Despia Deck #718862 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

• Primary strategy: Combo
• Secondary strategies: Toolbox, FTK/Alternate-Win
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Fallen of Albaz-based Fusion Summons (Dragon that Devours the Dogma, Albion the Branded Dragon, Mirrorjade, Rindbrumm) into 2500-3000 ATK boards, supported by Branded Fusion and Super Polymerization.; Going-second recovery through searchers and Extra Deck Fusion lines; Mirrorjade and Rindbrumm as board breakers.
• Turn 1 (going first): Opening searcher (Branded in High Spirits, Aluber, Nadir Servant, Incredible Ecclesia) reaches Fallen of Albaz or a Branded Fusion route, then Fusion Summons a Level 8 boss from the Extra Deck.
• Turn 2 (going second): Hand traps (Droll & Lock Bird, Maxx "C", Branded Retribution) and Fallen of the White Dragon / Fallen of Albaz special summons to answer the opponent's board, then a Fusion boss.
• Recovery: GY recursion from Fallen of Albaz, Branded Opening and Ecclesia/Cartesia effects to rebuild a Fusion line after disruption (Inferred from card text; no recorded boards).
• After siding: No Side Deck is registered (0 cards), so there is no post-side plan; the list cannot be sided in a best-of-3 as built.

Why it scores here

The deck is scored as one connected Despia/Branded Fusion system, not as an average of its card scores. Its strongest feature is access: about 17 searcher-text cards give roughly 0.95 odds of at least one searcher in a 5-card opening hand (Inferred), and the Fallen of Albaz line gives a credible route to 2500-3000 ATK Fusion bosses. Those bosses, plus eight removal-text and seven negation-text cards, earn the closing and interaction scores. Conversion is held back because no real boards were recorded, so the ceiling and median are text-only inference, and the 9.1% exact-name archetype purity plus a spread across Dogmatika, Ecclesia, Swordsoul, Mulcharmy, Tri-Brigade and Springans creates engine conflicts. The deck has no Side Deck and runs Called by the Grave (Forbidden) plus three Limited or Semi-Limited cards over their copy limits, so it is illegal as built. Popularity and archetype usage stats confirm the list is real but did not add points, and the score is capped low under the Illegal guardrail.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: banlist exposure (-6); engine conflicts (-4). Final formula: Illegal deck: theoretical/structural-only. Uncapped no-meta formula 0.80*54 + 0.20*42 - 10 (modifiers) ≈ 42, then capped low to 30 under the Illegal guardrail. Meta Power null (Provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong searcher density (17 searcher-text cards) gives high access to the engine on going first (Inferred).
• Boss Fusions reach 2500-3000 ATK, and Mirrorjade adds 3000 ATK closing power (Verified stats).
• Layered interaction: 8 removal-text cards, 7 negation-text cards and hand traps (Verified text, Inferred quality).

Weaknesses

• Illegal as built: a Forbidden card and three over-limit Limited or Semi-Limited cards (Verified).
• No Side Deck (0 cards), so there is no post-side flexibility (Verified).
• Low exact-name purity (9.1%) and many sub-archetypes raise engine-conflict and brick risk (Inferred).
• No recorded boards, so consistency and combo ceiling are text-based estimates (Inferred).

Critical choke points

• Fallen of Albaz, which many Fusion routes and recursion effects depend on; running 1 copy makes it a single point of failure (Inferred).
• The Branded Fusion copy limit: 2 copies run where 1 is legal, so the illegal copy must go before the deck can be played (Verified).

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with four copy-limit violations (Called by the Grave Forbidden; Branded Fusion Limited; Super Polymerization and The Fallen & The Virtuous Semi-Limited).; Main 40 and Extra 15 are within Master Duel size rules; Side is 0.; Card text and stats for all 40+15 cards, and the Fallen of Albaz, Mirrorjade and Dragon that Devours the Dogma effects.; Archetype usage shows Fallen of Albaz, Branded Fusion and Mulcharmy Fuwalos as core cards.
• Observed: Usage stats show the list runs most of the archetype core cards (13 of 25 core cards present).
• Inferred: Searcher access ≈ 0.95 in a 5-card hand (hypergeometric estimate).; Brick and engine-conflict risk from 9.1% exact-name purity.; Interaction quality from negation and removal text.; Going-first and going-second splits from card text.
• Provisional: Meta power is null because no dated metagame sample exists.; Matchup fit (D13) rests on archetype usage only, with 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 title is null in the export Side Deck is empty (0 cards), so post-side performance cannot be assessed
