Forbidden Deck #773142 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 15/100 (±5 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Kashtira Shangri-Ira / Kashtira Fenrir-style Kashtira beatdown built around Special Summoning Kashtira monsters and banish-based recursion (structural read from card text only); Xyz and Link boss monsters from the Extra Deck (Dark Armed, Number 11: Big Eye, Red-Eyes Flare Metal Dragon, Divine Arsenal AA-ZEUS)
• Turn 1 (going first): Open a Kashtira starter (Kashtira Unicorn or Fenrir, both currently illegal at this copy count) and search a Kashtira follow-up; the list has no recorded boards to confirm the line
• Turn 2 (going second): Use the 10 hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Infinite Impermanence) to break the opponent's first combo, then take over the board with Kashtira extenders
• Recovery: Searchers (20 copies of searcher text) and Kashtira Birth / Kashtiratheosis to rebuild from the GY and banish zones (Inferred from card text)
• After siding: Not applicable: the deck has 0 Side Deck cards, so no post-side plan exists

Why it scores here

The score is capped at 15 because the list is Illegal in OCG: three cards exceed their copy limits, and Kashtira Fenrir is Forbidden with three copies run. The structural read (about 49) is theoretical only and is not a normal Final Contextual score. The engine is reasonably accessible on paper: the Kashtira core has about a 55% chance of at least one piece in a 5-card opening hand, and 20 searcher-text cards lift the chance of finding a search effect to about 90%. Interaction is the strongest component, with 10 hand traps and 9 negation-text cards giving a 71% chance of at least one hand trap in a 6-card going-second hand. Off-archetype density is high (71 copies, 0% exact-name purity, with 34 level-0 Spell and Trap cards), and the deck has no Side Deck, so adaptability is near zero. Popularity and archetype usage were not credited, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-12). Final formula: Illegal cap: theoretical structural score 49 (Midrange weights); normal 0.80*Structural + 0.20*TournamentReliability would be ~46 but is not applied; final score capped at 15 because the list is Illegal (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.55 · 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

• Deep searcher density (20 searcher-text cards) gives high odds of finding a search effect
• 10 hand traps and 9 negation-text cards provide strong going-second interaction
• Extra Deck has real boss options: Shangri-Ira, Dark Armed, Red-Eyes Flare, Divine Arsenal

Weaknesses

• Illegal as built: Kashtira Fenrir is Forbidden and two other cards exceed their copy limits
• No Side Deck, so no post-side adaptability
• High off-archetype density (71 copies) and 34 level-0 Spell/Trap cards dilute the engine and add brick risk

Critical choke points

• Kashtira starter access depends on Kashtira Unicorn or Fenrir, which are illegal at the submitted copy counts
• Shangri-Ira and other Extra Deck bosses need Kashtira monsters on the field

Recommended changes

Evidence & confidence

• Verified: Legality: 56 Main and 15 Extra cards, with 3 copy-limit violations under the OCG ban list; Card text and composition counts from the evidence pack; Hypergeometric draw odds computed from the resolved list
• Inferred: Engine accessibility and brick estimates from probabilities and card text; Interaction quality read from hand-trap and negation text; Going-first and going-second estimates
• Provisional: Meta Power and format fit (no dated metagame sample)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record absent No win-rate telemetry in YGOVN Deck title is null and the archetype field is 'Forbidden', which is a ban-status label rather than a real archetype Meta Power is provisional without a dated metagame sample
