Kashtira Deck #765730 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: master-duel

Legality

Main 60 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Extra Deck bosses from Kashtira and Red-Eyes Xyz, Fusion and Link routes (Kashtira Shangri-Ira, Kashtira Arise-Heart, Red-Eyes Darkness Metal, Red-Eyes Black Fullmetal, Red-Eyes Dark Dragoon, Master of Chaos) converting a board into pressure; Dragon Ruler (Tempest) and Red-Eyes recursion lines that rebuild the board through the Graveyard after interruption
• Turn 1 (going first): Open with a 2-copy Kashtira starter (Riseheart, Fenrir, Unicorn or Ogre) or Kashtira Birth, using Ash Blossom, Infinite Impermanence and Maxx C to protect the first Summon, then move into a Level 7 Xyz route
• Turn 2 (going second): Use the 6-card hand's hand traps (7 copies total) to answer the opponent's first board, then Special Summon a Kashtira starter from hand or the banished or GY zone and build toward a Shangri-Ira or Arise-Heart Xyz
• Recovery: Searchers (22 cards with search text) and Kashtira Birth/Preparations reconstitute the starter after a broken turn, with Red-Eyes Black Metal Dragon and Dragon-based recursion as the second route
• After siding: No Side Deck is registered (side_count 0), so no post-side plan is evidenced; this is scored as a gap, not as a weakness of the main

Why it scores here

The deck is a Kashtira and Red-Eyes Dragon hybrid whose 60-card main is built around 22 searcher-text cards (P(at least one in a 5-card opening hand) about 0.91) feeding a 2-copy Kashtira starter layer; the chance that a given 2-copy starter is in the opening hand is about 0.16, so a turn-1 engine is far from assured, and this is what holds D1 at 62 rather than higher. Interaction is the strongest system feature: 7 hand traps (Ash Blossom, Infinite Impermanence, Maxx C), 9 negation-text cards and 25 removal-text cards give a going-second hand-trap chance of about 0.54, which earns D7 70 and keeps D5 at 60. The 15-card Extra Deck offers several boss routes (Shangri-Ira, Arise-Heart, Red-Eyes Darkness Metal, Red-Eyes Black Fullmetal, Master of Chaos), supporting D9 72 and D3 68 on text evidence alone. The score does not reflect popularity: the Kashtira archetype is named on only 13 of 75 archetype-tagged copies (17.3% exact-name purity), and the 15 Red-Eyes copies plus Dragon Ruler and generic staples are scored as a system cost in D10/D11 and the engine-split modifier, not as an average of card scores. There are no recorded boards, no dated meta sample and no side deck, so D4, D12 and D13 are provisional and the band is held at plus or minus 7.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.5, Going First ≈ 60, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist_exposure (-1); engine_split_hybrid (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); 0.80*59.5 + 0.20*52 = 58.0, modifiers -3 = 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.16 · 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 and hand-trap layer that makes the first turns resilient
• Several high-ATK Extra Deck bosses across Xyz, Fusion and Link routes
• Strong text-level interaction: 7 hand traps plus 9 negation and 25 removal effects

Weaknesses

• Two archetype cores (Kashtira and Red-Eyes) compete for the same slots: only 13 exact Kashtira copies
• No Side Deck, so there is no evidenced post-side adaptation
• Starter density is low per copy: 2-copy starters appear in an opening hand about 16% of the time

Critical choke points

• Kashtira Shangri-Ira (the single Level 7 Xyz that most routes depend on; one Extra Deck card)
• The 2-copy Kashtira starter layer (Riseheart, Fenrir, Unicorn, Ogre): if all are dead, the Xyz route cannot start from hand

Recommended changes

Evidence & confidence

• Verified: Legal list: 60 Main, 15 Extra, 0 Side against Master Duel size rules 40-60 / 0-15 / 0-15; Restricted cards: Maxx C, One for One, Predaplant Verte Anaconda, Pressured Planet Wraitsoth Limited (1 copy each); Kashtira Unicorn Semi-Limited (2 copies); Copy histogram and Extra Deck breakdown reconcile with the card list (60 and 15); Archetype purity: 13 exact Kashtira copies, 17.3%
• Observed: No recorded boards for this deck; combos_evidence.total_combos = 0
• Inferred: P(>=1 searcher in 5) about 0.91 and P(>=1 two-copy starter in 5) about 0.16 (hypergeometric); Hand-trap chance going second about 0.54; Interaction and boss-route scores from card-text excerpts
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (D13, no tournament context); Median and floor (D4), no combo data
• Data gaps: Data conflict: S:P Little Knight appears in the card list (Extra zone, 1 copy) but usage_statistics marks it in_this_deck = false; the card list was treated as the source of truth and the Extra Deck count of 15 reconciles with it No combos supplied: combo floor, median and ceiling are text-only inference (D3/D4) No tournament link: no archetype meta-share and no per-pilot match record No win-rate telemetry; going-first and going-second splits are Inferred Meta Power is Provisional without a dated metagame sample No Side Deck in the export; post-side plan cannot be evaluated
