Archfiend Deck #769359 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Archfiend Ritual and Fusion boards built from Throne of the Archfiends, Archfiend's Usurpation and Ritual of the Matador, closed by Archfiend Emperor, Scarlight Red Dragon Archfiend, Ashtraja Susanoo or Akasuna; Fusion Summons (Starving Venom, Favorite HERO Shining Flare Wingman, Mixousia) enabled by Super Polymerization
• Turn 1 (going first): Open with Mulcharmy Fuwalos or Royal Archfiend searchers, convert into an Archfiend Ritual through Throne or Usurpation, and hold Ash Blossom or Droll & Lock Bird for the first opponent interaction
• Turn 2 (going second): Use the six-card hand's hand traps (Ash Blossom, Infinite Impermanence, Forbidden Droplet, Droll & Lock Bird) to break the opponent's first board, then rebuild through Archfiend searchers
• Recovery: Archfiend Heiress, Archfiend Matriarch and Archfiend Strategy recycle Archfiend spells and monsters from the GY and banishment
• After siding: No side deck is registered, so there is no post-side plan to evaluate

Why it scores here

The deck opens reliably enough through its Archfiend searchers (16 searcher-text cards, P(at least one searcher in a 5-card opening hand) about 0.83) and three copies of the Throne and Usurpation lines, but its starter density per copy is modest, so the hypergeometric estimate of a live engine on turn one is only about 0.25 per triple-copy card (Inferred). Interaction is the strongest system feature: 7 hand traps, 13 negation-text and 14 removal-text cards give layered answers on both turns, which earns the D7 and D6 scores. The Extra Deck runs 15 cards with clear Ritual and Fusion access, but there is no recorded combo data, so ceiling and median output rest on text reading only and are scored conservatively. The deck is illegal in its format: three cards exceed their OCG copy limits and Aerial Eater is Forbidden, so the score is capped at a structural-only 35 and no tournament or popularity signal raised it. The score comes from consistency, interaction and closing power on the system, not from averaging individual card scores or from the Archfiend archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, no secondary weights applied. Structural ≈ 53, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist and copy-limit exposure (-8). Final formula: Structural 53 + modifiers -8 = 44, capped at 35 because the list is Illegal (no normal Final Contextual score); Meta provisional; Final = min(0.80*Structural + 0.20*TournamentReliability + modifiers, illegal cap 35)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Layered interaction: 7 hand traps plus Ash Blossom and Droll & Lock Bird
• Deep searcher suite (16 searcher-text cards) for rebuilding after a disruption
• Extra Deck covers Ritual and Fusion closers with high ATK

Weaknesses

• Illegal as built: three over-limit copies and one Forbidden card
• Low starter density per copy, with 27 level-0 spells and traps
• No side deck, so no post-side adaptability
• Only 2 of 12 archetype core cards are present in the list

Critical choke points

• Throne of the Archfiends or Archfiend's Usurpation as the single Ritual gateway
• Super Polymerization copy count, which is over the OCG limit

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0; sizes fit OCG rules (40-60 main, 0-15 extra); Over-limit copies: Pre-Preparation of Rites 3/1, Ash Blossom 3/2, Super Polymerization 3/2; Aerial Eater Forbidden; Attack and DEF values for Scarlight Red Dragon Archfiend, Ashtraja Susanoo and Akasuna; Extra Deck breakdown: 12 Fusion, 2 Synchro, 1 Link
• Inferred: Starter density and opening-hand consistency from the hypergeometric table; Interaction density from negation-text, removal-text and hand-trap counts; Midrange primary strategy and Toolbox secondary from the card mix
• Provisional: Meta Power and matchup fit: no dated metagame sample or tournament link
• Data gaps: no combos supplied; combo 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 and going-second rates are Inferred no side deck registered; post-side plan cannot be evaluated Meta Power provisional without a dated metagame sample
