Archfiend Deck #770076 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Ritual or Synchro/Link boss (Black Chaos, Black Luster Soldier, Red Nova Dragon, Chaos Angel) converting after an opening of Light and Darkness Ritual plus hand-trap protection; Mulcharmy draw-engine card advantage that grinds the opponent out of resources over a long round
• Turn 1 (going first): Search and set up a Ritual starter, using Ragged Records of Rites, Mind Shuffle and Soul Resonator to find pieces, then Ritual Summon a boss. Hand traps and Solemn cards are held for the opponent's turn.
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Ogre, Ghost Belle, Droll and Lock Bird, Maxx C) and negate the opponent's engine, then rebuild with a Ritual boss
• Recovery: Recycle from the GY with Skull Archfiend of Chaos and Mind Shuffle, and draw with Mulcharmy Fuwalos and Purulia once the hand is empty
• After siding: Not evaluable: the deck runs 0 side cards, so no post-side plan exists in the export

Why it scores here

The score is for the list as built, not for its legal standing. The list is Illegal: two Forbidden cards (Charmer Quartet in Bloom and Red-Eyes Dark Dragoon) are run at 1 copy each, which caps the final score low and makes the result structural-only. The structure is a Light and Darkness Ritual engine with Mulcharmy draw support and a large hand-trap and Solemn interaction package. That package is the strongest part of the deck, with about 11 hand traps and 3 Solemns giving a 76% chance of at least one hand trap going second. The engine is less reliable: the two-copy Ritual spell has only about a 17.5% chance of appearing in a 5-card opening hand, and the core set (9 copies, about 61% open rate) is only partly present. Only 4 of 12 archetype-core cards are in the list, so the deck is a related-family mix with an 'Archfiend' label rather than a clean Archfiend build. No combos or tournament record exist, so the score comes from consistency, interaction density and structure, with no averaging of individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Stun secondary (structural profile, not a blend). Structural ≈ 50.8, Going First ≈ 48, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal list cap (-20). Final formula: 0.80*Structural(50.8) + 0.20*TournamentReliability(45) = 49.6 (Meta provisional); Illegal-deck cap applied: -20 → 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.18 · 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 Solemn interaction (11 hand traps, 3 Solemns, plus Infinite Impermanence and Dominus Impulse)
• Searcher coverage (≈0.86 chance of at least one searcher in an opening 5)
• Multiple boss options at Ritual, Synchro and Link levels

Weaknesses

• Illegal list: two Forbidden cards over the copy limit
• Ritual starter access is low (2 copies of Light and Darkness Ritual, ≈0.18 in an opening 5)
• No side deck, so there is no post-side adaptation
• Archetype identity is mixed; the core archetype cards are mostly missing

Critical choke points

• Light and Darkness Ritual (2 copies) is the single most important starter and has about an 18% chance of appearing in an opening hand
• Both Forbidden cards must be removed before the list is playable

Recommended changes

Evidence & confidence

• Verified: Legality: 2 Forbidden cards over the copy limit; main 55 and extra 15 are within the OCG size rules; Composition: type, attribute and archetype-purity counts from the evidence export; Usage stats: only 4 of 12 core cards present (33%)
• Inferred: P(≥1 starter in opening 5) ≈ 0.18 and core-group open ≈ 0.61 (hypergeometric); Interaction density (11 hand traps, 3 Solemns) and going-second hand-trap probability ≈ 0.76; Dimension scores D1–D11 and D14 from card text and structure
• Provisional: Meta Power (null) and D13 matchup/format fit, with no dated meta sample or tournament link
• 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 and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck title is null and the archetype label (Archfiend) does not match the engine (Light and Darkness Ritual / Mulcharmy)
