only hand-trap protection on the going-second turn (Inferred)

Recommended changes

Evidence & confidence

• Verified: Main 50, Extra 15, Side 0; within OCG size rules (40-60, 0-15, 0-15); Ash Blossom & Joyous Spring x3 and K9-17 Izuna x3 over OCG limit of 2; Limited cards (A Case for K9, Droll & Lock Bird, Seventh Tachyon) run 1 copy each, legal; Boss ATK values and archetype purity counts
• Inferred: Opening-hand probabilities (0.905 core, 0.944 searcher, 0.41 hand-trap on going second); Engine conflict and brick estimate from sub-archetype spread; Interaction quality from card text and negate hints; Pilotability estimate from the number of sub-engines
• Provisional: Meta Power (no dated metagame sample); Matchup and format-fit scoring (D13)
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry in YGOVN: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck and no title on the deck
