Archfiend Deck #765751 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 57/100 (±7 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo, Toolbox
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro Summon Red Dragon Archfiend (or Bane, Nova, Supernova) off a Resonator-tuner board and attack through the field; Chain Resonator and Synkron Resonator recursion to re-stack Resonator tuners and rebuild Synchro access
• Turn 1 (going first): Search or Special Summon a Fiend tuner (Soul Resonator, Vision Resonator, Synkron Resonator), then Synchro into a Red Dragon Archfiend or Power Vice Dragon line while holding Ash Blossom and Droll as hand interaction
• Turn 2 (going second): Hold Ash Blossom, Droll and Maxx C to answer the opponent's first summons, then rebuild the Resonator tuner chain through Crimson Gaia and Resonator Call
• Recovery: Recover tuners from the Graveyard via Synkron Resonator and Vision Resonator's Graveyard effect, then re-enter a Red Dragon Archfiend
• After siding: No side deck is registered, so no post-side plan can be evaluated; the deck is effectively fixed for all three games

Why it scores here

The deck reliably opens a playable line most of the time: the searcher text is dense (p of at least one searcher in a 5-card opening hand is about 0.96), and the Resonator tuners give several independent entry points into Synchro Summons. Its interaction is the strongest part of the list, with seven hand traps (two Ash Blossom, two Droll and Lock Bird, Maxx C, Nibiru, Ghost Belle) plus removal and negation text, which supports going second. Its closing power comes from single-copy top-end Synchros such as Red Supernova Dragon and Hot Red Dragon Archfiend Bane, and from the three Red Dragon Archfiend-family attackers. No recorded boards exist, so the combo ceiling and median are inferred from card text rather than measured; popularity and the single guide did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers = 0.80*59.08 + 0.20*54.3 - 1 ≈ 57

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

• Seven hand traps and about 13 interaction-text cards give layered answers
• Dense searcher text (18 cards) keeps opening hands functional
• Single-copy top-end Synchros (Red Supernova Dragon, Bane, Nova) give closing power
• Full 15-card Extra Deck used with no dead slots

Weaknesses

• No side deck at all, so no adaptation across best-of-3
• Exact archetype purity only 20 percent; the list relies on Resonator and generic cards
• Fifteen tuners and many 0-level spells raise brick risk
• No recorded combo boards, so the ceiling and median are unverified

Critical choke points

• Reaching a Tuner-plus-Synchro board depends on one or two Fiend tuners in hand
• Floodgate or Shifter-style cards named in the guide would hit the Archfiend engine hard

Recommended changes

Evidence & confidence

• Verified: Legal status, 40/15/0 sizing, Limited and Semi-Limited copy counts; Card stats and role tags from the evidence pack; Searcher-text count of 18 and hand-trap count of 7
• Observed: Usage stats: Maxx C 70 percent and Ghost Belle 60 percent inclusion
• Inferred: Starter and brick probabilities from hypergeometric draws; Combo ceiling and median from card text, since no boards exist; Interaction quality and going-second split read from text
• Provisional: Meta power (no dated sample); Matchup and format fit (no tournament link)
• 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 and going-second splits are Inferred Meta Power is Provisional unless a dated metagame sample is supplied no side deck registered; post-side performance unknowable
