Fiendsmith Deck #747345 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 24/100 (±6 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: tcg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Boss monsters from the Light and Darkness Ritual / Lightsworn / Fiendsmith lines (Black Chaos, Black Luster Soldier, Chaos End Ruler, Magician of Dark Chaos - Black Chaos) once a Ritual or Fusion starter lands; the boss suites are present in the list but no recorded board confirms the line.; Fiendsmith's Lacrima and Fiendsmith's Requiem value engines (Fusion/Link pressure), which are only partly supported in this list (1 Fiendsmith Engraver, 1 Lacrima, 1 Tract, 6 exact-name Fiendsmith copies).
• Turn 1 (going first): Search and summon a starter from Charge of the Light Brigade / Fiendsmith Engraver / Light and Darkness Ritual, then convert into a Ritual boss; the Forbidden Red Reboot and Baronne de Fleur cards are not legal and cannot be part of the plan.
• Turn 2 (going second): No side deck, so there is no sided answer; the going-second plan relies on Evenly Matched, Heat Wave and Griffoh-style disruption, all unverified in combo evidence.
• Recovery: Recursion through Lightsworn Dragonling, Lacrima the Crimson Tears, Skull Archfiend of Chaos and Mind Shuffle is the only textual recovery route; none is confirmed by recorded boards.
• After siding: Not evaluable: the deck has zero Side Deck cards and the best-of-3 context is absent.

Why it scores here

This list is Illegal in TCG because six copies of Forbidden cards (Red Reboot, Borreload Savage Dragon, Dugares, Saryuja Skull Dread, Baronne de Fleur, Curious) are included, so it receives only a structural read capped low and not a normal Final Contextual score. Its consistency is weak: only 2 of 25 archetype-core cards are present (8%), and 64 of 70 main/extra copies are off the exact Fiendsmith name, so the engine is a loose mix of Lightsworn, Light and Darkness Ritual, Fiendsmith and Horus pieces rather than one coherent plan. Interaction density is reasonable on paper (6 negation and 22 removal text hits), and the boss suites give a real ceiling, but no recorded boards exist to confirm either conversion or median output. Archetype popularity and the usage-stat list did not earn points; the score came from the system's structure (starter access, redundancy, interaction and Extra Deck coverage), not from averaging the card scores. There is no side deck, so post-side adaptability and matchup fit are scored only as provisional.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 38, Going First ≈ 35, Going Second ≈ 30, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist_exposure (-8); engine_conflicts (-4). Final formula: Illegal deck: 0.80*Structural(38) + 0.20*TournamentReliability(30) + ContextModifiers(-12) = 24, capped low as theoretical/structural-only; Meta Power provisional/null

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.81 · 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 text (15 cards) gives a high chance of finding a starter in the opening hand
• Multiple Ritual and Fusion boss routes with 3000+ ATK bodies
• Real negation and removal text coverage (6 negation, 22 removal hits)

Weaknesses

• Illegal under TCG banlist: 6 Forbidden cards included
• Low archetype coherence: 8.6% exact-name purity, 2/25 core cards present
• No side deck and no post-side plan
• No recorded combos, no tournament data, no win-rate telemetry

Critical choke points

• Any starter that depends on King's Sarcophagus or the Light and Darkness Ritual Spell
• Single Fiendsmith Engraver and single Lacrima reduce redundancy if either is dead in hand

Recommended changes

Evidence & confidence

• Verified: Legality: 6 Forbidden cards included; main 55, extra 15, side 0; Archetype purity 8.6% exact-name; 2 of 25 usage-core cards present; Copy histogram 17/10/6 across 33 distinct main cards
• Inferred: P(>=1 searcher in opening 5) ~0.81 from hypergeometric draw estimate; Interaction density from text hints (6 negation, 22 removal); Ritual/Fusion boss ceiling read from card text
• Provisional: Meta Power (null, no dated meta sample); Tournament reliability and format fit (no tournament link)
• Data gaps: No combos supplied, so combo floor/median/ceiling is text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick/starter rates) Meta Power is provisional unless a dated metagame sample is supplied Side deck empty, so post-side plan is unevaluable
