Archfiend Deck #771820 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±6 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon Red Dragon Archfiend family and high-ATK Synchros (Red Supernova Dragon, Hot Red Dragon Archfiend Bane, Bystial Dis Pater) to attack through a negate-protected board; Crimson Gaia and Resonator recursion chains into repeated Synchro boards
• Turn 1 (going first): Open a Resonator Tuner or Crimson Gaia starter, search a second Tuner, Synchro Summon into a 3000-ATK boss, and hold Ash Blossom or Gravity Collapse for the opponent's first response
• Turn 2 (going second): Use Ash Blossom, Infinite Impermanence, Ghost Belle, or Dominus Impulse on the opponent's first Summon or search, then rebuild with Soul Resonator or Vision Resonator from hand
• Recovery: Resonator and Archfiend monsters recur from the GY through Synkron Resonator, Vision Resonator, Soul Resonator, and Crimson Call
• After siding: No Side Deck is registered, so there is no post-side plan. Not scored beyond the D12 floor

Why it scores here

This list is a 55-card OCG main with 18 searchers and 15 Synchros, so the engine is accessible on paper: Resonator Tuners and Crimson Gaia give several independent T1 starters, and P(at least one searcher in a 5-card hand) is about 0.87 (Inferred). Its interaction density is high, with 21 negation-text cards and 12 hand traps, which lifts endboard quality. The deck loses points for bloat (27 distinct main cards, many Level 0 Spells and Traps with conditional value), a brick-prone 55-card main, and a zero-card Side Deck that leaves no post-game adaptation. Popularity and archetype usage do not add points: the list runs only 9 of 70 cards with the exact 'Archfiend' name, and no combos, guides, or tournament data exist to confirm a median or ceiling. Structural power was computed from dimension scores on a Midrange profile, not from averaging card scores. The result is capped low because two cards exceed their OCG copy limit, so the score is theoretical only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-6); no Side Deck (-4). Final formula: No reliable metagame: 0.80*Structural(57.9) + 0.20*TournamentReliability(48) = 55.9; modifiers -10 gives 45.9; capped at 35 because the deck is Illegal (copy-limit violations), so the score is theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · 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 negate and hand-trap suite (21 negation-text cards, 12 hand traps)
• Wide starter access with 18 searchers and multiple three-copy Tuners
• Extra Deck of 15 Synchros with several 3000+ ATK bosses and a recursion engine

Weaknesses

• Illegal in OCG: Ash Blossom and Dominus Impulse exceed the Semi-Limited copy limit
• No Side Deck (0 cards)
• Bloated 55-card main with 16 Level 0 Spells and Traps
• Exact archetype purity 12.9%, so the engine is split across sub-archetypes

Critical choke points

• Synchro Summon requires a live Tuner on the field, so a single Tuner removal or negate can stall the turn
• Most negates need specific resources (a card to discard, a Trap in the GY, or a Synchro face-up)
• Over-limit cards mean the list cannot be played as built in OCG until corrected

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 are within OCG size rules; Ash Blossom and Dominus Impulse exceed the OCG copy limit (3 run, 2 legal); Five Limited cards run at 1 copy, which is legal; Extra Deck has 15 Synchros across 12 distinct cards
• Inferred: At least one starter in a 5-card hand is about 0.85 for the Resonator and searcher package; Full-brick risk is above average for a 55-card main with many reactive spells; Negate and hand-trap density gives a high interaction score
• Provisional: Meta Power is null and Matchup Format Fit is neutral because no dated meta sample is supplied
• Data gaps: no combos supplied, so combo floor, median, and ceiling are text-only no tournament link, so archetype meta-share and per-pilot record are absent no win-rate telemetry no Side Deck, so post-side scoring is at the floor deck title is null
