Legality

Main 41 / Extra 15 / Side 0 — status: Illegal. 1 violation(s). Restricted cards run: Called by the Grave (Limited), Fairy Tail - Snow (Limited), Foolish Burial (Limited), Foolish Burial Goods (Limited), Keldo the Sacred Protector (Limited), Maxx "C" (Limited), Mudora the Sword Oracle (Limited), Tearlaments Havnis (Limited), Tearlaments Kashtira (Limited), Tearlaments Kitkallos (Limited), Tearlaments Sulliek (Limited), Super Polymerization (Semi-Limited), Tearlaments Scheiren (Semi-Limited).

Identity & game plan

  • Win condition: Tearlaments Kashtira + OTK/FTK via banished Fusion/Synchro/Xyz materials and board-wide effect negation; Tearlaments Rulkallos floodgate + disruption to stall and recycle resources
  • Turn 1 (going first): Play Kashtira Fenrir or S:P Little Knight on T1, set backrow, use Call by the Grave/Tearlaments Kashtira/Tearlaments Rulkallos to disrupt and search, establish board control, then pivot to Tearlaments combo or stall into OTK by turn 4-5.
  • Turn 2 (going second): Six-card hand with Ash Blossom, King's Sarcophagus, Super Polymerization, multiple Tearlaments, and Fenrir; answer threats with Call by the Grave/Tearlaments Cryme/Mudora, search Kashtira/Rulkallos, then out OTK around turn 3-4 using banished materials.
  • Recovery: If combo disrupted, recycle via Foolish Burial Goods/Scream/Rulkallos effect, re-establish Fenrir/Key beaters, and use Kashtira floodgate to slow opponent while grinding resources.
  • After siding: Side into additional Ash Blossom, King's Sarcophagus, and floodgates; remove opponent's key enablers and add hand traps to mitigate their follow-up.

Why it scores here

The deck runs a clearly defined Kashtira-FTK/OTK plan centered on Tearlaments and board-wide negation, giving strong combo ceiling and above-average going-second disruption. However, it is fragile: a poor opening (no Fenrir or key traps), a single dead card (Super Polymerization over limit), or targeted hand traps can brick hard, producing a low floor. Consistency is dragged down by strict extra deck requirements and limited searchable recursion, while light vulnerability to backrow hate and format-specific restrictions further depresses real-world reliability.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 7-core cards present (Kashtira Fenrir, S:P Little Knight, Call by the Grave, Tearlaments Kashtira/Rulkallos/Cryme/Havnis) yielding 62.9% open chance; inferred as Inferred from probabilities and counts (Inferred).
D2 Opening-Hand Quality & Brick Management — 40-card main with 3×Ash Blossom, 3×Super Polymerization creates brick risk; opening hand quality rated poor due to narrow key density (Inferred).
D3 Combo Conversion & Ceiling 80 Best line chains banished materials into OTK by turn 4–5 with high ceiling (Observed from combo summary and best_line inference).
D4 Combo Floor & Median Output — Median output limited by brick potential and disruption; estimated around turn 5–6 with modest board presence (Inferred).
D5 Interruption Resilience & Route Redundancy 50 Redundant answers exist (Call by the Grave, Cryme, Mudora) but single dead cards can collapse lines; resilience rated average (Inferred).
D6 Resource Economy, Recovery & Grind 65 Resource loop via re-summon/floodgate plus handtrap-to-draw supports moderate grind (Observed from card text and extra recursion).
D7 End-Board & Interaction Quality 70 Strong interaction density with multiple negate/remove options and 16 searcher copies (Observed from role_tag_counts).
D8 Going-Second & Board-Breaking Power 75 Going-second plan leverages six-card quality and strong counter tools (Observed from hand-trap group and probabilities).
D9 Offensive Pressure & Closing Power 70 High-ATK targets (Imsety 3000, A Bao A Qu 2800) plus board clear enable closing (Observed from best_line and stat spreads).
D10 Main Deck Efficiency & Flexibility — 41-card main with 28 distinct cards and 3×key staples creates moderate flexibility but reliance on specific pieces reduces efficiency (Inferred).
D11 Extra Deck Efficiency & Coverage — Extra deck filled with 7 fusion/link including high-impact Kashtira Rulkallos and A Bao A Qu, showing strong coverage (Observed from extra breakdown).
D12 Side Deck Adaptability 50 Side options exist but no post-side data prevents confident adaptation rating; provisional due to lack of evidence (Provisional).
D13 Matchup Coverage & Format Fit 40 Illegal status and narrow archetype focus hurt format fit; meta share and matchup data absent, rating capped low (Provisional).
D14 Pilotability & Error Tolerance — Many discrete decisions (searches, banish timing, equip choices) increase complexity and error surface (Inferred).

How the score was computed

Strategy profile: Balanced (primary Combo with resilience emphasis). Structural ≈ 58, Going First ≈ 60, Going Second ≈ 70, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal Super Polymerization copy count (-4); No post-side performance data (-3); Format restriction and meta absence (-6). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ — · 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

  • Clear FTK/OTK plan via Tearlaments + board negation
  • Strong going-second disruption with multiple hand traps and counters
  • High interaction density and resource recursion
  • Above-average end-board ATK potential with Imsety/A Bao A Qu

Weaknesses

  • Illegal Super Polymerization count creates consistency issues
  • Low brick rate but high variance — can easily draw dead
  • Narrow archetype purity and limited searchable recursion
  • No post-side data and limited format evidence
  • Many one-of tech pieces increase pilot error surface

Critical choke points

  • Dependence on specific extra deck pieces (Kashtira Rulkallos, Tearlaments key cards)
  • Super Polymerization over limit risking dead hands
  • Lack of reliable floodgate without full extra suite
  • No reliable recovery once combo is interrupted early
Priority Remove Add Reason
1 Super Polymerization (reduce to 2 or consider alternate quick-play) Additional Ash Blossom / hand traps or alternate searcher Reduce illegality and smooth draws to raise floor
2 More consistent extra recursion (e.g., additional Tasigur / Cry / common searchers) Improve median output and reduce brick variance
3 Tech answers for common backrow and counter cards in the format Raise real-world reliability against format-specific hate

Evidence & confidence

  • Verified: legality status and restriction list; card text and role tags; probabilities from deck statistics; extra deck breakdown
  • Observed: best_line inference from recorded boards; resource_signature and interaction_density_avg
  • Inferred: brick rate and consistency estimates; combo floor/median/ceiling where no boards exist; hand-trap effectiveness and going-second potential; pilotability and error tolerance from step complexity
  • Provisional: meta power without dated metagame sample; matchup coverage and post-side adaptability; format fit without current tournament data
  • Data gaps: no recorded match data or win-rate telemetry no parseable combo boards for median/ceiling calculation no post-side deck performance data no current format meta sample to contextualize power
