Legality

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

Identity & game plan

  • Win condition: Kashtira / Tearlaments boards (Kashtira 2300 bodies, Rulkallos/Kaleido-Heart/Zombie Vampire 3000-ATK extra-deck threats) once a Tearlaments engine is live; Fusion beatdown through Super Polymerization and Tearlaments Merrli/Havnis fusion-summon chains
  • Turn 1 (going first): Open a searcher (Tearlaments Scream, Perlereino, Tearlaments Grief, Engraver) and Special Summon Scheiren/Havnis/Merrli to set up a Fusion or Kashtira board, protected by Ash and Droll
  • Turn 2 (going second): Hand traps (Ash x3, Droll, Solemn) and Forbidden Droplet to answer the opposing board, then rebuild through Tearlaments Reinoheart and Scream recursion
  • Recovery: Recover through Tearlaments Scream, Reinoheart, Sulliek and Metanoise searches; the Fiendsmith core that would normally recover is absent
  • After siding: Not possible: side deck is empty (0 cards), so there is no post-side plan

Why it scores here

The deck is scored on its system, not on an average of card scores. Its main consistency asset is a 19-card searcher pool, which gives about 0.89 chance of at least one searcher in a 5-card opening hand (Inferred). Its archetype core is thin: only 4 Fiendsmith-named copies, 66 off-archetype copies, and 2 of 11 usage-core cards present, so the engine does not reliably come online. Interaction is the strongest area, with 4 hand traps and 11 negation-text and 16 removal-text cards, which lifts going-second and end-board scores. There are no recorded boards, no tournament data, and no guides, so combo floor, median, and ceiling are text-only inference at low confidence. The list is Illegal under OCG copy limits (5 overages) and has no side deck, which caps the Final score as a theoretical, structural-only reading.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 40 Searcher pool gives ~0.89 at-least-one in hand5, but only 4 archetype-core copies and 2 of 11 usage-core cards present (Inferred; usage stats Verified)
D2 Opening-Hand Quality & Brick Management 45 10 triple-copy slots and 19 searchers reduce brick risk, but 4 hand traps and many tech cards add dead-card risk (Inferred)
D3 Combo Conversion & Ceiling 35 No recorded boards; ceiling from text only, e.g. Kashtira plus Rulkallos/Kaleido-Heart lines (Inferred)
D4 Combo Floor & Median Output 35 No recorded boards; median cannot be measured, so scored as text-only prior (Inferred)
D5 Interruption Resilience & Route Redundancy 50 Redundant Tearlaments searchers and recursion give some route redundancy, but the Fiendsmith core is absent (Inferred)
D6 Resource Economy, Recovery & Grind 50 Scream, Reinoheart and Sulliek recursion and search text provide some grind; no resource signature data exists (Inferred)
D7 End-Board & Interaction Quality 70 Ash x3, Droll, Solemn, Droplet, Cryme, Metanoise and Trivikarma give layered negation and removal text (Inferred semantic read of card text)
D8 Going-Second & Board-Breaking Power 60 Four hand traps and Droplet give strong going-second answers; board-breaking depends on Kashtira and Fusion boards (Inferred)
D9 Offensive Pressure & Closing Power 60 Several 3000-ATK extra-deck bodies (Rulkallos, Kaleido-Heart, Zombie Vampire, Imsety, Radian) carry closing power (Verified stats, Inferred use)
D10 Main Deck Efficiency & Flexibility 45 55 main-deck cards with 32 distinct entries and 5.7% exact-archetype purity; compactness is poor (Verified composition, Inferred consequence)
D11 Extra Deck Efficiency & Coverage 50 15 Extra-Deck slots run 8 Fusion, 4 Link, 3 Xyz with mixed archetypes, so coverage is wide but not coherent (Verified breakdown)
D12 Side Deck Adaptability 10 Side deck is empty, so there is no post-side adaptability (Verified)
D13 Matchup Coverage & Format Fit 45 No dated metagame or tournament link; archetype share unavailable (Provisional)
D14 Pilotability & Error Tolerance 40 Multiple engines and conditional summons across three archetypes raise decision load (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 47, Going First ≈ 48, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Banlist exposure (-4); No side deck (-3). Final formula: No reliable metagame: 0.80*Structural(47) + 0.20*TournamentReliability(38) + modifiers(-7) = 38 theoretical; capped to 25 because the list is Illegal (over copy limit in 5 cards)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.89 · 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

  • 19 searchers give high probability of a search in the opening hand
  • Layered negation and removal (Ash x3, Droll, Solemn, Droplet, Cryme, Metanoise)
  • Several 3000-ATK extra-deck threats

Weaknesses

  • Illegal under OCG copy limits in 5 cards
  • Fiendsmith core absent (2 of 11 usage-core cards present)
  • No side deck
  • Very low exact-archetype purity (5.7%)

Critical choke points

  • Ash Blossom & Joyous Spring and Droll as the only protection for the engine
  • Tearlaments searcher density as the only route to the Fusion/Kashtira payoffs
Priority Remove Add Reason
1 Tearlaments Kashtira x2 (keep 1) Legal filler or a second Fiendsmith core card Restores legality; the copy limit is 1 in OCG
2 Ash Blossom & Joyous Spring x1, Super Polymerization x1, Primeval Planet Perlereino x1 Legal copies within limit or a Fiendsmith core card Restores legality at the 2-copy limit
3 Fiendsmith Engraver x1 Fiendsmith's Requiem or Sequence (not present) Engraver is Limited to 1 in OCG; the missing core cards would make the engine coherent
4 Off-archetype tech A 15-card side deck covering the opponent's common boards A zero-card side deck gives no best-of-3 adaptation

Evidence & confidence

  • Verified: Illegal status: 5 copy-limit violations under OCG BanList; Main 55 / Extra 15 / Side 0 (size rules satisfied for main and extra; side 0 is legal); Exact-name archetype purity 5.7%; core present 2 of 11; Archetype usage stats available
  • Inferred: Searcher hypergeometric estimate 0.89 at least one in hand5; Interaction density read from card text; Engine accessibility and brick estimates
  • Provisional: Meta power and matchup fit: no dated metagame sample
  • Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and pilot record absent no win-rate telemetry for this deck no side deck: post-side plan cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
