Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 59 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Magician of Dark Chaos - Black Chaos off Light and Darkness Ritual, then extend into board pressure (theoretical, text-only); Link and Fusion pressure from Mediclius, Artmage Diactorus and Dark Magician of Destruction once a Power Patron or Artmage line is live
• Turn 1 (going first): Open Griffoh, Mind Shuffle or Light and Darkness Ritual to search, then Ritual Summon through Black Chaos; hold Ash Blossom and Ghost Ogre for the first disruption
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Ogre, Infinite Impermanence, Nibiru, Droll) to stop the opponent's first summon, then rebuild via Mulcharmy draws
• Recovery: Mulcharmy draw effects when the hand is empty, Mind Shuffle and Ragged Records of Rites to re-add Ritual cards and Ritual Spells from the Deck
• After siding: Not evaluable: the deck runs no Side Deck (Side Deck size 0), so no post-side plan exists in the export

Why it scores here

The deck's engine is a Ritual chain built around 23 archetype-core copies, which gives a 92% hypergeometric chance of at least one core card in a 5-card opening hand (Inferred). Its interaction density is high, with 14 hand traps and several negation or removal spells, and this is what drives the going-second score. However, the list has no recorded boards, so floor, median and ceiling are text-only inferences and are not reported as averages of card scores. The deck also runs three sub-archetype engines (Mulcharmy draw, Power Patron Link and Artmage Fusion) at only 13.5% exact-name purity, which costs consistency and pilotability. The list is Illegal: 5 Forbidden cards and 2 over-limit Limited or Semi-Limited cards, so the score is structural-only and capped at 35. Archetype popularity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*52 + 0.20*45 - 12 = ~38; capped at 35 because legality is Illegal (structural-only score per rubric Step 2)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and negation suite (14 hand traps) gives strong going-second interaction
• Core archetype cards are heavily represented (23 copies), so the engine is usually present in the opening hand
• Redundant starters and draw effects (Mulcharmy, Griffoh, Kuriboh) give multiple routes after a single disruption

Weaknesses

• Illegal list: 5 Forbidden cards and 2 over-limit cards, so no normal score is possible
• No Side Deck, so there is no post-side plan at all
• Three competing engines (Mulcharmy, Power Patron Link, Artmage Fusion) with 13.5% exact-name purity
• Mulcharmy draw effects conflict with the card-in-hand requirement of the Ritual plan
• No measured combo data, so the ceiling and median are unverified

Critical choke points

• Light and Darkness Ritual (1 copy) is the only direct Ritual starter; its absence leaves the Ritual line dependent on Mind Shuffle or Griffoh searches
• Black Chaos requires a Spellcaster or Warrior Ritual monster in hand or GY to be Special Summoned
• Two Extra Deck slots (Red-Eyes Dark Dragoon, Cross-Sheep) are Forbidden and must be replaced

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: 5 Forbidden cards and 2 over-limit cards are present (legal copies from the export); Main 59 and Extra 15 are within the TCG size rules; Side 0 is legal but empty; Archetype core group 23 copies with P(>=1 in hand of 5) = 0.9247; Hand-trap group 14 copies with P(>=1 in hand of 6) = 0.8192; Usage stats: Magician of Dark Chaos - Black Chaos and Ash Blossom each at 100% inclusion
• Inferred: The Ritual engine can reach Black Chaos from its starters; based on card text only; Interaction density is high, based on hand-trap and negation text hints; Going-second strength comes from hand-trap density; Mulcharmy draw effects conflict with the card-in-hand Ritual plan
• Provisional: Meta Power is null: no dated metagame sample; Matchup fit (D13) is unmeasured: no tournament context
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck in the export: post-side performance cannot be assessed
