Diabellstar Deck #773237 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link and Fusion Extra Deck threats (Flamberge Dragon, Volcanic Emperor, Salamangreat Raging Phoenix, Amblowhale) after Volcanic and Snake-Eye searches; Mulcharmy draw-and-disruption value on the opponent's summons
• Turn 1 (going first): Open a Volcanic or Snake-Eye searcher, search the second engine piece, and summon a Link or Fusion threat. Theoretical only, because no combo boards were supplied.
• Turn 2 (going second): Play a hand trap (Ash Blossom, Droll, Maxx C, Red Reboot, Ghost Ogre) on the opponent's first engine, then rebuild through Mulcharmy draw and Volcanic searches. Theoretical only.
• Recovery: Recursion through Volcanic Rimfire, Snake-Eye Oak and Volcanic Emission from the GY, plus Mulcharmy draws on the opponent's summons
• After siding: Not assessable: the deck runs no Side Deck (side_count 0)

Why it scores here

The list is Illegal: it runs Triple Tactics Talent and Original Sinful Spoils - Snake-Eye, both Forbidden in OCG, so it receives a structural-only read capped at 20 rather than a normal contextual score. The structure itself is a Volcanic, Mulcharmy and Snake-Eye midrange shell with 8 hand traps, 14 searcher-text cards and 10 link and fusion Extra Deck threats, and it earns points for interaction density and Extra Deck usage. Consistency is middling: each 3-copy starter is live in the opening 5 only about 25% of the time, and the archetype-core group reaches about 56%. The Diabellstar label is not what the list plays, since only 2 of 55 Main Deck cards are named Diabellstar and 4 of 16 core cards are present. No combo boards, tournament link, guides or side deck were supplied, so no points come from popularity, meta share or an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun is recorded as a secondary label only, not blended into the weights. Structural ≈ 45, Going First ≈ 44, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12); illegal cap (0). Final formula: Structural 45 and Tournament Reliability 35 give 0.80*45 + 0.20*35 = 43; Meta is provisional; the -12 banlist modifier brings it to 31; Illegal cap applied, so the final score is 20 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Eight hand traps and ten negation-text cards give interaction on both turns
• Three-copy Volcanic and Mulcharmy core gives consistent starters and draw
• Extra Deck of 10 Link and 5 Fusion monsters with strong ATK (2600 to 3100) gives closing power
• Three independent engines (Volcanic, Mulcharmy, Snake-Eye) give route redundancy

Weaknesses

• Illegal: two Forbidden cards (Triple Tactics Talent, Original Sinful Spoils - Snake-Eye) are in the Main Deck
• Archetype label mismatch: Diabellstar is labelled but only 2 Diabellstar cards are present, and 4 of 16 core cards appear
• No Side Deck, so there is no post-side adaptation
• Engine piles are diffuse, with 35 distinct Main Deck names and 20 singletons
• No combo evidence, so the power of the lines is untested

Critical choke points

• Removing the two Forbidden cards leaves Volcanic and Snake-Eye searches depending on single copies
• Opening-hand starter reliability is about 25% for a 3-copy engine piece going first

Recommended changes

Evidence & confidence

• Verified: Status Illegal: Triple Tactics Talent and Original Sinful Spoils - Snake-Eye are Forbidden and over the limit (legal_copies 0); Main 55 and Extra 15 are within OCG size rules; Side is 0; Extra Deck is 10 Link and 5 Fusion; no Synchro or Xyz; Archetype core group: 8 copies in deck; 4 of 16 usage-core cards present
• Inferred: Starter P(at least 1 in opening 5) = 0.25 for 3-copy engine pieces (hypergeometric); Interaction density is high from hand-trap and removal text flags; Going-second hand-trap P(at least 1 in 6) = 0.63
• Provisional: Meta Power is null; no dated metagame sample was supplied; Matchup fit is not measured
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta share and per-pilot record are absent No win-rate telemetry: going-first, going-second, matchup and brick rates are not measured No Side Deck: post-side plan cannot be evaluated Deck title is null
