Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Kashtira Xyz boss (Shangri-Ira / Arise-Heart) or Red-Eyes / Fullmetal pressure, built on Kashtira searchers and banish-based interaction; Fusion boss (Dark Magician of Destruction, Master of Chaos, Red-Eyes Dark Dragoon) once Polymerization or Ready Fusion is live
• Turn 1 (going first): Search a Kashtira monster or Kashtira Birth, Normal Summon a Level 7 monster without Tribute, then Xyz or Fusion into a boss while holding Ash Blossom and Infinite Impermanence
• Turn 2 (going second): Use the six-card hand to present a hand trap (Ash Blossom, Maxx C, Infinite Impermanence) against the opponent's first summon, then rebuild a Kashtira board from the GY or banish with Kashtira Fenrir or Unicorn
• Recovery: Kashtira searchers (Fenrir, Unicorn, Ogre, Wraitsoth, Kashtiratheosis) and Red-Eyes searchers (Black Metal Dragon, Meteor Dragon) refill the hand; Kashtira Preparations and Kashtira Birth recur banished or GY Kashtira monsters
• After siding: Not applicable: this format has no sideboard in use (side_count 0), so there is no post-side plan to evaluate

Why it scores here

The deck is a Kashtira shell with a large off-archetype component: only 13 of 60 main-deck copies are named Kashtira, and Red-Eyes, Swamp, Metalmorph, Dragon Ravine and Dragon Ruler-adjacent cards pull in different directions. Its consistency is moderate: the Kashtira core group is open in a five-card hand only about 42% of the time, while the 22 searcher-text cards give roughly 91% at least one searcher in hand, so the deck usually finds something to do but often not its intended engine. Interaction is the stronger side of the system, with 7 hand traps, 9 negation-text cards, and 25 removal-text cards giving layered answers to the first summon and to the end board. Offensive closing power is good because the Xyz and Fusion bosses (Shangri-Ira, Arise-Heart, Fullmetal, Darkness Metal, Dark Magician of Destruction) carry 2800 to 3400 ATK. The score does not come from Kashtira being a popular archetype, from the average of the card scores, or from any recorded combo or win-rate data, because none exists for this deck. Median output and matchup fit remain unmeasured and are the largest reasons the band is wide.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 54.6, Going First ≈ 52, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine conflicts (-4); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then context modifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.42 · 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

• Layered interaction: 7 hand traps plus negation and banish text across the deck
• Strong Xyz and Fusion bosses with 2800 to 3400 ATK
• Dense searcher text (22 cards) gives high odds of a searcher in hand

Weaknesses

• Kashtira core is only 13 copies with 17.3% exact-archetype purity; the list reads as a toolbox rather than a focused engine
• Several Extra Deck and main-deck cards have little synergy with the core (Hieratic, Linkuriboh, Predaplant, Dragon Shrine)
• Kashtira Shangri-Ira and Arise-Heart need Kashtira materials the deck only partly supplies
• Limited and Semi-Limited copy exposure (Maxx C, One for One, Verte Anaconda, Wraitsoth, Unicorn)

Critical choke points

• Kashtira core group is open in a 5-card hand only about 42% of the time
• Single-copy staples (Maxx C, One for One, Wraitsoth) are unrecoverable if they are dead or banished

Recommended changes

Evidence & confidence

• Verified: Deck is legal: 60 main, 15 extra, 0 side within format size rules; Restricted cards are within their legal copy limits (Maxx C 1/1, One for One 1/1, Verte Anaconda 1/1, Wraitsoth 1/1, Unicorn 2/2); Kashtira core usage stats: Ash Blossom 100% inclusion, Fenrir 83% inclusion; S:P Little Knight 100% inclusion but absent from this list
• Observed: Composition counts: 13 exact-archetype copies, 17.3% purity; type spread and extra-deck breakdown
• Inferred: Core group open rate ~0.42 and searcher presence ~0.91 from hypergeometric estimates; Hand-trap presence going second ~0.54; Structural and functional read of engine conflicts and closing power from card text
• Provisional: Meta Power (null) and matchup fit: no dated metagame sample; Tournament reliability is estimated from consistency and interaction dimensions, not from match data
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry for going-first, going-second, matchup, or brick rate Meta Power is provisional without a dated metagame sample Master Duel side deck is not used in the list, so post-side performance cannot be assessed
