Archfiend Deck #769940 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 42/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Control
• Format: ocg

Legality

Main 57 / 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 and its Synchro bosses (Hot Red Dragon Archfiend Abyss, Red Supernova Dragon, Dragocytos) to attack through the board; Crimson Blade Dragon and The Crimson King as backup Synchro boards, plus Bystial recursion/banish for board presence
• Turn 1 (going first): Turn 1 Normal Summon a Tuner starter (Soul Resonator, Power Vice Dragon or Bone Archfiend), search a Resonator or Red Dragon Archfiend route via Crimson Gaia/Resonator Call, then Synchro Summon a boss on turn 2
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Droll & Lock Bird, Infinite Impermanence and Ghost Ogre to answer the opponent's first board, then Synchro Summon through the remaining monsters and negate with Dominus Impulse/Solemn Judgment when needed
• Recovery: Recover through Mulcharmy draw effects, Synkron/Vision Resonator GY recursion, Crimson Call GY recovery and the searcher line in Synchro Monsters
• After siding: No Side Deck is registered, so no post-side plan can be evaluated; the deck is theoretical until it is legal and gets a side list

Why it scores here

This is a theoretical, structural-only score because the list is Illegal: Ash Blossom & Joyous Spring is run 3 copies against a Semi-Limited limit of 2, and Triple Tactics Talent is a Forbidden card run once. The deck reliably opens a Tuner starter (P(>=1 searcher in a 5-card hand) is about 0.82 and roughly 0.20 of hands have no archetype core card), then converts into Synchro bosses from its 15-card Extra Deck, with Red Dragon Archfiend and its Synchro bosses providing closing power. Interaction is dense (15 negation-text and 22 removal-text cards, 10 hand traps), which earns the going-second and endboard scores, while the 9.7% exact-archetype purity and no Side Deck keep the consistency and post-side scores modest. The score was built from the system's consistency, median output and interaction, not from averaging card scores, and the Archfiend popularity (usage data is present) was not credited as power.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; no secondary blend applied (illegal list, theoretical only). Structural ≈ 56, Going First ≈ 54, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal list cap (banlist and copy-limit violations) (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); Illegal list, so the final score is capped low and labelled theoretical: 0.8*56 + 0.2*45 = 53.8, then -12 illegal-list modifier = 42

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ — · full-brick estimate ≈ 0.2 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and negation suite (10 hand traps, 15 negation-text cards)
• Strong Synchro bosses in the Extra Deck, including 3000-4000 ATK monsters
• 16 searcher-text cards support consistent access to starters

Weaknesses

• Illegal copy limit and a Forbidden card
• Very low exact-archetype purity (9.7%) with 65 off-archetype copies
• No Side Deck, so post-side adaptability is unknown

Critical choke points

• Red Dragon Archfiend and Synchro boss lines depend on Tuner starters, so Ash Blossom or Ghost Belle answering the first Tuner Summon can stall the turn
• Fixing the banlist violations removes the Forbidden card and one Ash Blossom copy

Recommended changes

Evidence & confidence

• Verified: Main 57 and Extra 15 are within OCG size rules; Ash Blossom & Joyous Spring 3 copies vs limit 2 (Semi-Limited); Triple Tactics Talent Forbidden, run 1 copy; Side Deck is empty
• Observed: Usage stats: 12 core cards listed, 7 present in this list
• Inferred: P(>=1 starter in 5) about 0.82; Full-brick estimate about 0.20; Interaction density high from card text; Going-second hand-trap coverage about 0.70
• Provisional: Meta Power is null: no dated metagame sample; D13 matchup fit is provisional
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so meta-share and pilot match record are absent No win-rate telemetry, so going-first/second and matchup results are unknown No Side Deck registered Meta Power provisional unless a dated metagame sample is supplied
