Identity & game plan

  • Win condition: Establish Vaalmonica Link monsters and control the opponent's board with hand traps and removal.; Leverage Magistus and generic toolbox cards for additional disruption and extra‑deck power.
  • Turn 1 (going first): Set Pendulum Zones, draw/search with Vaalmonica spells, and activate hand traps to protect while building Resonance Counters for Link summons.
  • Turn 2 (going second): Use the dense hand‑trap suite to stall opponent, then Link Summon high‑ATK Vaalmonica links and finish with removal.
  • Recovery: Stall with Infinite Impermanence, Droll & Lock Bird, and draw power; retrieve key monsters via searchers and graveyard recursion.
  • After siding: No side deck; rely on flexible hand‑trap chain and extra‑deck options to adapt after side‑step.

Why it scores here

The deck reliably opens with a solid hand‑trap suite and multiple searchers, giving consistent early protection and card advantage. Its engine can generate Resonance Counters to link‑summon powerful Vaalmonica monsters, but the pendulum setup is moderately fragile, keeping the median output modest. Strong interaction and removal options provide good resilience and closing power, while low archetype purity and the lack of a side deck limit adaptability and overall efficiency.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 60 P(at least one core starter in opening 5) ≈ 0.694; 3 copies of key Pendulum monsters each ≈0.338 (Inferred)
D2 Opening-Hand Quality & Brick Management 55 Hand contains 8 three‑copy cards and 10 singletons, giving a moderate brick risk with overlapping Pendulum options (Inferred)
D3 Combo Conversion & Ceiling 70 Potential full board with multiple Vaalmonica Link monsters and high‑ATK Varar suggests a ceiling around 70 (Inferred)
D4 Combo Floor & Median Output 45 Typical games resolve only hand traps and a single Link summon, yielding a median output near 45 (Inferred)
D5 Interruption Resilience & Route Redundancy 70 Eight hand traps (Infinite Impermanence, Ash Blossom, Droll, etc.) provide layered disruption, giving resilience ~70 (Inferred)
D6 Resource Economy, Recovery & Grind 65 17 searcher cards and LP‑gain effects enable resource recovery, supporting a resource score of 65 (Inferred)
D7 End-Board & Interaction Quality 68 Interaction density is high with 9 negation and 14 removal tags, plus powerful bosses like Varar, scoring ~68 (Inferred)
D8 Going-Second & Board-Breaking Power 60 Hand‑trap density for going‑second is 0.764, and removal options allow board breaking around 60 (Inferred)
D9 Offensive Pressure & Closing Power 65 Link monsters such as Varar (3000 ATK) and Zebufera (2500 ATK) give closing power ~65 (Inferred)
D10 Main Deck Efficiency & Flexibility 45 Only 45% archetype purity and 21 distinct main cards make the deck less compact (Inferred)
D11 Extra Deck Efficiency & Coverage 55 15‑slot Extra Deck holds 13 distinct cards, many generic links, yielding efficiency ~55 (Inferred)
D12 Side Deck Adaptability 30 No side deck present, limiting adaptability after side‑step (Inferred)
D13 Matchup Coverage & Format Fit 40 No tournament data; meta fit is provisional and estimated low at 40 (Provisional)
D14 Pilotability & Error Tolerance 50 Complex pendulum counter mechanics and many options lower pilotability to ~50 (Inferred)

How the score was computed

Strategy profile: Control. Structural ≈ 58, Going First ≈ 60, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: none. Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (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 suite for disruption
  • High interaction density with many removal and negation options
  • Flexible extra‑deck with powerful Vaalmonica links

Weaknesses

  • Low archetype purity; many off‑archetype cards dilute core
  • No side deck limits post‑side adaptability
  • Complex pendulum counter requirements create brick risk

Critical choke points

  • Need 3 Resonance Counters to summon Vaalmonica Link monsters
  • Reliance on specific Pendulum combos for engine activation
Priority Remove Add Reason
1 Some generic extra‑deck links (e.g., I:P Masquerena) that do not support the Vaalmonica engine More Vaalmonica core Pendulum monsters or cards that place Resonance Counters Increase starter consistency and reduce brick risk
2 None A side deck with anti‑meta floodgates (e.g., Dimensional Barrier) and extra removal Improve post‑side adaptability and matchup coverage

Evidence & confidence

  • Verified: Legality status and copy limits; Card text excerpts for hand traps and searchers
  • Inferred: Probability calculations for starter consistency; Brick risk estimation from copy histogram; Engine ceiling and floor based on card effects; Interaction density from role_tag_counts; Resource economy from searcher and LP‑gain cards; Closing power from high‑ATK Link monsters; Main‑deck efficiency from archetype purity; Extra‑deck efficiency from breakdown; Pilotability from pendulum complexity
  • Provisional: Matchup format fit due to missing tournament data
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per‑pilot match record absent no win‑rate telemetry exists in YGOVN (going‑first/second, matchup, game‑level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
