Light and Darkness Ritual Deck #774657 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 6 violation(s).

Identity & game plan

• Win condition: Ritual boss pressure from Black Chaos, Magician of Dark Chaos - Black Chaos and Black Luster Soldier (3000 ATK class bodies, text-only read, Inferred); Fusion and Link pressure from Tearlaments Kaleido-Heart, Tearlaments Rulkallos and Fiendsmith's Desirae (text-only read, Inferred)
• Turn 1 (going first): Open Tearlaments and Fiendsmith searchers plus Light and Darkness Ritual to reach a ritual boss; the cross-engine starter mix makes T1 lines unreliable (Inferred)
• Turn 2 (going second): Hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Kuriboh - Multiply!, Nibiru) to answer the opponent's first board, then a ritual or fusion follow-up (Inferred)
• Recovery: Search and recursion through Tearlaments Scream, Mind Shuffle, Skull Archfiend of Chaos and Tearlaments Heartbeat to rebuild from the GY (Inferred)
• After siding: Not assessable: the deck runs no side deck (side_count 0), so there is no post-side plan

Why it scores here

This list is Illegal: it runs Kashtira Fenrir (Forbidden) and three copies each of several Limited or Semi-Limited cards, so it receives a theoretical, structural-only score capped at 25. The structural read of 52 comes from the system rather than from averaging card scores: the archetype core is reasonably likely to appear in an opening hand (about 86%, Inferred), searcher text is near-universal (about 96%), and there are many hand traps and interaction cards. Those strengths are offset by three competing engines (Kashtira, Tearlaments and Fiendsmith) with no coherent route between them, a 60-card main deck with 13 tech slots, and no side deck. Popularity and archetype usage are not counted as power, and the absence of combo records, tournament data and guides keeps confidence Low.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary is recorded but not blended into the numbers (Inferred). Structural ≈ 52.1, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-8); Engine conflicts (-4); No side deck (0); Illegal cap (-12). Final formula: Structural 52.1 with Midrange weights; TR 40. Unclamped 0.80*52.1 + 0.20*40 = 49.7, then modifiers -12 gives 37.7. Illegal status caps the score at 25 (theoretical/structural-only, no normal final score).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · key two-card combo ≈ — · full-brick estimate ≈ 0.14 (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 appear in an opening hand about 86% of the time (Inferred)
• Searcher text is near-universal (about 96% of openings) (Inferred)
• Layered hand-trap and negation suite for going second (Inferred)
• Several 3000-ATK boss bodies provide closing power (Inferred)

Weaknesses

• Illegal list: Forbidden Kashtira Fenrir and six over-limit cards (Verified)
• Three competing engines with no shared line (Inferred)
• 60-card main with 13 tech slots and low compactness (Verified count)
• No side deck, so no post-side plan (Verified)
• No combo, tournament or guide evidence (Verified gap)

Critical choke points

• Kashtira Fenrir is Forbidden and cannot be played as built (Verified)
• Core ritual route depends on Light and Darkness Ritual plus a Ritual Monster in hand or GY (Inferred)

Recommended changes

Evidence & confidence

• Verified: Illegal status and six over-limit cards; Forbidden status for Kashtira Fenrir; Main 60, Extra 15, Side 0 within size rules; Archetype core inclusion about 86% in a 5-card hand
• Inferred: Engine conflicts across Kashtira, Tearlaments and Fiendsmith; Combo ceiling and ritual boss pressure from text only; Hand-trap density and going-second value; Midrange primary strategy
• Provisional: Meta Power (null, no dated meta sample); Matchup fit (D13, no tournament data)
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck (side_count 0), so post-side performance cannot be assessed
