Diabellstar Deck #769757 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Inferred: Fusion Summon of Diabellstar/Chimera/Azamina end-boards (Chimera the King of Phantom Beasts, Berfomet, Dark Magician of Destruction, Super Starslayer TY-PHON) from the Extra Deck via Chimera Fusion and Sinful Spoils support; Inferred: Diabellze the Original Sinkeeper and Guardian Chimera as high-ATK closers once the starters land
• Turn 1 (going first): Inferred: open a 2-card starter (Diabellstar the Black Witch, Gazelle, Mirror Swordknight or Chimera Fusion) and search Chimera Fusion or the Sinful Spoils line into a Fusion Summon
• Turn 2 (going second): Inferred: rely on Ash Blossom, Droll & Lock Bird, Maxx C, Infinite Impermanence and PSY-Framegear Gamma to disrupt the opponent, then rebuild through the Sinful Spoils and Chimera searchers
• Recovery: Inferred: 14 searcher-text cards and recursion from the Graveyard (Susurrus, Master Tao, Chimera names) allow re-searching after an interruption
• After siding: Not applicable: the deck has no Side Deck, so no post-side plan exists in the evidence

Why it scores here

The deck is Illegal in OCG because two Forbidden cards (Red-Eyes Dark Dragoon and Azamina Ilia Silvia) are run at 1 copy each where 0 are legal, so it receives only a structural read capped at 25 and no normal Final Contextual score. The structural read comes from the system: three copies each of Diabellstar the Black Witch, Chimera Fusion and Gazelle give a 0.34 chance of at least one in a 5-card opening hand, with 14 searcher-text cards lifting the chance of a searcher at 0.90 (Inferred). Interaction is dense (8 hand traps, 15 negation-text cards, 14 removal-text cards) and carries resilience, but the lack of recorded boards means the combo ceiling and median are text-only and low-confidence. Popularity did not earn points: Diabellstar usage stats only confirm the archetype is played, and the deck's exact-name archetype purity is 5.5%, which weighs against consistency. No side deck, no tournament data and no combo boards exist, so going-second, matchup and post-side dimensions stay Provisional, and the score was not derived by averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: Illegal cap: uncapped = 0.80*52 + 0.20*40 + (-12 banlist modifier) ≈ 38; capped at 25 because the deck is Illegal (over-limit Forbidden cards). Meta Power is null/Provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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

• Three copies each of the key starters (Diabellstar the Black Witch, Chimera Fusion, Gazelle) give a reasonable chance of a live opening
• Dense hand-trap, negation and removal text across 8 to 15 cards gives layered interaction
• High-ATK Fusion/Synchro/Xyz closers

Weaknesses

• Illegal: two Forbidden cards over the copy limit
• Only 5.5% exact archetype purity with 52 off-archetype copies
• No side deck
• No combo boards or win-rate data to validate the line

Critical choke points

• Chimera Fusion and Diabellstar the Black Witch: each has a 0.34 chance of appearing in an opening 5, so an opening without them is a likely brick
• Extra Deck access: 15 Extra slots with 2 illegal cards means a Forbidden card can be drawn in place of a legal one

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal in OCG: Red-Eyes Dark Dragoon and Azamina Ilia Silvia are Forbidden with 0 legal copies, each run once; Main 40 and Extra 15 are within size rules; Side 0 is within size rules; Copy histogram and type spread from the export; Usage stats: Mulcharmy Fuwalos 66.7%, Diabellstar the Black Witch 57.4%, Azamina Mu Rcielago 74.1% (archetype-level)
• Inferred: Primary strategy Combo; secondary Toolbox; Starter access from hypergeometric draws (0.34 for 3 copies, 0.90 searcher group); Interaction density from card text (15 negation, 14 removal); Going-second strength from hand-trap probability (0.76)
• Provisional: Meta Power (null, no dated metagame sample); Matchup coverage and format fit (D13); Going-second and post-side performance
• Data gaps: no combos supplied: combo floor/median/ceiling is text-only inference no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied no Side Deck, so post-side plan cannot be evaluated
