Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Ritual Summon Black Chaos / Magician of Dark Chaos - Black Chaos / Black Luster Soldier via Light and Darkness Ritual, then close with 2800-3000 ATK boards and Extra Deck beaters; Synchro and Fusion beaters (Chaos Angel, The Dragon that Devours the Dogma, Mirrorjade) once a Ritual or Fallen of Albaz line is online
• Turn 1 (going first): Open with Mulcharmy / Griffoh / Ghost Ogre-type starters and searchers (Mind Shuffle, Ragged Records, Nadir Servant) to fetch the Ritual Spell or a Ritual monster, then convert through Black Chaos or Black Luster
• Turn 2 (going second): Hold hand traps (Ash Blossom, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Nibiru, Griffoh) to slow the opponent's first summons, then Ritual Summon or Fusion through the surviving board
• Recovery: Recover through Ragged Records, Skull Archfiend of Chaos GY effect, Mind Shuffle, and Mulcharmy draw effects; Black Chaos can re-place a Continuous Trap from the GY
• After siding: Not evaluable: the deck has no side deck, so there is no post-side plan

Why it scores here

The deck can reliably open a searcher-and-starter turn, since 17 searcher-text cards give about an 86% chance of at least one in the opening five (hypergeometric, Inferred). Its single Light and Darkness Ritual spell is the only copy of the ritual enabler, so the Ritual engine itself is fragile; the 0.09 chance of drawing it in five cards is what holds D1 down. Hand traps (13 cards, about 82% for at least one in six going second) and recursion give it real interruption resilience and going-second interaction, and the 2800 to 3500 ATK closers give strong end-board pressure. The score is not earned from Light and Darkness Ritual being a known archetype, and no card scores were averaged; the deck is capped because it is illegal (Forbidden Albion and Called by the Grave, plus three over-limit cards) and has no side deck, so this is a structural read only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52.5, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (Forbidden cards in deck) (-8); copy-limit overage (-4). Final formula: Structural 52.5 (Midrange profile) → 0.80*52.5 + 0.20*40 = 50; modifiers −12 → 38; capped to 20 because status is Illegal (theoretical/structural-only). Meta Power is Provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · 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

• Dense hand-trap and removal-text package (13 hand traps, 19 removal-text cards)
• Strong closing bosses at 2800 to 3500 ATK across Main and Extra Deck
• High searcher density (17) gives frequent access to the engine pieces

Weaknesses

• Illegal list: two Forbidden cards and three over-limit cards
• Only one Light and Darkness Ritual spell, making the ritual engine fragile
• Empty side deck, so no post-side adaptation
• 55-card main deck dilutes consistency; 14 singleton slots

Critical choke points

• Single copy of Light and Darkness Ritual gates the Ritual boss line
• Forbidden cards (Albion, Called by the Grave) must be removed before the deck is playable

Recommended changes

Evidence & confidence

• Verified: Main 55 / Extra 15 / Side 0 counts vs TCG size rules; Albion the Branded Dragon and Called by the Grave are Forbidden; Branded in High Spirits, Droll & Lock Bird and Ash Blossom exceed legal copies; Archetype exact-name purity 18.6%; Searcher group 17 copies; hand-trap group 13 copies
• Inferred: Hypergeometric opening-hand odds (searcher 0.86; Ritual spell 0.09; hand traps 0.82 going second); Interaction and closing-power reads from card text; Engine fragility from a single Ritual spell copy
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit (D13) with no tournament context
• 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; going-first/second and brick rates are Inferred no side deck, so post-side performance cannot be assessed Meta Power is Provisional unless a dated metagame sample is supplied
