Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 14 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos, Magician of Dark Chaos - Black Chaos or Black Luster Soldier, then convert the board into attacks and removal; Link and Fusion pressure from Extra Deck (Dragunity Lord - Georgius, Master of Chaos, Dark Magician of Destruction)
• Turn 1 (going first): Open Light and Darkness Ritual, Mind Shuffle, Griffoh or Skull Archfiend, use Ritual Spell to reach a level 8 Ritual monster; hold Ash Blossom or Kuriboh as the interaction layer
• Turn 2 (going second): Hand traps (Ash Blossom, Kuriboh, Evenly Matched, Solemn Accusation, Droll & Lock Bird) answer the opponent's first summon, then Mulcharmy draw and Ritual line rebuild the board
• Recovery: Skull Archfiend of Chaos from hand or GY returns banished or GY cards to the bottom of the Deck to Special Summon itself; Mulcharmy draw and Mind Shuffle refill the hand
• After siding: Not evaluable: side_count is 0, so no post-side plan exists

Why it scores here

The deck's opening engine is plausible: the archetype core (19 copies) gives an estimated 0.89 chance of at least one core card in a 5-card opening hand (Inferred), and Black Chaos, Magician of Dark Chaos and Black Luster Soldier reach 2800 to 3000 ATK boards once a Light and Darkness Ritual line is live. Interaction is the strongest area, with 13 negation-text cards and 7 hand traps spread across Ash Blossom, Kuriboh, Evenly Matched, Solemn Accusation, Droll and Lock Bird, giving layered answers to a going-second opponent. Consistency is held back by low on-theme purity (17.4% exact-name archetype copies, 57 off-archetype copies), 26 level-0 spells and traps, and single-copy Ritual Spells that make the engine fragile. The score is not earned from archetype popularity or from averaging card scores; the deck is Illegal (3 copies of two Semi-Limited cards), so its score is capped at 30 and labelled structural-only. No recorded boards, guides or tournament data exist, so the floor, median and ceiling are all Inferred from card text.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 52, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-8); illegal_cap (-11.6); no_side_deck (0). Final formula: No reliable metagame: 0.80*Structural(52) + 0.20*TournamentReliability(40) = 49.6, then -8 banlist exposure modifier = 41.6; capped at 30 because the deck is Illegal (over-limit Semi-Limited cards). Structural-only reading.

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

• Layered interaction: 13 negation-text cards and 7 hand traps
• Strong Ritual boss ceiling: Black Chaos, Magician of Dark Chaos and Black Luster Soldier at 2800 to 3000 ATK
• Deep Extra Deck link coverage (10 Link monsters)

Weaknesses

• Illegal list: 3 copies of two Semi-Limited cards
• Low archetype purity (17.4%); 26 level-0 spells and traps dilute the engine
• No side deck (side_count 0)
• Engine rests on single-copy Ritual Spells and Light and Darkness Ritual at 2 copies

Critical choke points

• Light and Darkness Ritual (2 copies) as the main Ritual Spell
• Black Chaos and Magician of Dark Chaos require 8 levels of Ritual material from hand or GY
• Mind Shuffle and Skull Archfiend are the only core searchers beyond Mulcharmy draw

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom and Dominus Impulse at 3 copies against a Semi-Limited limit of 2; Main 55 / Extra 14 / Side 0 counts and copy histogram; Card text for the core engine, interaction and Link cards (from evidence excerpts); Usage: Black Chaos 51%, Ash Blossom 98%, Mulcharmy Fuwalos 87% inclusion
• Inferred: Core starter access 0.89 at 5 cards (hypergeometric); Going-second and recovery plans from card text; Board ceiling from ATK values and ritual text
• Provisional: Meta Power is null; tournament_context is unavailable; Matchup fit (D13) provisional without dated metagame
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) No side deck, so post-side performance cannot be assessed No guides attached (total_guides 0) Deck title is null
