Legality

Main 50 / Extra 22 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

  • Win condition: Link and Xyz boss monsters (Varar, Zebufera, Duralume, Endymion the Crescent Magistus) backed by Resonance Counter pressure from the Vaalmonica Pendulum zone; Magistus Fusion and Xyz boards (Aiwass, Zoroa, Ninaruru, Rilliona) with Magistus Chorozo negation
  • Turn 1 (going first): Open a Vaalmonica Pendulum scale (Angello, Dimonno, Selettrice) and a Vaalmonica spell to set up a Link Summon of Zebufera or Duralume, then use Vaalmonica Ereditare or Chosen Melody to protect the board
  • Turn 2 (going second): Use Ash Blossom, Maxx C, and Verre Magic to disrupt the opponent, then rebuild through Vaalmonica searchers and Pendulum scales
  • Recovery: Vaalmonica searchers (Scelta, Versare, Disarmonia, Intonare) and Verre Magic re-fetch Pendulum and Link pieces from the Deck and GY
  • After siding: Not evaluable: the deck has no Side Deck and the export contains no post-side data

Why it scores here

The deck opens reliably: the 26-copy Vaalmonica core has a 98% chance of at least one card in a 5-card opening hand (Inferred), and 21 searcher-text cards keep the engine fed. Its ceiling comes from Link and Xyz bosses backed by Resonance Counter pressure, and its interaction density (Ash Blossom, Maxx C, Ereditare, Chosen Melody, and Magistus negation) keeps the end board layered. Scoring is held back by the system's fragility: 45 of 50 main-deck copies are off the exact archetype name, the Extra Deck holds 22 cards against a 15-card limit, and the deck has no Side Deck. The deck is also Illegal in OCG (two Forbidden copies, Extra Deck over the limit), so the score is capped, and this is structural only. Popularity did not earn points, and card scores were not averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 70 P(at least 1 core card in 5-card hand) ≈ 0.98; multiple independent starters; no combo corpus to confirm (Inferred)
D2 Opening-Hand Quality & Brick Management 58 21 singletons, 3-copy pendulum scales and 2-copy searchers; some dead cards without their Pendulum or Link pieces (Inferred)
D3 Combo Conversion & Ceiling 62 Ceiling read from card text: Link and Xyz bosses with Resonance and Magistus boards; no recorded boards to measure (Inferred)
D4 Combo Floor & Median Output 45 No recorded boards, so median output cannot be measured; expected to be below ceiling because of conditional starters (Provisional)
D5 Interruption Resilience & Route Redundancy 60 Ash Blossom and Maxx C plus Vaalmonica searchers give independent lines; recursion is partly from text (Inferred)
D6 Resource Economy, Recovery & Grind 65 21 searcher-text cards and GY recursion through Verre Magic and Vaalmonica searchers (Inferred from text)
D7 End-Board & Interaction Quality 68 6 negation-text cards, 3 hand traps, and removal text (Inferred semantic read; the flags are Verified)
D8 Going-Second & Board-Breaking Power 60 Three hand traps (Ash x2, Maxx C) and going-second removal; no going-second win data (Inferred)
D9 Offensive Pressure & Closing Power 65 Link bosses at 2500-3000 ATK plus Resonance ATK reduction and direct-attack text (Inferred)
D10 Main Deck Efficiency & Flexibility 45 50 main-deck cards, 45 off exact archetype name, 33 distinct cards; cohesion is low across Magistus, Fiendsmith, and Endymion (Inferred)
D11 Extra Deck Efficiency & Coverage 35 22 Extra Deck cards exceed the 15-card limit by 7; Extra Deck coverage is wide but illegal (Verified size, Inferred use)
D12 Side Deck Adaptability 10 No Side Deck at all, so no post-side plan can be scored (Verified structure)
D13 Matchup Coverage & Format Fit 45 No dated metagame sample; archetype meta-share absent (Provisional)
D14 Pilotability & Error Tolerance 35 Four interacting archetypes, many Pendulum and Link timing decisions, and an illegal list; hard to pilot (Inferred)

How the score was computed

Strategy profile: Balanced (default; the primary strategy is a Midrange and Combo blend). Structural ≈ 55.5, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal: Forbidden cards and Extra Deck over limit (-12). Final formula: Illegal, so the normal formula is capped: 0.80*Structural(55.5) + 0.20*TournamentReliability(40) = 52.4, then modifier -12 for legality = 40 (theoretical/structural only; Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.98 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Core engine appears in nearly every opening hand (98% for the core group, Inferred)
  • Strong Link and Xyz boss options with Resonance pressure and layered negation
  • Searcher density (21 cards) keeps the hand and GY functional

Weaknesses

  • Illegal in OCG: two Forbidden copies and Extra Deck over limit
  • Low cohesion: only 37.5% of main-deck copies share the exact archetype name
  • No Side Deck, so no post-side adaptability
  • Four interacting archetypes make pilot error likely

Critical choke points

  • Pendulum scales: Vaalmonica Link and Pendulum-dependent cards need Resonance Counters, so a hand with no scale stalls the Link plan
  • Link Summon requirements (Zebufera and Duralume need 3 Resonance Counters on the right Monster type)
  • Extra Deck size: the excess 7 Extra Deck cards cannot all be used in one list
Priority Remove Add Reason
1 Number 60: Dugares the Timeless and D/D/D Wave High King Caesar Legal replacements within the Vaalmonica or Magistus core Two Forbidden copies make the list illegal; this is a prerequisite for any normal score
2 Off-archetype Extra Deck cards (Snake-Eyes Doomed Dragon, Necroquip Princess, Elder Entity Norden, Invoked Magistus Omega, D/D/D Wave) Vaalmonica and Magistus Link or Xyz cards only Extra Deck must be 15 or fewer and should match the engine
3 Off-archetype main-deck cards (Emissaries from Darkness, Mulcharmy Fuwalos, Elemental Saga Doriado, Fabled Lurrie) Pendulum, Link, or Resonance enablers Raises archetype purity and reduces brick risk
4 None (no Side Deck) A 15-card Side Deck with Ash Blossom copies and anti-Magistus or anti-Link answers Gives a post-side plan for best-of-3 play; currently none

Evidence & confidence

  • Verified: Legality: two Forbidden copies and Extra Deck 22 over 15 (OCG); Copy limits: Limited and Semi-Limited statuses match the export; Main Deck 50 cards, Side Deck 0 cards; Archetype purity: 37.5% exact-name; Vaalmonica 27, Magistus 17
  • Inferred: Core starter probability ≈ 0.98 (hypergeometric); Consistency and brick estimates from card text; Interaction quality from negation and hand-trap text; Ceiling read from Link and Xyz card text
  • Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament data)
  • Data gaps: No recorded combos: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry (going-first, going-second, matchup, brick rate) No Side Deck: post-side plan cannot be scored Meta Power is provisional without a dated metagame sample
