Archfiend Deck #774945 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 58/100 (±7 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Synchro Summon Red Dragon Archfiend or a Hot Red / Dis Pater / Red Nova boss, supported by Resonator tuners and Archfiend searchers; Crimson Gaia and Crimson Call search Red Dragon Archfiend and its Synchro support, letting the Extra Deck boss return after removal
• Turn 1 (going first): Search a Resonator tuner or Archfiend starter with Resonator Call, Crimson Gaia or Vision Resonator, then Synchro into a 3000+ ATK boss while holding Ash Blossom and Droll for the opponent's first response
• Turn 2 (going second): Hold Ash Blossom, Maxx C, Droll and Infinite Impermanence in hand to stop the opponent's first board, then Synchro through the remaining interaction (Nibiru and Maxx C punish 5+ summons)
• Recovery: Resonator and Mulcharmy draws plus Synkron and Vision Resonator GY recursion rebuild a tuner and a starter after one interruption
• After siding: No side deck is registered, so there is no post-side plan to evaluate; any sideboarding is unscored

Why it scores here

The deck reliably opens a Resonator or Archfiend starter: the archetype core is at least one copy in the opening 5 about 93% of the time, and 18 searcher effects in the Main Deck support it (Inferred, from hypergeometric estimates and card text). Its Synchro engine has nine Resonator tuners and two Red Dragon Archfiend copies, so it can convert into 3000 to 4500 ATK bosses, and the ceiling is high on paper. The deck survives interruption through ten hand traps, sixteen to seventeen removal or negation text effects, and GY recursion, while its floor is held down by conditional starters (Mulcharmy and Lightning Storm need an empty or no-face-up field, which conflicts with Synchro boards). Popularity and archetype usage stats confirm the list is a real, accessible build, but they earned no points. The score comes from consistency, interaction and bosses on the system, and card scores were not averaged; the empty side deck and the Limited hand traps pull it down.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 64, Going First ≈ 66, Going Second ≈ 68, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: banlist exposure (-2); engine conflict (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; 0.80*63.6 + 0.20*52 = 61.3, minus 3 = 58)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Core engine is accessible on the opening hand (about 93% for at least one core card)
• Deep Synchro bosses from 3000 to 4500 ATK with Resonator tuner density
• Ten hand traps plus broad removal and negation text give layered interaction on both turns
• Recursion (Synkron, Vision Resonator, Mulcharmy draw) helps rebuild after an interruption

Weaknesses

• No side deck, so no post-side adaptation
• Limited-status hand traps and Maxx C leave few copies to rebuild interaction after a ban
• Conditional starters (Mulcharmy, Lightning Storm, Fiend Piece Golem) risk dead cards
• Only one-copy Synchro bosses (Crimson Blade, Hot Red, Dis Pater) sit under the 3-copy starter count

Critical choke points

• Red Dragon Archfiend and the Resonator tuner line: a single removal or hand-trap window on the tuner can stall the whole Synchro engine
• Ash Blossom and Droll are 2-copy and 1-copy stoppers, so the opponent's first disruption often decides going-first lines

Recommended changes

Evidence & confidence

• Verified: Legality: Legal in OCG; 55 Main, 15 Extra, 0 Side; all Limited and Semi-Limited copy counts within limits; Card text and stats for every listed card (evidence cards[] block); Archetype usage: The Crimson King 71.6%, Bystial Dis Pater 69.3%, Droll and Lock Bird 68.2%, Soul Resonator and Power Vice Dragon 62.5 to 63.6%
• Inferred: Opening-hand consistency: 0.93 at least one core card (hypergeometric); Interaction density and going-second hand-trap coverage from card text; Synchro engine conversion ceiling from boss ATK and Resonator tuner density
• Provisional: Meta Power (no dated metagame sample); D13 matchup fit and tournament reliability (no tournament link)
• Data gaps: No recorded combos: 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/second, matchup or brick/starter rates Deck title is null and the side deck is empty; post-side play is unscored Meta Power is Provisional unless a dated metagame sample is supplied
