Diabellstar Deck #772500 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 43 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Synchro and Fusion boards built from Diabellstar, Elfnote and Azamina bosses (Diabellstar Vengeance, Diabell Queen, Elfnote June Pride, Cosmic Blazar Dragon) that push through 2500-4000 ATK; Diabellze and Rciela-style Synchro boards that grind via searches and recursion
• Turn 1 (going first): Open on a Searcher (Tales of the White Forest, Elzette, Diabellstar the Black Witch) to fetch a Synchro or Fusion boss, then summon a second engine monster through Diabellstar's Special Summon
• Turn 2 (going second): Hold Ash Blossom and Maxx C to answer the opponent's first starter, then rebuild through Elzette and Silvy searches into a boss
• Recovery: Recover the Elfnote and White Forest searchers from the GY and banish or re-search them through Filia Diabell and WANTED
• After siding: No side deck is registered, so no post-side plan can be scored

Why it scores here

The deck's engine is accessible: 20 searcher-text cards and a 16-copy archetype core give about a 0.92 chance of at least one core card in a 5-card opening hand (Inferred). Its ceiling comes from a fast Synchro and Fusion boss package, and Diabellstar Vengeance and the Elfnote bosses reach 2500-4000 ATK. Interaction is layered across two hand traps, Maxx C, Crossout Designator and several negating bosses, which earns the interaction score even though none of it counts for legality. The score is low because four Forbidden cards and one Extra Deck overflow make the list illegal, so the final value is capped; popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: 0.8 Midrange + 0.2 Toolbox (by judgement; not formally derived). Structural ≈ 54, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-12); illegal_cap (-8). Final formula: Uncapped: 0.80*54 + 0.20*35 + modifiers(-12) = 38; capped to 30 because the list is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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 searcher suite (20 searcher-text cards) makes the core engine reliably accessible
• Layered interaction: two Ash Blossoms, Maxx C, Crossout Designator and negating Synchro bosses
• High-ATK boss package (Diabellstar Vengeance, Elfnote June Pride, Cosmic Blazar Dragon)

Weaknesses

• Illegal as built: four Forbidden cards and an Extra Deck of 16
• Three archetypes (White Forest, Elfnote, Azamina) plus generic staples dilute engine coherence
• No Side Deck, so no post-side adaptability
• No recorded combos or win-rate data to validate any line

Critical choke points

• Starter density depends on a single Diabellstar Black Witch and Elzette pair (2 copies each)
• Two-card dependence on Synchro Summon routes for the boss line
• Recovery depends on GY searchers that the 16-copy core may not reach

Recommended changes

Evidence & confidence

• Verified: Legality: 4 Forbidden copies, Extra Deck 16 vs 15 limit, Main 43 within 40-60; Card text for Diabellstar Vengeance, Elfnote June Pride, Cosmic Blazar Dragon, Ash Blossom & Joyous Spring, Maxx C; Usage: Diabellstar core and Elfnote/Azamina cards show 52-73% inclusion in archetype stats
• Inferred: Opening-hand accessibility P ≈ 0.92 for the core group; Interaction layering from text and flags; Going-first and going-second estimates
• Provisional: Meta Power is null; no dated metagame sample; Matchup fit (D13) has no tournament link or win-rate data
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: meta-share and per-pilot match record are absent No win-rate telemetry for going-first/second, matchup, or brick/starter rates No Side Deck registered Meta Power is provisional unless a dated metagame sample is supplied
