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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Luster Soldier or Magician of Dark Chaos - Black Chaos, then extend into Synchro and Fusion boards (Inferred from card text); Going-second Ash Blossom, Ghost Belle and Maxx C interaction into a Fusion or Synchro follow-up (Inferred from card text)
• Turn 1 (going first): Open Light and Darkness Ritual or a Ritual monster plus a Mind Shuffle or Mulcharmy search, then Ritual Summon into a 3000-ATK boss (Inferred)
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Maxx C, Droll and Lock Bird) to answer the opponent's first summon, then rebuild the Ritual or Fusion line (Inferred)
• Recovery: Recover from the GY through Ragged Records of Rites, Skull Archfiend of Chaos and Light and Darkness Ritual GY effects (Inferred from text)
• After siding: Not evaluable: side deck is empty (0 cards), so no post-side plan exists

Why it scores here

The deck is an Illegal OCG list (55 Main, 15 Extra, empty Side) that runs Albion the Branded Dragon, which is Forbidden, and three copies of Branded in High Spirits against a limit of one, so it is scored as a theoretical, structural-only read capped low. Its engine is coherent on paper: 21 copies of the archetype core give about 92% odds of at least one core card in a 5-card opening hand, and the Ritual bosses (Black Luster Soldier, Magician of Dark Chaos - Black Chaos) are backed by a dense interaction suite of about 10 hand traps and 21 removal or negation texts. The weak point is the Ritual Spell itself, which is a single copy with roughly 9% odds of appearing in an opening 5-card hand, so the core line depends on searchers and Mind Shuffle rather than on the Spell being live. Consistency is further hurt by 30 distinct main cards, only 21% exact-name archetype purity, and no combo data to confirm real boards. The score comes from consistency, interaction and boss power on the system, not from the archetype's popularity and not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (approximately 80/20 by judgement). Structural ≈ 51, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*51 + 0.20*40 - 12 = 28.8, then capped at 25 because the deck is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Core archetype cards are heavily represented (21 copies, about 92% to open at least one)
• Dense interaction: about 10 hand traps plus negation and removal text
• High-power Ritual bosses (3000 and 2800 ATK) with protection text
• Multiple recovery routes from the GY via searchers and Ritual Spell effects

Weaknesses

• Illegal list: Albion the Branded Dragon (Forbidden) and three copies of Branded in High Spirits (Limited, 1 allowed)
• Single Ritual Spell copy makes the core Ritual line unreliable
• Low exact-name archetype purity (21.4%) and 30 distinct main cards reduce coherence
• No Side Deck at all (0 cards), so no post-side adaptation
• No combo or tournament data to confirm real performance

Critical choke points

• Light and Darkness Ritual (1 copy) is the single Spell gating the Ritual boss line
• Legal fix required before any normal score: remove Albion and reduce Branded in High Spirits to 1 copy

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: Albion the Branded Dragon is Forbidden (run 1) and Branded in High Spirits is Limited (run 3, allowed 1); Main Deck 55, Extra Deck 15, Side Deck 0; Main and Extra sizes are within OCG limits; 21 copies of the archetype core, 10 hand traps, 15 searchers, 21 removal texts; Exact-name archetype purity 21.4%
• Inferred: Core engine opens at least one piece in 92% of opening 5-card hands; Ritual Spell (1 copy) appears in an opening 5-card hand about 9% of the time, making the Ritual line unreliable; Hand traps are live in about 72% of going-second 6-card hands; Boss-level closing power from Black Luster Soldier and Magician of Dark Chaos
• Provisional: Meta Power and matchup fit are unknown without a dated metagame sample
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot record are absent No win-rate telemetry for this deck Side Deck is empty, so post-side adaptability cannot be measured Legality is Illegal, so the score is theoretical and structural only
