Light and Darkness Ritual Deck #770501 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual boss pressure from Black Chaos, Black Luster Soldier and Magician of Dark Chaos - Black Chaos (3000/3000/2800), enabled by the single Light and Darkness Ritual Spell; Fusion and Link pressure (Azamina Sol Erysichthon, Azamina Mu Rcielago, Dark Magician of Destruction, Firewall Dragon) and Diabellstar / Skull Archfiend bodies
• Turn 1 (going first): Mulcharmy draw engine plus Diabellstar and searchers (WANTED, Witch of the Black Forest, Mind Shuffle) toward the Ritual Spell and a Ritual boss; hold Ash Blossom and Ghost Ogre for the opponent's first activation
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre and Snow Rabbit, Nibiru, Droll & Lock Bird) and Dominus Impulse to blank the opponent's first board, then Ritual or Fusion into a 2800-3000 ATK boss
• Recovery: Mulcharmy draws, Skull Archfiend recursion from GY or banish, Mind Shuffle to re-add a Ritual monster, and Dark Magical Curtain for a second Dark Magician route
• After siding: None: the deck runs 0 side cards in a format that allows up to 15, so there is no post-side plan

Why it scores here

The deck reliably opens a Light and Darkness Ritual or archetype piece (P(at least one archetype core card in a 5-card hand) is about 0.96, Inferred), but the path from that piece to a boss runs through a single copy of the Ritual Spell (about 9% to draw it in an opening hand of 5, Inferred). Its interaction density is respectable, with 11 hand traps, 8 negation texts and 20 removal texts, and the end-board ceiling is high (2800-3000 ATK bosses). The system is weakened by the list itself: 6 Forbidden cards are present, 4 cards are over their copy limit, and only 19.7% of cards are the exact archetype, so the spread across Dominus, Mulcharmy, Azamina, Sinful Spoils, Charmer and Kuriboh is closer to a toolbox than an engine. With zero recorded boards and no side deck, the median output and post-side plan cannot be measured and are scored from card text only. The score comes from consistency, median output and interaction read on the whole system; archetype popularity earned no points and card scores were not averaged. Because the deck is Illegal, the structural score of 49 is theoretical only and the final is capped at 28.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo secondary used only as a tie-break (not blended numerically). Structural ≈ 48.6, Going First ≈ 50, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); single-copy Ritual choke point (-2); no side deck (-2); illegal cap (0). Final formula: No dated meta, so Meta is provisional: raw = 0.80*48.6 + 0.20*35 + modifiers (-12) = 34; Illegal deck capped at 28. Structural 48.6 is theoretical only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · key two-card combo ≈ — · full-brick estimate ≈ 0.04 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is reliably accessible (about 0.96 in an opening hand, Inferred)
• Layered interaction: 11 hand traps plus negation and removal texts
• High-ATK Ritual and Dark Magician bosses (2800-3000) for the end board
• Draw and search density (Mulcharmy, Witch of the Black Forest, Mind Shuffle, WANTED)

Weaknesses

• Illegal list: 6 Forbidden cards and 4 over-limit cards
• Single Ritual Spell is the only route to the main boss
• Low archetype purity (19.7%) and a sub-archetype spread that dilutes the engine
• No side deck
• Extra Deck partly unusable as built (3 Forbidden Extra cards)

Critical choke points

• Light and Darkness Ritual Spell (1 copy): about 9% per opening hand of 5
• Forbidden Extra Deck cards: Azamina Ilia Silvia, Cross-Sheep, Charmer Quartet in Bloom
• Going-first hand with no hand trap or searcher

Recommended changes

Evidence & confidence

• Verified: Main 56, Extra 15, Side 0 counts are within the TCG size rules; Six Forbidden cards are present in the deck (Azamina Ilia Silvia, Called by the Grave, Charmer Quartet in Bloom, Cross-Sheep, Magicians' Souls, Triple Tactics Talent); Four cards are over their copy limit (Ash Blossom 3/2, Dominus Impulse 3/2, WANTED 3/1, Droll 2/1); Archetype core is 26 copies with 14 Light and Darkness Ritual-named cards and 19.7% exact-name purity; Zero recorded boards and zero side deck cards
• Inferred: P(>=1 archetype core card in 5-card hand) about 0.96; Ritual Spell P(>=1 in 5) about 0.09 makes the main boss route fragile; Interaction density from card text (11 hand traps, 8 negations, 20 removal texts); Going-second hand-trap coverage about 0.75 in a 6-card hand; Structural 48.6 and Final 28 under the Illegal cap
• Provisional: Meta Power null: no dated metagame sample; Matchup and format fit (D13) with no tournament context; Tournament reliability 35 from text and brick proxy
• 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 in YGOVN: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is provisional without a dated metagame sample Deck title is null; the deck is Illegal, so the final is a capped theoretical score
