Archfiend Deck #772587 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 62/100 (±6 · Confidence: Medium)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Red Dragon Archfiend and the high-ATK Synchro bosses it enables (Hot Red Dragon Archfiend Abyss, Red Nova Dragon - Burning Soul, Red Hypernova Dragon, Bystial Dis Pater); The Crimson King and Scarred Dragon Archfiend as Archfiend-mention Synchro follow-ups
• Turn 1 (going first): Open a Tuner starter (Bone Archfiend, Power Vice Dragon, Soul Resonator), search Red Dragon Archfiend through Crimson Gaia or Resonator Call, and Synchro into the boss
• Turn 2 (going second): Use a hand trap (Ash Blossom, Infinite Impermanence, Droll & Lock Bird, Maxx C) to break the opponent's starter, then Tuner plus Synchro into the boss
• Recovery: Recover Resonators from the GY (Synkron Resonator, Vision Resonator) and use Crimson Call to re-add a Level 4 or lower Fiend
• After siding: None: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck scores as a connected Synchro system, not as an average of its card scores. The Tuner density (about 16 Tuner copies) plus several three-copy starters makes a functional engine likely on most openings: the archetype core group gives P(at least one core card in a 5-card hand) of about 0.93, and the searcher group reaches about 0.89. Its ceiling comes from a chain into Red Dragon Archfiend and the 3000 to 4500 ATK Synchro bosses, and it carries strong interaction (ten hand-trap-type cards plus Lightning Storm, Dominus Impulse, Solemn Judgment and Feather Duster), which lifts endboard and going-second scores. The main deductions are the absence of recorded boards, so median output is inferred from text alone; the lack of any Side Deck, which removes post-side adaptability in a best-of-3 format; and six Limited plus two Semi-Limited restricted cards that cap consistency. Popularity did not earn points: archetype usage stats confirm the list is real and accessible but do not by themselves raise the score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 68, Going First ≈ 68, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: No side deck (-3); Banlist exposure (-2); Engine compactness (2). Final formula: 0.80*Structural(68.4) + 0.20*TournamentReliability(54) + ContextModifiers(-3) = 62 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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 Tuner engine with 16 Tuner copies and multiple three-copy starters
• Strong interaction layer: 10 hand-trap-type cards plus Lightning Storm, Dominus Impulse, Solemn, Feather Duster
• High ceiling from Red Dragon Archfiend into 3000 to 4500 ATK Synchro bosses
• All 15 Extra slots are Synchro and legal at the run count

Weaknesses

• No Side Deck, so no post-side adaptability in best-of-3
• Mulcharmy cards are dead when the field is occupied
• Low exact archetype-name purity (11.4%) means the engine relies on cross-archetype mentions
• No recorded boards, so the median output is inferred only

Critical choke points

• Red Dragon Archfiend (2 copies) and its Synchro summon path are the main win condition
• Single-copy restricted interaction (Maxx C, Droll, Feather Duster, Solemn) cannot be repeated if answered

Recommended changes

Evidence & confidence

• Verified: Legal OCG list: 55 Main, 15 Extra, 0 Side; all restricted copies within limit; Card text and stats from the evidence pack; Core-card usage stat: 61.1% of the archetype's core cards present
• Inferred: Starter access probabilities (hypergeometric); Combo ceiling and median from text read (no recorded boards); Interaction density and going-second board breaking; Engine recursion and interruption resilience
• Provisional: Matchup and format fit (no tournament or dated meta); Meta power (null); Post-side adaptability (no Side Deck)
• Data gaps: no combos supplied: combo floor, median, and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot match record absent no win-rate telemetry for going-first, going-second, matchup, or brick rates Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck, so best-of-3 side plans cannot be assessed
