Diabellstar Deck #772758 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Diabell, Queen of the White Forest; Snake-Eyes Doomed Dragon; Azamina fusions) reached through the Diabellstar / White Forest / Sinful Spoils engine, with Diabellze the White Witch and Diabellstar the Black Witch as the main bodies.; Azamina Fusion and Synchro extenders (Saint Azamina, Arms of Genex Return Zero, Chaos Angel) and a 2500-ATK Diabell body converting the resulting board.
• Turn 1 (going first): Open a searcher or Diabellstar starter, use Filia Diabell / Tales of the White Forest / WANTED to add a Diabell or White Forest body, then Synchro or Fusion into a boss while holding hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Effect Veiler) for interaction. Probability-based; no recorded boards.
• Turn 2 (going second): Use hand traps (16 hand-trap-text cards) to break the opponent's first summon or search, then rebuild through the Sinful Spoils / Diabell recursion lines. Probability-based; no recorded boards.
• Recovery: Recur Sinful Spoils cards from the GY and banish via WANTED / Sinful Spoils effects, and re-search Diabell or White Forest monsters with Filia Diabell, Curse of Diabell and Tales of the White Forest.
• After siding: Not evaluable: the deck supplies 0 side-deck cards and there is no post-side performance data.

Why it scores here

The deck is scored as a system, not as an average of its cards. Its engine is a multi-archetype mix (Diabellstar, Diabell, White Forest, Sinful Spoils, Azamina, Mulcharmy, Elfnote), with only 1.4% exact-name archetype purity and 71 off-archetype copies, so consistency is held down by conflicting starters rather than helped by coherence. The core archetype group gives an estimated 82% chance of at least one core card in a 5-card opening hand (Inferred), and 16 searcher-text cards and 16 hand-trap-text cards give it a real route to find a starter and to interact on the opponent's turn. Interaction density is high on paper (19 removal-text cards, 13 negation-text cards), which earns the end-board and interruption scores (Inferred from card text only). There are no recorded boards, so the combo ceiling and median are text-only inference and are scored conservatively. Popularity of the Diabellstar archetype (core cards in usage stats) confirms the list is real, but it did not earn points. The deck is Illegal (Extra Deck over 15, three copy-limit violations), so it is capped at a theoretical, structural-only score.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Combo secondary (informational only, not blended into weights). Structural ≈ 52, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal list (Extra Deck size and copy limits) (-8); Banlist exposure (Limited / Semi-Limited key cards) (-3); Engine conflicts (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Illegal list, so the result is theoretical/structural-only and the -12 legality modifier brings it down (0.80*52.4 + 0.20*45 = 50.9; 50.9 - 12 = 38.9 ≈ 39)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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: 16 hand-trap-text and 19 removal-text cards
• Strong search density (16 searcher-text cards) for finding starters
• Real boss density in the Extra Deck (Diabell Queen, Snake-Eyes Doomed Dragon, Azamina fusions, Chaos Angel)
• Core archetype cards are present at a high usage rate (11 of 16 core cards, ~69%)

Weaknesses

• Illegal as submitted: Extra Deck 18 (limit 15) and three copy-limit violations
• Low archetype purity (1.4%) with 71 off-archetype copies, so starters conflict
• No Side Deck, so no post-side plan
• High complexity with multiple engine lines, lowering pilotability

Critical choke points

• Starter reliance on Diabellstar the Black Witch / Filia Diabell / Diabellze (1 copy each)
• Extra Deck legality: the list cannot be played until it is cut to 15 Extra cards
• WANTED and Ash Blossom copy counts exceed their Limited / Semi-Limited limits

Recommended changes

Evidence & confidence

• Verified: Main Deck 54 cards; Extra Deck 18 cards; Side 0 (legality export); Extra Deck exceeds OCG maximum of 15; Copy-limit violations: Ash Blossom (3 vs 2), WANTED (3 vs 1), Diabell Queen (4 vs 3); Core usage: 11 of 16 core cards present (~69%); Archetype purity 1.4%; 71 off-archetype copies
• Inferred: Starter probability ~0.82 for at least one core card in 5-card hand; Hand-trap and removal density gives interruption resilience; Engine conflicts reduce D2 and D1
• Provisional: Meta Power (null) and matchup fit (D13) due to no dated metagame sample; Combo ceiling and median (no boards)
• 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 No Side Deck supplied (Side Deck size 0)
