Archfiend Deck #771923 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, 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 beatdown from Red Dragon Archfiend and its Archfiend-named Synchro variants (Scarlight, Scarred, Hot Red Dragon Archfiend Abyss) backed by Chaos Angel and Bystial Dis Pater; Mulcharmy draw pressure and Bystial Lubellion / Magnamhut Dragon Synchro beats
• Turn 1 (going first): Open a Tuner (Soul Resonator, Vision Resonator, Ghost Ogre) plus Bone Archfiend or Crimson Gaia, then Synchro into a Red Dragon Archfiend while holding Ash Blossom or Infinite Impermanence for the opponent's response
• Turn 2 (going second): Hold a hand trap (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Infinite Impermanence) to stop the opponent's first board, then rebuild through Crimson Gaia or Crimson Call
• Recovery: Resonator monsters return from the GY via Synkron Resonator and Vision Resonator, and Mulcharmy draws refill the hand
• After siding: Not evaluable: the deck has no Side Deck (0 cards), so there is no post-side plan

Why it scores here

The deck reliably opens an engine: the archetype core group (23 copies) is at least one card in the opening 5 about 94% of the time (hypergeometric, Inferred), and Tuners such as Soul Resonator and Vision Resonator give a reasonable path to a Synchro into Red Dragon Archfiend or its variants. Interaction is dense (10 hand traps and about 15 negation-text cards plus Solemn Judgment, Harpie's Feather Duster and Lightning Storm), which lifts the interaction, going-second and closing dimensions. Its weaknesses are the loose archetype purity (about 11% exact-name, with 62 off-archetype copies), 12 single-copy slots, and the lack of a Side Deck, which pulls down the consistency, efficiency and side-adaptability reads. The score comes from consistency, interaction and closing power on the system, not from Archfiend's popularity and not from averaging individual card scores. The list is Illegal (Ash Blossom and Dominus Impulse run 3 copies against a limit of 2), so the score is capped at a structural-only read of 30.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 62, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Illegal copy-limit violation (-12); No Side Deck (0). Final formula: Unconstrained: 0.80*60 + 0.20*52 - 12 (legality modifier) = 46; capped at 30 because the deck is Illegal (structural-only, theoretical). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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 interaction: 10 hand traps plus negate and removal text across the list
• Strong Synchro closers: Chaos Angel, Bystial Dis Pater, Hot Red Dragon Archfiend Abyss
• Archetype core is accessible in the opening hand (about 94% for at least one core card)

Weaknesses

• Illegal list: Ash Blossom and Dominus Impulse exceed the Semi-Limited copy limit
• Low archetype purity (11.4%), with many off-archetype and sub-archetype slots
• No Side Deck, so no post-side adaptation
• 12 single-copy slots and many conditional draw effects increase brick and decision risk

Critical choke points

• The opening hand needs a Tuner plus a starter; a hand without either is a brick
• Red Dragon Archfiend is the main closer, and the Synchro chain depends on Tuner access

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 (size rules OK for OCG); Ash Blossom and Dominus Impulse over Semi-Limited limit (3 copies vs 2); Limited cards run at 1 copy each, within limit; Exact-name purity 11.4%; 15 Synchro cards in Extra
• Observed: Usage stats: Crimson King, Dis Pater and Abyss are the most-used core cards not in this list
• Inferred: Archetype core opening-hand access about 0.94; Hand-trap availability going second about 0.72; Interaction density is high based on card text
• Provisional: Meta fit and matchup coverage (no dated meta sample or 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 record absent No win-rate telemetry; going-first and matchup signals are Inferred or Unknown Meta Power is Provisional Deck title is null
