Archfiend Deck #771675 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Midrange, Synchro Engine
• Format: ocg

Legality

Main 43 / 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-named monsters (Red Dragon Archfiend, Scarred/Scarlight, Red Supernova, Tyrant Red Dragon Archfiend) to attack or destroy the opponent's board; Hot Red Dragon Archfiend Abyss / Bane and Red Nova Dragon for negation and board control after Synchro Summon
• Turn 1 (going first): Open with Resonator Call / Crimson Gaia / Soul Resonator style searches to assemble a Fiend Tuner plus non-Tuner, then Synchro into a 3000+ ATK Dragon. Consistency is theoretical because no combo boards were supplied.
• Turn 2 (going second): Hold Ash Blossom (over limit), Infinite Impermanence, Droll & Lock Bird and Power Vice Dragon as hand interaction to protect the first Synchro line. Stated as Inferred, not observed.
• Recovery: Recursion through Synkron Resonator, Vision Resonator and Crimson Call to return Resonators and Red Dragon Archfiend from the GY, which is a structural read from card text only.
• After siding: No side deck is built, so there is no post-side plan. Adding a side is needed before any best-of-3 read is meaningful.

Why it scores here

The deck is scored as a system: Resonator-based searching and Fiend Tuner access give a high probability of having a starter (about 0.94 for searcher text in a 5-card hand, Inferred), and the Red Dragon Archfiend Synchro lines give a high closing ceiling. Floor and median output cannot be measured because no combo boards were supplied, so those scores stay near the midpoint. Interaction is decent, with 7 hand traps and roughly 0.68 odds of at least one going second, but the Ash Blossom over-limit copy makes the list illegal. Archetype popularity (Archfiend usage 53-74% for the core cards) confirms the list is real, but it did not add points, and card scores were not averaged. The empty side deck removes any post-side plan. The deck is capped as theoretical/structural only because it is illegal.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(56) + 0.20*TournamentReliability(45) = 53.8, then -12 illegal-list modifier, then capped at 30 because the deck is Illegal (theoretical/structural only)

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

• Very high searcher and Resonator density gives a reliable opening-hand starter (Inferred)
• Synchro closing power from Red Supernova Dragon (4000 ATK) and Tyrant Red Dragon Archfiend (3500 ATK)
• Hand-trap suite of 7 cards with good going-second coverage (Inferred)

Weaknesses

• Illegal list: Ash Blossom over the Semi-Limited copy limit
• Empty side deck; no post-side plan
• Low archetype purity (20.7% exact-name) with many off-archetype cards, which weakens engine coherence
• No combo data, so floor and median output are unknown

Critical choke points

• Single Red Dragon Archfiend Synchro route depends on Fiend Tuner access
• Ash Blossom over-limit copy must be cut before the list can be played

Recommended changes

Evidence & confidence

• Verified: Deck is illegal: Ash Blossom & Joyous Spring 3 copies vs Semi-Limited limit 2; Main 43 and Extra 15 are within size rules for OCG; Card stats and text from the evidence pack
• Observed: Archetype usage stats: core cards at 51-74% inclusion (Core usage data); Copy histogram and composition counts
• Inferred: Starter reliability ≈ 0.94 from the searcher-text proxy; Hand-trap going-second coverage ≈ 0.68; Synchro closing ceiling from card text
• Provisional: Meta Power (no dated sample); Matchup fit
• 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/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No side deck supplied, so post-side is unevaluated
