Fiendsmith Deck #769828 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Fusion Summon a high-ATK Extra Deck monster (Hyperinvoked Aeon, Invoked Oceanus, Tearlaments Kaleido-Heart, Fiendsmith's Lacrima) from Tearlaments, Invoked and Fiendsmith engines; Link and Xyz pressure (Fiendsmith's Sequence, Zenna's Deceiving Doll Maidens, Evilswarm Exciton Knight) with Droll and Maxx C as interaction
• Turn 1 (going first): Open a starter (Tearlaments Scream, Invocation Sword, Aleister or Reinoheart), search an Aleister or Tearlaments follow-up, and build a Fusion or Link board while holding Maxx C or Droll for the opponent's first summon
• Turn 2 (going second): Use Maxx C, Droll and Lock Bird, Tearlaments Sulliek or Metanoise to slow the opponent's board, then convert the remaining hand into a Fusion Summon from the Extra Deck
• Recovery: Recover through graveyard effects (Lacrima, Fiendsmith Engraver, Foolish Burial Goods, Heartbeat) to re-search Tearlaments traps and Fiendsmith spells and rebuild a Fusion board from the GY
• After siding: Not applicable: the deck runs no Side Deck, so there is no post-side plan

Why it scores here

The deck reliably opens a functional starter: four starter types (Scream, Invocation Sword, Aleister, Reinoheart) each run three copies, giving roughly 0.85 for at least one of them in a five-card opening hand (Inferred hypergeometric estimate). Conversion is the weak point: no recorded boards exist, the ceiling rests on text reads of Fusion routes, and Rulkallos cannot be made because its Kitkallos material is absent. Interaction is the strongest area, with Maxx C, Droll and Lock Bird, Tearlaments Sulliek, Metanoise and Trivikarma giving breadth across both turn orders. The deck has no Side Deck and runs three overlapping engines (Tearlaments, Invoked/Aleister, Fiendsmith), which lowers consistency and adaptability. Popularity did not earn points: the Fiendsmith archetype share is not in the export, and exact-name purity is only 10.9 percent. The score comes from the deck as a system, not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 58, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist_exposure (-3); engine_conflicts (-2); no_side_deck (-1). Final formula: 0.80*Structural(56.2) + 0.20*TournamentReliability(50) + ContextModifiers(-6) = 49; Meta Provisional (no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.85 · 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

• Four starter types with three copies each on the four main starters
• Interaction breadth: Maxx C, Droll and Lock Bird, Sulliek, Metanoise, Trivikarma, Keldo and Mudora
• Multiple Fusion routes with high-ATK closers (Hyperinvoked Aeon 3800, Invoked Oceanus 3000, Kaleido-Heart 3000)
• Recursion through Lacrima, Engraver and Heartbeat keeps resources regenerating

Weaknesses

• No Side Deck, so zero post-side adaptation in a best-of-three format
• Three overlapping engines reduce starter density for each one
• Rulkallos is unreachable without Kitkallos
• 14 Limited cards limit redundancy in the engine

Critical choke points

• Aleister the Reminiscent (Invoked Fusion material and the only Spellcaster-based Fusion route) if it is blocked or banished
• Singleton Fiendsmith engine pieces (Tract, Engraver, Lacrima) for Fiendsmith lines

Recommended changes

Evidence & confidence

• Verified: Legal status: 40 main, 15 extra, 0 side; all banlist copy limits respected; Card texts, stats and banlist tokens as listed in the evidence export; Archetype spread: Tearlaments 13, Fiendsmith 6, Invoked 4, Aleister 3 copies; exact-name purity 10.9 percent
• Inferred: Starter union probability 0.85 in a 5-card hand (hypergeometric); Consistency, brick risk and engine conflicts from composition and card text; Combo ceiling and floor from text-only route reads, since no boards were recorded; Interaction density from removal and negation text
• Provisional: Meta power (null; no dated metagame sample); Matchup and format fit (D13 placeholder 50; no tournament link)
• 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 for going-first/second, matchups, brick or starter rates usage_statistics flags Fiendsmith's Requiem, Fiendsmith's Sequence, S:P Little Knight and Fiendsmith's Lacrima as not in this deck, yet the card list places all four in the Extra Deck; core_present_pct (40) is understated and the stats likely ignore the extra zone Meta Power is Provisional unless a dated metagame sample is supplied
