Diabellstar Deck #769977 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Fusion, Link, Synchro) reached through Mitsurugi Ritual and Azamina/Sinful Spoils searches; no single reliable line is evidenced; Diabellstar the Black Witch (2 copies) plus Ecclesia and the Dark Dragon as a Synchro/Fusion board presence
• Turn 1 (going first): Search a Reptile or Mitsurugi engine piece with Mitsurugi no Mikoto or Pre-Preparation of Rites, then use hand traps (Ash Blossom, Ghost Ogre, D.D. Crow) to protect the starter; the deck has three incompatible engines so the plan depends on which starter is drawn
• Turn 2 (going second): Hand traps (14 hand-trap cards, roughly 84% chance of at least one in a six-card hand) interrupt the opponent's first summon, then the deck tries to rebuild through searchers and Mulcharmy draw effects
• Recovery: Searchers (about 20 searcher-text cards) and graveyard recursion (Mitsurugi monsters, Azamina GY effects) rebuild a hand; the recovery path is real but depends on which engine survives
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The list is Illegal: three Forbidden cards are run (Ame no Habakiri no Mitsurugi, Red-Eyes Dark Dragoon, Azamina Ilia Silvia) and four Limited or Semi-Limited cards exceed their copy limits, so the score is capped at 30 and labelled structural-only. Structurally the deck is a Toolbox list with real interaction density: 14 hand-trap cards and about 21 removal-text cards give a going-second plan that is more reliable than its going-first plan. It is not one engine. Only 2 of 68 copies are named Diabellstar, and it mixes Mitsurugi, Mulcharmy, Azamina, Sinful Spoils and Magician pieces, while 6 of the 18 core-usage cards are present, so engine coherence scores low. No combos were recorded, so the combo floor, median and ceiling are text-only inference and carry the widest uncertainty. The score comes from consistency, interaction and resilience on the system, not from averaging card scores, and not from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary; Midrange secondary, disclosed as a judgment from the mixed engine composition. Structural ≈ 50, Going First ≈ 45, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); engine conflicts (-4). Final formula: Illegal cap applied: 0.80*Structural(50) + 0.20*TournamentReliability(45) = 49, minus modifiers (-12) = 37, capped to 30 for an Illegal list (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Strong hand-trap and negation density (14 hand traps, 9 negation-text cards) for going second
• Many searchers (about 20) and graveyard recursion give recovery after disruption
• Several independent starters (Mitsurugi, Azamina, Mulcharmy) give redundancy against one interruption

Weaknesses

• Illegal list: three Forbidden cards and four over-limit copies
• Engine incoherence: only 2 of 68 copies are named Diabellstar, and the deck is split across three archetypes
• No Side Deck, so no post-side plan
• No recorded combos, so the conversion ceiling and median cannot be verified

Critical choke points

• Three Forbidden cards occupy slots that must be removed before the deck is legal
• Mitsurugi Ritual and Pre-Preparation of Rites are single-path routes to the Ritual engine
• The Diabellstar core is largely absent, so the archetype's named win conditions are not reliably reachable

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, with 3 Forbidden cards and 4 over-limit Limited or Semi-Limited copies; Main 55 and Extra 15 are legal size; Side 0 is legal; Deck composition: 14 hand traps, 20 searcher-text cards, 2.9% exact Diabellstar name purity
• Observed: No recorded combo boards (total_combos 0)
• Inferred: Consistency and brick estimates from the hypergeometric draw table; Going-second interaction read from hand-trap probability; Engine coherence read from archetype_spread
• Provisional: Matchup and format fit (no tournament link, no dated meta sample); Meta Power (null)
• 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 exists in YGOVN for going-first, going-second, matchup, brick or OTK rates Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null in the export
