Unchained Deck #771303 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

• Primary strategy: Toolbox
• Secondary strategies: Stun, Tempo
• Format: ocg

Legality

Main 52 / Extra 13 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Luce the Dusk's Dark, Fiendsmith's Desirae, A Bao A Qu, Underworld Goddess) reached through Fiend-based searches and Link/Fusion summons, backed by a Fiendsmith and Unchained engine that is only partly built.; Recursive Infernity and Archfiend revival from the Graveyard after a board is cleared by the deck's removal and negation cards.
• Turn 1 (going first): Open a Fiendsmith or Unchained searcher with a 3-copy starter. The list's 3-copy Fiendsmith cards are illegal above one copy, so this line exists only on paper until the list is fixed.
• Turn 2 (going second): Use Solemn Strike, Solemn Judgment, Infernity Barrier, Evenly Matched and Forbidden Droplet to answer the opponent's first summon or activation, then rebuild through Mulcharmy draw effects and searchers.
• Recovery: Recover from the Graveyard with Infernity Launcher, This Creepy Little Punk, Archfiend Heiress and Unchained Soul Lord of Yama; the Limited-copy cards in the deck make this recovery less dependable.
• After siding: Not evaluable: the deck runs no Side Deck (Side Deck size 0), so there is no post-side plan.

Why it scores here

The score is capped low because the list is illegal: Fiendsmith Engraver and Fiendsmith's Tract are each run three times against a Limited limit of one, so no normal Final Contextual score is given. The structural read treats the deck as a system. Searchers (11 cards) have about a 71% chance of at least one in a 5-card opening hand, but the 3-copy starters only reach about 27%, so consistency rests on Fiend-type searching and not on a single engine. Interaction is dense (Solemn Strike, Solemn Judgment, Infernity Barrier, Evenly Matched, Forbidden Droplet, Harpie's Feather Duster, Droll & Lock Bird), and that interaction is the strongest part of the list. The main deck spreads across at least five sub-archetypes (exact-name purity 6.2%), which weakens engine coherence and recovery. No combos or matchup data are in the evidence, so the floor, median and ceiling are text-only inference. Popularity was not credited: the archetype usage stats show that most of the usual core cards are absent. No points came from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 48, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-4); engine conflict (-3). Final formula: Illegal cap applied (theoretical/structural-only): min(30, 0.80*Structural(48.4) + 0.20*TournamentReliability(35) + modifiers(-7)) = min(30, 38.7) = 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.27 · 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 interaction package: 3 Infernity Barrier, 3 Evenly Matched, 3 Forbidden Droplet, Solemn Strike ×2, Solemn Judgment ×1, Harpie's Feather Duster ×1
• Eleven searcher-text cards give a ~71% chance of at least one searcher in the opening hand
• High-ATK Extra Deck bosses (Luce the Dusk's Dark, Underworld Goddess of the Closed World, Fiendsmith's Desirae, A Bao A Qu)
• Fiend-type synergy: 27 Fiend-race cards support Fiend-based searches and recursion

Weaknesses

• Illegal list: two cards exceed their copy limits and must be cut before the deck can be played
• No combo data, no side deck and no tournament data, so the power read is largely inferred
• Low exact-name purity (6.2%) across at least five sub-archetypes weakens engine coherence and recovery
• Many non-monster slots (30 Level-0 cards) and Mulcharmy draw effects that are dead without cards in hand

Critical choke points

• Both 3-copy Fiendsmith cards (Engraver and Tract) are illegal above one copy, so the starter line is unplayable as built
• Limited-copy cards (Infernity Launcher, Solemn Judgment, Foolish Burial, Droll & Lock Bird, Harpie's Feather Duster, S:P Little Knight) cap how many engine and interaction pieces can be run together

Recommended changes

Evidence & confidence

• Verified: Main 52, Extra 13, Side 0; Main and Extra sizes are within the OCG size rules; Fiendsmith Engraver and Fiendsmith's Tract are each at 3 copies against a Limited limit of 1 (status Illegal); Limited-status cards run at or under their limit: Droll & Lock Bird, Foolish Burial, Harpie's Feather Duster, Infernity Launcher, S:P Little Knight, Solemn Judgment; Archetype purity 6.2%; archetype core group present 23.5%; Card text confirmed for the interaction and searcher cards in the excerpts
• Inferred: Opening-hand consistency figures (P(>=1 starter in 5) ≈ 0.27 for 3-copy starters; searcher group ≈ 0.71); Interaction density as a strength; Toolbox primary read; Going-first and going-second power estimates
• Provisional: Meta Power (null, no dated metagame sample); Matchup and format fit (D13) because there is no tournament link
• Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied deck has no title and no side deck guide data is empty (0 guides)
