Archfiend Deck #769955 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 37/100 (±10 · Confidence: Low)

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

Legality

Main 50 / Extra 20 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Red Dragon Archfiend-line Synchro boards (Tyrant Red Dragon Archfiend, Hot Red Dragon Archfiend Bane, Red Nova Dragon) if the Extra Deck is trimmed to a legal size; Ordinary Synchro pressure from Red Dragon Archfiend, Hot Red Dragon Archfiend Abyss and The Crimson King
• Turn 1 (going first): Search a Resonator tuner with a searcher (Soul Resonator, Power Vice Dragon, Crimson Gaia) and Synchro Summon into a 3000+ ATK Dragon; text-only read, not a verified line
• Turn 2 (going second): Open a six-card hand with a searcher and 2 hand traps (Ash Blossom, Red Mirror), then rebuild through Resonator chains; hand-trap odds are low (P at least one hand trap in 6 is about 0.23, Inferred)
• Recovery: Recover through the searchers in the Deck and GY (Resonator Command, Crimson Call, Synkron Resonator); searcher density is high (P at least one searcher in 5 is about 0.96, Inferred)
• After siding: Not evaluable: the deck has no side deck, so no post-side plan exists

Why it scores here

The list is Illegal: its Extra Deck holds 20 cards against an OCG maximum of 15, so it gets no normal Final Contextual score and this result is structural only. Copy limits are respected (Bystial Magnamhut and The Bystial Lubellion at 1 each under Limited, Ash Blossom & Joyous Spring at 2 under Semi-Limited). The Main Deck's search density is the main strength: 23 searcher-text cards give a high chance (about 0.96, Inferred) of at least one searcher in an opening 5. The Archfiend engine itself is thin, with only 2 Red Dragon Archfiend copies (P at least one in 5 is about 0.19, Inferred), 16 exact-name Archfiend cards out of 70 copies (22.9% purity), and 25 generic copies. The deck's Extra Deck has 5 cards that are not part of the archetype's core, and 3 of the 12 archetype-core usage cards are missing. No combo boards, tournament link, guides, or win-rate data exist, so floor, median, and ceiling are text-based inferences only. The score was not built by averaging card scores, and popularity did not add points. The legality failure caps the final score low.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary (rubric hybrid rule, disclosed). Structural ≈ 53, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: Illegal Extra Deck size (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers, with the Illegal cap applied via the extra-deck size modifier (Meta provisional): 0.80*53.3 + 0.20*30 - 12 = 36.6, rounded to 37

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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 searcher and Resonator access (23 searcher-text cards)
• Strong Synchro closers (Tyrant Red Dragon Archfiend 3500, Hot Red Dragon Archfiend Bane 3500, Red Nova Dragon 3500, Red Supernova Dragon 4000)
• Broad interaction text (18 removal-text, 7 negation-text cards)

Weaknesses

• Illegal: 20 Extra Deck cards against a maximum of 15
• Only 2 Red Dragon Archfiend copies, so the core engine card is hard to find
• Low archetype purity (22.9% exact name) with 25 generic copies
• No side deck
• Missing 7 of 12 archetype-core usage cards

Critical choke points

• Red Dragon Archfiend (2 copies) is the common gate to the top-end Synchro boards
• Extra Deck legality: at 20 cards the list cannot be played as built

Evidence & confidence

• Verified: Extra Deck holds 20 cards, above the OCG maximum of 15; Copy limits respected: Bystial Magnamhut 1/1 (Limited), The Bystial Lubellion 1/1 (Limited), Ash Blossom & Joyous Spring 2/2 (Semi-Limited); Main Deck 50 cards; side deck 0 cards; Exact-name archetype purity 22.9%; 3 of 12 usage-core cards present in the list (5 of 12 by usage-core count)
• Inferred: Searcher density gives a high chance of at least one searcher in an opening 5 (about 0.96); Red Dragon Archfiend access is low (about 0.19 for at least one in 5); Interaction and resilience scores come from card text, not recorded boards
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link exists
• 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, matchup, brick, starter, OTK rates) Meta Power is provisional unless a dated metagame sample is supplied No side deck, so post-side plan cannot be assessed Export lists the extra-deck overage only as a size warning; its violations array is empty
