Archfiend Deck #770288 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon DARK Dragon boss monsters (Red Dragon Archfiend, Red Supernova Dragon, Red Hypernova Dragon) off Resonator Tuners and Archfiend non-Tuners, then attack through a board cleared by hand traps and Synchro-based removal.; Bystial Dis Pater and The Crimson King as Synchro closers that also provide negation or removal on a stalled board.
• Turn 1 (going first): Open Soul Resonator, Crimson Gaia or Mulcharmy Fuwalos (3 copies each) to search or summon a Resonator or Archfiend starter, then Synchro Summon a boss from the Extra Deck.
• Turn 2 (going second): Hold Ash Blossom and Infinite Impermanence (both 3 copies, illegal count) to answer the opponent's first summon, then rebuild through Resonator searchers and Red Zone or Dominus Impulse-style interaction.
• Recovery: Recover through searchers (Synkron Resonator, Vision Resonator, Resonator Call, Crimson Gaia) and GY-recursion from Soul Resonator and Crimson Resonator.
• After siding: Not evaluable: the deck runs zero Side Deck cards, so there is no post-side plan.

Why it scores here

This list is Illegal for OCG: Ash Blossom & Joyous Spring and Dominus Impulse are each run three times against a Semi-Limited cap of two, so it receives no normal Final Contextual score and is capped at 35 as a theoretical, structural-only read. Structurally the deck has a real engine: the 14 Resonator and Archfiend starters and searchers give about 0.90 probability of at least one core-group card in the opening five (Inferred), and the 15 Synchro Extra Deck slots reach four 3000+ ATK bosses. Its interaction is dense (9 negation-text, 11 removal-text and 6 hand-trap cards), which earns the going-second and end-board dimensions, while the 40-card main with 24 distinct cards and an exact-archetype purity of only 14.5% costs efficiency. No combos, guides or tournament data exist, so the combo ceiling and median are text-only inferences with low weight, and the empty Side Deck and absent meta sample hold the adaptability and matchup dimensions down. The score reflects consistency, interaction and closing power on the system; it does not reflect the popularity of the Archfiend archetype (usage data confirms the list is real, not strong) and was not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52.6, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy limit (-16). Final formula: Illegal cap: 0.80*Structural (52.6) + 0.20*TournamentReliability (45) = 51.1, then modifiers -16 = 35.1, capped to 35; theoretical/structural-only, Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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

• Four Synchro bosses at 3000 to 4500 ATK with direct text
• Dense negation and removal text (9 negation, 11 removal) plus 6 hand traps
• Strong starter and searcher density (about 0.90 for the core group)
• Full 15-card Synchro Extra Deck with no empty slots

Weaknesses

• Illegal copy count on two Semi-Limited cards
• Loosely coherent main deck (14.5% exact-archetype purity, 24 distinct cards)
• Zero Side Deck cards, so no post-side plan
• No combo, guide or tournament data to confirm the median

Critical choke points

• Synchro Summon requires a DARK Tuner plus non-Tuner material, so losing the Tuner to a hand trap or board wipe stops the boss line
• Three-copy Ash Blossom and Dominus Impulse are illegal as built and must drop to two copies before the list can be scored normally

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom & Joyous Spring and Dominus Impulse at 3 copies vs OCG Semi-Limited limit of 2; Main 40 and Extra 15 are within OCG size rules; Side is 0 (0 to 15 allowed); Card text and stats for all 40+15 cards; 15 Synchro Extra Deck cards; Usage stats: 6 of 12 core archetype cards present (50%)
• Observed: No recorded combo boards for this deck (combos_evidence total 0)
• Inferred: Core-group opening probability about 0.90 and searcher-group about 0.92 (hypergeometric); Going-second hand-trap availability about 0.65; Negation and removal density read from card text; Combo ceiling and median are text-only inferences
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link or meta-share data)
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry exists in YGOVN (going-first, going-second, matchup, brick and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
