Ashened Deck #773161 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Fusion/Xyz/Link
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Field-Spell-driven Ashened engine: Obsidim, the Ashened City enables hand-Special-Summons (Priestess, King, Hero, Shaman) that feed Pyro fusions such as Veidos the Eruption Dragon of Extinction and Embers of the Ashened.; Fusion and Link finishers (Veidos the Dragon of Endless Darkness is absent; Garura, Norden, Favorite HERO and S:P Little Knight are present but off-core) and Queen of the Blazing Domain as a 3000-ATK beater.
• Turn 1 (going first): Set Obsidim via Terraforming or Awakening of Veidos, then hand-summon a Level 4 Ashened monster; unverified without combo boards.
• Turn 2 (going second): Hold Ash Blossom, Infinite Impermanence, Ghost Ogre and Droll & Lock Bird to answer the opponent's first line, then rebuild through Obsidim and the Ashened searchers.
• Recovery: Ashened for Eternity and Extinguishing the Ashened recover GY Pyro monsters; Obsidim returns to the Deck from the GY at End Phase for a card draw.
• After siding: Not assessable: the deck has no side deck (side_count 0), so no post-side plan exists.

Why it scores here

The list is illegal as submitted: three cards (Ash Blossom & Joyous Spring, Dominus Impulse, Super Polymerization) are run at 3 copies against a Semi-Limited limit of 2, so the deck cannot be entered in OCG play as built. The structural read is that the Ashened engine is coherent (18 exact-name Ashened cards plus generic enablers), with Obsidim's 25% opening-hand odds as the main consistency weak point, and the interaction suite (Ash, Impermanence, Ghost Ogre, Droll, Duster, Lightning Storm) is dense. No side deck, no combo boards and no tournament data exist, so floor, median and ceiling are text-based inferences. The score is capped at 25 because the list is illegal; the popularity of the Ashened archetype and the card-level strength of the staples did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Midrange secondary; disclosed as the default Combo profile. Structural ≈ 53.7, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist_copy_limit_exposure (-8); no_side_deck (-2); illegal_list_cap (0). Final formula: Theoretical cap for Illegal list: uncapped 0.80*53.7 + 0.20*42 - 12 (modifiers) ≈ 39; capped to 25 per legality rule (structural-only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Coherent Ashened core: Obsidim, Priestess, King, Hero, Shaman and Inferno are present at near-universal inclusion in the usage stats.
• Dense interaction suite: Ash, Impermanence, Ghost Ogre, Droll, Dominus, Duster and Lightning Storm give layered answers.
• High-ATK finishers: Veidos the Eruption Dragon of Extinction, Queen of the Blazing Domain and Nibiru.

Weaknesses

• Illegal as built: three Semi-Limited cards exceed their copy limit.
• Obsidim is a single-copy-dependent enabler with a roughly 25% opening-hand chance per 3-copy line.
• No side deck, so there is no post-side adaptation.
• Off-archetype dilution (exact-name purity 25.7%) and several Extra-Deck cards outside the core.

Critical choke points

• Obsidim in the Field Zone gates most hand-summon routes.
• Ash Blossom and Infinite Impermanence are the main answers to opposing interaction; the list is illegal until one copy of Ash and one of Dominus or Super Polymerization is removed.

Recommended changes

Evidence & confidence

• Verified: Legality: three Semi-Limited cards at 3 copies against a limit of 2 (Illegal).; Main 55 / Extra 15 / Side 0 sizes are within OCG size rules.; Ashened core inclusion ≈ 100% for Obsidim, King and Priestess in usage stats.; Exact-name archetype purity 25.7%.
• Inferred: Engine coherence and Obsidim access (hypergeometric P ≈ 0.25 per 3-copy line).; Interaction density from role flags and card text.; Going-second hand-trap coverage ≈ 0.79.; Ceiling from Veidos fusion text.
• Provisional: Meta Power (null).; Matchup fit (no tournament_context).
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot record are absent. No side deck: post-side plan and D12 are at the floor. No win-rate telemetry exists in YGOVN for this deck.
