Diabellstar Deck #772971 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

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

Legality

Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Diabell / Azamina Synchro and Fusion bosses (Diabellze the White Witch, Diabellstar Vengeance, Azamina line) reached through Diabellstar the Black Witch and Sinful Spoils recursion (Inferred from card text); Sinful Spoils Spell/Trap recursion via WANTED and Deception of the Sinful Spoils (Inferred from card text)
• Turn 1 (going first): Open with Diabellstar the Black Witch or a Mulcharmy line to reach a Synchro/Fusion boss, using Ash Blossom and Infinite Impermanence only as protection (Inferred)
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Infinite Impermanence and Forbidden Droplet to break the opponent's first line, then rebuild through Filia Diabell or Silvy (Inferred)
• Recovery: Searchers (13 searcher-text cards) and Pot of Sloth refill the hand; Tales of the White Forest and Filia Diabell add an engine piece (Inferred)
• After siding: Not evaluable: side_count is 0, so there is no post-side plan

Why it scores here

The deck's consistency rests on an archetype-core group of 16 copies, which gives about an 85% chance of at least one core card in a 5-card opening hand (hypergeometric, Inferred), but each individual starter (Diabellstar the Black Witch, 3 copies) is only about 26% per opening hand. Its strongest systemic features are 16 negation-text and 18 removal-text cards plus 8 hand traps, which give it real interaction breadth on both turns. Its weaknesses are a low exact-name archetype purity (4.3%, with 67 off-archetype copies spread across White Forest, Azamina, Mulcharmy, Sinful Spoils and others) and 20 singleton main-deck slots, which lower the odds that any given hand is coherent. No combo boards, guides, deck-level stats or tournament data were supplied, so the combo ceiling and floor are text-only inferences, and popularity or archetype usage did not earn points. The list is Illegal (two copy-limit violations and an Extra Deck of 17), so per the rubric it gets a theoretical, structural-only score capped at 40, and the scores were not averaged from individual cards.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 58, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-6); no side deck (-2). Final formula: Combo profile: Structural = 55.06 -> 55; TR = 48; 0.80*55 + 0.20*48 = 53.6; modifiers -8 -> 45.6; Illegal list capped at 40 (theoretical/structural only, no normal Final Contextual score)

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

• Broad interaction: 16 negation-text and 18 removal-text cards, 8 hand traps
• Strong boss ATK in the Extra Deck (up to 4000)
• Multiple GY-recursion routes after disruption

Weaknesses

• Illegal list: two copy-limit violations and Extra Deck of 17
• Low archetype purity (4.3% exact name, 67 off-archetype copies)
• 20 singleton main-deck slots lower consistency
• No side deck

Critical choke points

• Ash Blossom and Ghost Belle as the main protection layer; loss to a Droll-style or hand-trap-heavy opponent leaves few alternatives
• Diabellstar the Black Witch as the opening starter (3 copies, P about 0.26 per hand)
• Sinful Spoils cluster (WANTED limited to 1 copy) as the recursion engine

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: Ash Blossom 3 vs 2 legal, WANTED 3 vs 1 legal, Extra 17 > 15; Banlist statuses: Ash Blossom Semi-Limited, WANTED Limited, Harpie's Feather Duster Limited; Copy histogram and Extra Deck breakdown (9 Fusion, 8 Synchro); Card stats and text excerpts used for role tags
• Inferred: Opening-hand probabilities (hypergeometric) for core and starter groups; Functional roles (protection, recursion, bricks) from card text; Going-first and going-second plans; Brick rate and resilience estimates
• Provisional: Meta and format fit (D13), Meta Power (null)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate or matchup telemetry in YGOVN Meta Power is provisional without a dated metagame sample No side deck, so post-side plan and D12 are unmeasured Deck title is null
