Archfiend Deck #771792 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 41/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon DARK Dragon/Archfiend bosses (Red Dragon Archfiend, Hot Red Dragon Archfiend Abyss/Bane, Scarlight/Scarred) and attack through a hand-trap-protected board; Bystial Dis Pater / The Crimson King / Draco Berserker of the Tenyi as alternative 3000+ ATK boss routes
• Turn 1 (going first): Open a starter (Bone Archfiend, Crimson Gaia, Resonator Call or Soul Resonator) and Synchro into a 3000-ATK Red Dragon Archfiend route, holding Ash Blossom or Ghost Belle to protect the Synchro
• Turn 2 (going second): Use the 6-card hand to hold a hand trap (Ash Blossom, Ghost Ogre, Ghost Belle, Effect Veiler, Infinite Impermanence, Nibiru) against the opponent's first summon, then rebuild the Synchro line on the following turn
• Recovery: Search Resonator or Archfiend monsters with Crimson Gaia, Vision Resonator and Earthbound Prisoner Stone Sweeper, and re-summon from the GY via Red Rising Dragon or Hot Red Dragon Archfiend Abyss effects
• After siding: Not applicable: the list has no Side Deck, so no post-side plan exists (theoretical only)

Why it scores here

The deck is scored as a system: 18 Archfiend-core copies give a high probability of an opening starter (about 0.96 with at least one core card in a 5-card hand, Inferred), and 16 searchers plus Resonator and Crimson Gaia text let it chain access into a Synchro Summon. Its interaction is the strongest part: 18 hand-trap or tech cards and 12 negation effects give about a 98% chance of a hand trap on the going-second 6-card hand (Inferred), which earns the going-second and interaction dimensions. Conversion is limited by the lack of recorded boards, so the ceiling (Red Dragon Archfiend, 3000 ATK) is text-only and the median is scored low (no combo data). The deck has no Side Deck, so adaptability and matchup fit are scored low or left provisional, and the Ash Blossom copy count is illegal, which caps the final score. Popularity of the archetype did not add points, and no individual card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange profile weights; Toolbox noted, not blended. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy limit (Ash Blossom x3, OCG limit 2) (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 52.8, then -12 illegal copy-limit modifier = 41 (theoretical/structural-only, illegal list)

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

• Deep hand-trap and negation coverage for both going first and going second
• Synchro bosses at 3000 to 3500 ATK with several routes
• Searchers and GY recursion support recovery across turns

Weaknesses

• Illegal as built: Ash Blossom & Joyous Spring at 3 copies against an OCG limit of 2
• No Side Deck, so no post-side plan
• No recorded combos, so median output is unmeasured
• High non-engine density (18 tech and 18 hand traps in 40 cards)

Critical choke points

• Red Dragon Archfiend and Abyss/Bane require a successful Synchro; a single hand trap from the opponent can end the turn
• Ash Blossom over limit makes the list illegal until one copy is removed

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 0 counts and size rules (40-60 / 0-15 / 0-15); Ash Blossom & Joyous Spring copies_run 3 vs OCG legal limit 2 (Semi-Limited); Bystial Druiswurm and Magnamhut at 1 copy each (Limited, legal); Card stats and text for all 27 Main and 15 Extra cards; Archetype purity 18.2% exact name; archetype spread listed
• Inferred: P(>=1 core starter in 5 cards) about 0.96 (proxy from archetype core); Going-second hand-trap coverage about 0.98; Consistency, brick and interaction scores from composition and text; Red Dragon Archfiend route as the ceiling (semantic read of card text)
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13 = 50 neutral; no tournament data)
• 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 (going-first/second, matchup, brick/starter rates) exists in YGOVN Meta Power is provisional unless a dated metagame sample is supplied deck title is null in the export Side Deck is empty, so post-side behaviour cannot be scored
