Kashtira Deck #538657 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Midrange
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Fusion Summon a 3000-ATK Dragon or Dracotail Fusion Monster (Dracotail Arthalion, Dracotail Gulamel, Filia Regis, Secreterion Dragon) from the Extra Deck using Dracotail and hand/field materials; Mulcharmy draw-engine pressure and Dracotail recursion from the GY over a long game; the Kashtira route is not functional because its Forbidden core is absent from legal copies
• Turn 1 (going first): Turn 1 Dracotail Faimena or Lukias discard/summon into a Dracotail searcher (Ketu/Rahu) or Dracotail Pan route to a Fusion, holding Ash Blossom and Droll as backup interaction
• Turn 2 (going second): Hold Ash Blossom, Ghost Reaper, Droll & Lock Bird and Nibiru in hand to stop the opponent's first Summon, then Fusion Summon once the board is stable
• Recovery: Recur Dracotail monsters and Spell/Traps from the GY and banishment via Dracotail Flame and Dracotail Horn, then rebuild a Fusion from the Extra Deck
• After siding: None: the Side Deck is empty, so the deck has no post-side plan and cannot adapt between games

Why it scores here

This is a Dracotail-Kashtira hybrid built on a Fusion engine, and it is illegal in TCG as submitted. Its Forbidden core (Kashtira Fenrir x3, Dimensional Barrier, Red-Eyes Dark Dragoon, Triple Tactics Talent) and 16 over-limit Limited and Semi-Limited copies mean the list cannot be played as built, so the score is capped to a theoretical structural read. Within that read, the deck has a reasonable Fusion route (searchers plus about 13 Fusion monsters) and strong interaction density (Ash Blossom, Droll & Lock Bird, Ghost Reaper, Nibiru, Artifact Lancea), which is what lifts it above the floor. Its weaknesses are a 19-card tech slot, 18 zero-Level spell and trap cards that open dead, and no side deck, so it cannot adapt after Game 1. No combo boards exist in the evidence, so floor, median and ceiling are text-only inferences. Popularity of the Kashtira archetype did not earn any points, and no card scores were averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 48, Going First ≈ 44, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); engine conflicts (-2). Final formula: Illegal cap applied (rubric Step 2): uncapped 0.80*48 + 0.20*40 - 12 (banlist exposure) = 34.4; capped to 25 as theoretical structural-only. Meta provisional (null).

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

• Dense negation and hand-trap coverage (Ash Blossom, Droll & Lock Bird, Ghost Reaper, Nibiru, Artifact Lancea).
• Searcher density (16 text hits) gives a high chance of finding a starter.
• Multiple 3000-ATK Fusion finishers in the Extra Deck.

Weaknesses

• Illegal as built: Forbidden cards and copy-limit violations.
• No Side Deck, so no post-side adaptability.
• Mixed archetypes (Dracotail, Mulcharmy, Kashtira, Eyes Restrict) dilute the engine.
• 18 zero-Level spell/trap cards and 19 tech cards cause brick risk.

Critical choke points

• The single Fusion Spell route (Polymerization, Super Polymerization) can be stopped by one negation.
• Starter access depends on the Dracotail searchers, and only 6 Dracotail core copies are in the deck.

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with 4 Forbidden cards and 16 over-limit copies; Main Deck 55, Extra Deck 15, Side Deck 0; Archetype core present: 2 of 25 (8%); exact name purity 4.3%
• Inferred: Starter P(>=1 searcher in hand of 5) ~0.83; Going-second hand-trap P(>=1 in 6) ~0.87; Engine conflict and brick estimates from composition and card text; Interaction density from negation and hand-trap text
• Provisional: Meta power (no dated sample); Matchup fit (no tournament link)
• 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 for going-first, going-second, matchups or brick rates Meta power is provisional without a dated metagame sample Side Deck is empty, so post-side plan cannot be evaluated
