Diabellstar Deck #773298 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 43 / Extra 18 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Synchro and Fusion boss monsters (Diabell, Queen of the White Forest; Diabellstar the Black Witch line; Elfnote June Pride) that pressure the board once established; Azamina fusion chains and Elfnote Seraphim Strelitzia 3000 ATK boards, if the Extra Deck is legal
• Turn 1 (going first): Open a starter (Diabellstar the Black Witch, Mulcharmy Fuwalos or Silvy) with Elzette / Filia Diabell-style searches, then Synchro or Fusion into a boss; hand traps are held back for the opponent's turn
• Turn 2 (going second): Use the six-card hand to present a hand trap (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Maxx C) and then rebuild the engine through the White Forest and Elfnote searchers
• Recovery: Recursion from the GY through Diabellze / Diabell Queen effects and Elfnote Regina / Tinia search, plus Curse of Diabell as a board wipe when two Diabell monsters are out
• After siding: Not assessable: the export contains no side deck (Side Deck size 0), so no post-side plan exists in this list

Why it scores here

The list cannot be scored as a normal legal deck: it runs six Forbidden copies across four cards, a Diabell Queen count over the limit, and an Extra Deck of 18 against a 15-card cap, so the final score is capped low and the evaluation is structural only. Structurally, the core engine is reasonably reachable: the Mulcharmy, Diabellstar and Silvy starters are at about 32% each in a five-card opening hand, and the archetype core group (16 copies) gives roughly 92% chance of at least one core card. The deck does have real interaction density (7 hand traps, 10 negation-text cards, 10 removal-text cards), which lifts end-board interaction and going-second strength. Against that, the main deck is spread across about four sub-archetypes (only 4.9% exact-name purity, 33 distinct main cards, 26 singletons), so brick and conflict risk is high, and there is no side deck, no combo data and no tournament record. The score comes from consistency and interaction on the system, not from averaging card scores or from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-8); dependence on Extra Deck legality (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 46, then modifiers -11 = 35, then capped to 25 because the deck is Illegal

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Strong interaction density: seven hand traps plus negation and removal text
• Core engine reachable in the opening hand (about 92% chance of at least one core card)
• Two-copy hand traps (Ash Blossom, Ghost Ogre) that are legal at their limits

Weaknesses

• Illegal list: six Forbidden copies and Diabell Queen over the copy limit
• Extra Deck of 18 exceeds the 15-card maximum
• Four sub-archetypes with only 4.9% exact-name purity raise brick and conflict risk
• No side deck, so no best-of-3 adjustment is possible

Critical choke points

• Forbidden Extra Deck monsters (Red-Eyes Dark Dragoon, Azamina Ilia Silvia, Baronne de Fleur) remove key Extra Deck routes
• The Diabell Queen engine needs 3 copies at most and currently runs 4
• Hand-trap plan on going second depends on 6-card hands with at least one of the 7 traps

Recommended changes

Evidence & confidence

• Verified: Legality: 43 Main, 18 Extra, 0 Side; 18 Extra exceeds the 15 maximum; Six copies of Forbidden cards and Diabell Queen over the 3-copy limit; Exact-name purity 4.9% and 33 distinct main cards; Hypergeometric starter probabilities from the resolved list
• Inferred: Brick risk and conflict risk from composition; Interaction density from role flags and card text; Going-second hand-trap coverage from the 68% probability
• Provisional: Meta power (no dated sample); Matchup fit and side-deck adaptability (no side deck or tournament data)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown No side deck in the export: Side Deck size 0 Meta power is Provisional unless a dated metagame sample is supplied
