Kashtira Deck #772879 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Kashtira Xyz/Link board (Shangri-Ira, Fenrir/Unicorn/Ogre beatdown) fed by Kashtira searchers and Kashtiratheosis / Birth recursion; Going-second hand-trap and negate protection that buys time for the Kashtira board
• Turn 1 (going first): Open a Kashtira starter (Riseheart, Kashtiratheosis, Birth) plus a searcher; summon a Level 7 Kashtira and build toward Shangri-Ira, using Harpie's Feather Duster or Solemn Judgment for spell/trap interaction
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Nibiru, Mind Over Matter) to stop the opponent's first summon or activation, then rebuild the board from the GY and banished Kashtira
• Recovery: Search Kashtira Fenrir/Unicorn/Ogre or Kashtira Trap/Spell from the Deck, then re-summon from banish or GY through Kashtira Birth and Kashtira Preparations
• After siding: Not defined: the deck has no Side Deck, so no post-side adjustments are possible. Any side-deck plan is unevaluated

Why it scores here

The score comes from how the Kashtira system behaves across the list, not from averaging its cards. The deck has 16 searcher-text cards and 12 hand traps, so it can usually find a Kashtira starter and hold some interaction. The core Kashtira set is thin: P(at least one of the 7 core copies in a 5-card opening hand) is about 0.51, so roughly half of openings lack the archetype core, and 30% of the main deck is exact-name Kashtira. Interaction is broad (37 removal-text and 15 negation-text cards), which is why end-board interaction scores well. The structure is strongly penalized by the Illegal status: three Kashtira Fenrir are Forbidden in OCG, Kashtira Unicorn and Ash Blossom exceed their copy limits, and the deck has no Side Deck. The result is capped as theoretical and structural only. Meta share and archetype popularity earned no points, and no combo data exists to support a ceiling or median read.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-10); no_side_deck (-2); illegal_cap (-8). Final formula: Illegal cap applied: 0.80*Structural(54) + 0.20*TournamentReliability(45) = 52, minus banlist and side modifiers (-12, clamped) = 40, then capped to 30 as theoretical/structural-only per rubric Step 2

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · 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

• Searcher density (16) gives good odds of finding a Kashtira starter
• Broad interaction: removal-text 37 and negation-text 15, plus 12 hand traps
• Level 7 Kashtira bodies and Shangri-Ira give a strong end-board

Weaknesses

• Illegal list: Forbidden and over-limit cards
• Core Kashtira presence in opening hand is about 51%
• Only 30% exact-archetype purity; the deck is diluted with off-archetype staples
• No Side Deck

Critical choke points

• Kashtira Fenrir (Forbidden) is a core searcher and body; without it the list is not legal
• Opening without a Level 7 Kashtira starter forces a slow, interaction-only game

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main / 15 Extra / 0 Side; Forbidden Fenrir and over-limit Unicorn and Ash; Card text for the Kashtira core and interaction cards; Usage statistics: Ash 80% inclusion, Fenrir 60%, Harpie's Feather Duster 57%
• Inferred: Core open probability 0.51 and searcher-group probability 0.83 (hypergeometric); Interaction density and hand-trap timing estimates from card text; Structural scores across the 14 dimensions
• Provisional: Meta Power and matchup fit (no dated metagame); Median and floor output (no recorded boards)
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry; going-first and going-second splits are Inferred or Unknown Meta Power is Provisional without a dated metagame sample No Side Deck; post-side plan cannot be evaluated
