Fiendsmith Deck #754236 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Toolbox, Fusion/Link/Xyz mechanic tags
• Format: tcg

Legality

Main 58 / Extra 15 / Side 0 — status: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Special Summon Sacred Beast boss monsters (Infinity of the Sacred Beasts - Raviel, Calamity of the Sacred Beasts - Hamon, Inferno of the Sacred Beasts - Uria) with Phantasm Sacred Beasts engine spells, then attack or pressure with 4000-ATK bodies; The Chaotic Phantasmal Sacred Beasts (5000 ATK Fusion) when its three Level 10 materials are available; Fiendsmith's Lacrima ATK debuff as a supporting closer
• Turn 1 (going first): Open a Sacred Beast starter (Sacred Beasts Thunderclap, Sacred Beasts Released, Martyr of the Sacred Beasts, Summoner of the Sacred Beasts) and search or Special Summon a Level 10 Sacred Beast; protect the line with Ash Blossom and Ghost Belle
• Turn 2 (going second): Use the six-card hand to present hand traps (Ash Blossom, Ghost Belle, D.D. Crow, Droll and Lock Bird, Nibiru) against the opponent's Summons, then rebuild through Sacred Beast recursion
• Recovery: Recycle Sacred Beasts Released and Martyr of the Sacred Beasts from the GY, and Fallen Paradise of the Sacred Beasts as a repeatable discard-to-Special-Summon engine
• After siding: Not evaluable: the deck runs 0 side cards, so there is no post-side plan

Why it scores here

The deck is Illegal in TCG as submitted: Ash Blossom & Joyous Spring is run three times against a Semi-Limited limit of two, and Reprodocus and Protectcode Talker are Forbidden. The rubric caps such a list, so the score of 30 is a theoretical, structural-only read and not a normal Final Contextual score. The structural read favours the Sacred Beast Phantasm engine: about a 24% chance per three-copy starter in a 5-card opening hand, a high-ceiling Level 10 boss package, and 13 hand traps that give it reasonable going-second interaction. Against that, the list is split across Phantasm, Fiendsmith, Mulcharmy and other sub-archetypes (exact Fiendsmith purity is 8.2%), it has no sideboard, and the Extra Deck carries two Forbidden cards. Popularity and usage statistics confirm that the core is real and accessible, but they earned no points on their own. No combo boards were supplied, so the floor and median are inferred from text rather than measured, and the scores were not produced by averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-12); engine_conflicts (-4); no_side_deck (-2). Final formula: Illegal cap applied: unclamped 0.80*Structural(58) + 0.20*TournamentReliability(45) + modifiers(-18) = 37, capped at 30 (theoretical/structural only; Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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

• High-ceiling Level 10 boss package (Raviel, Hamon, Uria) with a 4000-ATK body and recursion engine
• 13 hand traps give reasonable going-second interaction
• Core starters are three-of and the searcher density is high (21 cards)

Weaknesses

• Illegal as submitted: copy-limit and Forbidden card violations
• Diffuse build: only 6 exact archetype cards out of 73 non-blank slots
• No sideboard, so no post-side plan
• Extra Deck carries two Forbidden cards

Critical choke points

• Every Sacred Beast boss needs a Sacred Beast starter in hand, and most three-copy starters miss the opening hand about 76% of the time
• Losing the one Level 10 Sacred Beast to a hand trap or board-breaker stops the line

Recommended changes

Evidence & confidence

• Verified: Legality: Ash Blossom 3 vs limit 2 (Semi-Limited); Reprodocus and Protectcode Talker Forbidden; Main Deck 58 cards within 40-60; Extra Deck 15 within 0-15; Side Deck 0; Composition counts and archetype purity (8.2% exact name)
• Observed: Usage statistics confirm the Sacred Beast Phantasm core is an accessible archetype-standard build
• Inferred: Starter probabilities 0.2408 (per 3-copy card, hand 5), 0.9049 (searcher group), 0.7988 (hand traps, going second); Hand-trap and recursion resilience reads from card text; Ceiling from semantic reading of Sacred Beast Special Summon text
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link
• Data gaps: Illegal list: the legality cap applies and the score is structural-only No combos supplied, so the floor, median and ceiling are text-only inferences No tournament link: archetype meta-share and pilot match record are absent No win-rate telemetry exists, so going-first/second and matchup values are Inferred Usage statistics in_this_deck flags conflict with the card list: Fiendsmith's Requiem, Fiendsmith's Sequence, The Chaotic Phantasmal Sacred Beasts, D/D/D Wave High King Caesar, Necroquip Princess, Relinquished Anima and S:P Little Knight are listed in the Extra Deck cards but flagged in_this_deck false Meta Power is Provisional
