Archfiend Deck #772645 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Synchro and Link boss monsters with large ATK (Chaos Angel 3500, Bystial Dis Pater 3500, Red Dragon Archfiend 3000, Scarred Dragon Archfiend 3000), reached through Dragon-based Synchro and Link summons (Inferred from card text).; Chaos Emperor and Red-Eyes Black Fullmetal Dragon as high-ATK finishers if the Dragon engine comes online (Inferred).
• Turn 1 (going first): Open with searchers (Starliege Seyfert, Bystial Saronir, Dragunity-adjacent Dragon Ravine, Black Dragon Collapserpent) toward a Dragon Synchro or Link line; keep Ash Blossom and Effect Veiler up as the protection layer (Inferred).
• Turn 2 (going second): Hold hand traps (Ash Blossom, Effect Veiler, Droll & Lock Bird, Ghost Ogre & Snow Rabbit, Nibiru) to answer the opponent's first summon, then rebuild through Bystial recursion (Inferred).
• Recovery: Recover from the GY through Bystial Saronir, Bystial Druiswurm and Bystial Magnamhut banish-summons, Branded Regained draws and Red-Eyes searches (Inferred).
• After siding: No side deck is registered, so there is no post-side plan; the build cannot adapt between games in a best-of-3 (Verified by list).

Why it scores here

This list would be a Midrange Dragon/Archfiend shell that reliably opens searchers (P(at least one searcher text card in a 5-card hand) ≈ 0.86) and carries 11 hand traps plus 12 negation-text cards, which gives it real interaction on both going-first and going-second. Its ceiling and floor cannot be measured because no recorded boards exist, so combo conversion is an Inferred semantic read of the Synchro/Link bosses and Bystial recursion. The score is held down by the structure, not by the card quality: 19 distinct archetype labels share 36 distinct main-deck names (exact-name purity 2.9%), three cards are over their OCG copy limit, and the side deck is empty. The Illegal status caps the Final Contextual score at 30, so this is a theoretical, structural-only read. Popularity did not earn points: the archetype core is 2 of 13 usage-stat cards present, and card scores were not averaged into the deck result.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary, weights not blended. Structural ≈ 50, Going First ≈ 45, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Banlist exposure (-4); Engine conflicts (-3); No side deck (-3). Final formula: Illegal cap: uncapped formula 0.80*Structural(50) + 0.20*TournamentReliability(42) + modifiers(-10) ≈ 39, capped to 30 per rubric Step 2; Meta provisional (null); theoretical/structural-only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.86 · 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 searcher count (17) makes the opening hand reliably find a starter
• 11 hand traps and 12 negation-text cards give layered interaction on both turns
• Synchro and Link boss options give a high-ATK closing route

Weaknesses

• Legality: 2 cards are over their copy limit, so the list cannot be played as built
• Engine fragmentation: 19 archetype labels and 2.9% exact-name purity
• Empty side deck leaves no post-side plan for best-of-3
• No recorded combos or win data to confirm conversion

Critical choke points

• Ash Blossom and Effect Veiler as the only hand-trap protection on turn 1
• Bystial banish-summon chain depends on LIGHT/DARK monsters in either GY
• Searcher hits are needed to find the Synchro/Link route; a missed searcher leaves a brick

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 within OCG size rules; Ash Blossom & Joyous Spring at 3 copies (limit 2) and The Bystial Lubellion at 3 copies (limit 1) are over the copy limit; Side deck is empty; Searcher-text count 17; hand-trap count 11; negation-text count 12
• Inferred: Core engine accessibility ≈ 0.86 for a searcher in 5 cards (hypergeometric); Going-second hand-trap coverage ≈ 0.76; Synchro/Link boss routes as the primary win condition (text read); Brick risk from archetype-fragmented singletons
• Provisional: Meta and format fit (no dated sample; tournament_context unavailable); Matchup coverage (no matchup data)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown No side deck registered, so side adaptability cannot be measured Meta Power is Provisional without a dated metagame sample
