Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 41 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Red Dragon Archfiend family Synchro boss (Red Dragon Archfiend, Scarred Dragon Archfiend, Hot Red Dragon Archfiend Abyss/Bane) plus Bystial Dis Pater and Red Supernova Dragon as large Extra Deck threats; Recursion of Resonator and Archfiend monsters from the GY through Synchro and GY-trigger effects (Red Rising Dragon, Synkron/Vision/Crimson Resonator, Bone Archfiend)
• Turn 1 (going first): Open a Resonator or Archfiend starter with Soul Resonator, Vision Resonator, Bone Archfiend or Resonator Call, search a Resonator or Synchro enabler, then Synchro into a Red Dragon Archfiend-family boss while holding Ash Blossom and Effect Veiler for interaction
• Turn 2 (going second): Use 8 hand traps (Ash Blossom, Effect Veiler, Infinite Impermanence, Maxx C, Nibiru, and others) to answer the opponent's first board, then rebuild through GY-trigger Resonator recursion into a Synchro boss
• Recovery: Resonator monsters sent to the GY can be added or Special Summoned again (Synkron Resonator, Red Rising Dragon, Crimson Resonator text), and 17 searcher-text cards support rebuilding
• After siding: Not applicable: the deck runs 0 Side Deck cards and the Master Duel size rule allows 0, so no post-side plan is evidenced

Why it scores here

Scored as a system, not as an average of card scores. The Resonator and Archfiend starters are redundant: three copies each of Soul Resonator, Bone Archfiend, Resonator Call and Ash Blossom give roughly a one-in-three chance of at least one of each in a 5-card opening, and the 17 searcher-text cards push searcher access to about 94% in hand (Inferred, hypergeometric). Interaction is the strongest area: 8 hand traps and 8 negation-text cards give about a 75% chance of at least one hand trap when going second (Inferred). The Extra Deck is full of high-ATK Synchro bosses that give real closing power, but no combo evidence was supplied, so conversion and median output are text-only estimates. Popularity did not earn points: the archetype core is present in only 3 of 25 usage-stat cards (12%). The deck is Illegal because Called by the Grave is Forbidden and run at one copy, so the score is capped and is structural-only.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 52, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: Banlist exposure (-3); Engine coherence (-2). Final formula: No reliable metagame: 0.80*Structural(56) + 0.20*TournamentReliability(48) = 54.4; plus context modifiers (-5) = 49.4; Illegal cap applied, final score 35 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.33 · 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

• Three copies each of multiple Resonator and Archfiend starters give consistent access
• Dense interaction: 8 hand traps and 8 negation-text cards, strong on going second
• High-ATK Extra Deck closers (Red Dragon Archfiend family, Bystial Dis Pater, Red Supernova Dragon)
• Multiple searcher effects (17 searcher-text cards) support rebuilding

Weaknesses

• Illegal list: Called by the Grave is Forbidden and run at 1 copy
• Four Limited cards exposed to banlist changes
• Off-archetype spread (56 copies outside the exact archetype) reduces engine coherence
• No Side Deck, so no post-side plan is evidenced
• No combo or tournament data to confirm conversion or matchup performance

Critical choke points

• Illegal copy of Called by the Grave must be removed before the deck can be scored normally
• Starter access depends on a few 3-copy Resonator and Archfiend cards, with P(>=1 in 5 cards) about 0.33

Recommended changes

Evidence & confidence

• Verified: Legality: Called by the Grave is Forbidden with 1 copy run; all other restricted cards are within limits; Main Deck 41 cards and Extra Deck 15 cards; both within the Master Duel size rules; Card text and stats for the listed cards, from the evidence excerpts
• Inferred: Starter and searcher probabilities from hypergeometric draws; Hand-trap access when going second; Interaction quality from negation and removal text
• Provisional: Meta power and matchup fit (no dated metagame sample); Side deck adaptability (no Side Deck in the list)
• 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 exists in YGOVN for this deck Meta power is provisional: no dated metagame sample Not verified: Scarred Dragon Archfiend and Scarlight Red Dragon Archfiend take the name Red Dragon Archfiend on the field and in the GY, and the evidence checks copy limits by printed name only, so the effective-name count is unchecked
