Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 8 violation(s).

Identity & game plan

• Win condition: Boss monsters from the Extra Deck (Ame no Murakumo no Mitsurugi 3200 ATK, Snakeeyes Flamberge Dragon 3000 ATK, Red-Eyes Dark Dragoon 3000 ATK, Dark Magician of Destruction 2800 ATK) after a Ritual or Fusion play; Fiendsmith's Lacrima and Azamina Mu Rcielago ATK/ATK-loss pressure once a Fusion is online
• Turn 1 (going first): Search a Light and Darkness Ritual / Fiendsmith / Snake-Eye starter, then reach a Ritual or Fusion with Light and Darkness Ritual, Pre-Preparation of Rites, Mitsurugi Ritual or Fiendsmith's Tract (Inferred)
• Turn 2 (going second): Same engine through the opponent's board with no hand traps in the list; relies on Magician of Dark Chaos and Black Chaos protection plus boss summons (Inferred)
• Recovery: Recycle via GY-triggered effects (Snake-Eye Oak, Fiendsmith's Requiem, Mind Shuffle, Light and Darkness Ritual GY effect) and dense searchers (Inferred)
• After siding: Not possible: side deck is empty (0 cards), so no post-side plan exists in this list

Why it scores here

This list cannot earn a normal contextual score because it is Illegal in TCG: Kashtira Fenrir (3 copies), Moon of the Closed Heaven and Original Sinful Spoils - Snake-Eye are Forbidden, and five Limited cards are run over their limit. The structural read is a Toolbox build with a large Extra Deck of ceiling-high bosses (Murakumo at 3200 ATK, Flamberge, Dark Dragoon), but its engines are split across Light and Darkness Ritual, Fiendsmith, Snake-Eye, Mitsurugi, Centur-Ion, Azamina and Diabellstar. The archetype-core proxy gives about a 52% chance of at least one core card in a 5-card opening hand, so roughly half of hands are functionally dead on the core engine (Inferred). With no side deck and no hand traps, the list has no going-second answer and no post-side plan. No recorded combos or tournament data exist, so the floor and median are inferred from text only. The score was not produced by averaging card scores, and the archetype's popularity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 46, Going First ≈ 48, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_exposure (-6); engine_conflicts (-4); no_side_deck (-2). Final formula: Structural 46.4 and TR 42 -> 0.80*46.4 + 0.20*42 = 45.5; modifiers -12 -> 33.5; Illegal cap -> 30 (theoretical/structural only, Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.52 · key two-card combo ≈ — · full-brick estimate ≈ 0.48 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong Extra Deck ceiling with 2800-3200 ATK bosses
• Dense searcher text (42 cards) gives draw consistency across sub-engines
• Protection and boss lines (Magician of Dark Chaos, Black Chaos) survive simple removal

Weaknesses

• Illegal list: 8 over-limit cards, 3 of them Forbidden
• Core engine present in only about half of opening hands
• No hand traps and no side deck, so no answer on going-second
• Sub-engines conflict and compete for slots

Critical choke points

• Light and Darkness Ritual / Ritual Monster access
• Fusion or Ritual material availability from Extra Deck

Recommended changes

Evidence & confidence

• Verified: Illegal status: 8 over-limit cards, including 3 Forbidden copies (Kashtira Fenrir, Moon of the Closed Heaven, Original Sinful Spoils - Snake-Eye); Main 60 and Extra 15 are within size rules; side 0; Exact archetype purity 9.3%; 68 off-archetype copies; Side deck empty (0)
• Inferred: About 52% chance of at least one archetype-core card in a 5-card opening hand (proxy); About 48% of opening hands lack a core card (brick proxy); Structural ceilings from card text (Murakumo, Black Chaos, Magician of Dark Chaos, Dark Magician of Destruction); Going-second weakness from zero hand traps and empty side deck
• Provisional: Meta Power (null) and D13 matchup fit: no dated metagame sample or tournament link
• Data gaps: No combos supplied: 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, matchup or brick rates Meta Power is Provisional unless a dated metagame sample is supplied
