Identity & game plan

Win condition: Link Summon high-ATK Vaalmonica Link monsters (Zebufera, Duralume, Varar) after building 3+ Resonance Counters in the Pendulum Zone; Non-archetype Link/Xyz closers (Underworld Goddess, Tornado Dragon, Steelswarm Roach) when the Vaalmonica engine is stalled
Turn 1 (going first): Search a Vaalmonica monster or Spell with a searcher, set Pendulum scales, build Resonance Counters, and Link Summon a 2500+ ATK Link monster
Turn 2 (going second): Use hand traps (Droll & Lock Bird, Nibiru, Vaalmonica Ereditare) to stop the opponent's first board, then rebuild the Pendulum/Link line
Recovery: Ereditare can banish from the GY to recur Vaalmonica cards from the Extra Deck, GY and banishment; searchers refill the hand
After siding: Not applicable: no side deck is present and no post-side data is supplied

Why it scores here

The deck's score comes from how the system opens and converts, not from card power or popularity. Eight searcher-text cards give about a 95% chance of at least one searcher in the opening five, which makes the Vaalmonica engine reliably reachable, though each two-copy starter alone is only about 45% to appear. Its ceiling is high on paper: Varar, Creation and the Ereditare negation chain can convert a Resonance Counter board into strong pressure. Median output is much lower because the Pendulum-zone counter requirement gates every Link Summon, and no recorded boards exist to confirm how often that gate opens. Interaction is layered across negation, destruction and summon-negation text, and three hand traps give it a real going-second plan. Nothing in the score rests on the archetype's usage share, and no averaging of individual card scores was used.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	72	Searcher-text group P(≥1 in opening 5) ≈ 0.95; each two-copy engine starter ≈ 0.45 going first; Pendulum-counter setup still required (Inferred)
D2	Opening-Hand Quality & Brick Management	66	Eight searcher-text cards and three hand traps keep most hands live; four Pendulum monsters plus Book of Eclipse, Forbidden Droplet, Droll ×2 and Nibiru add dead-draw risk; full-brick rate not computed (Inferred)
D3	Combo Conversion & Ceiling	70	No parseable boards; ceiling read from text: Varar at 3000 ATK, Creation's +1200 at 6 counters, and Ereditare negation chains (Inferred semantic)
D4	Combo Floor & Median Output	55	No recorded boards, so median and floor are text-only inference; the counter gate keeps the typical line well below the text ceiling (Inferred)
D5	Interruption Resilience & Route Redundancy	62	Three hand traps plus Ereditare and Nibiru recursion give several independent answers; hand-trap group P(≥1 in going-second 6) ≈ 0.68 (Inferred)
D6	Resource Economy, Recovery & Grind	62	Searchers and Ereditare GY/banish recursion regenerate cards; no resource signature data available (Inferred)
D7	End-Board & Interaction Quality	74	Negate and destroy text on Ereditare, Zebufera, Forbidden Droplet, Steelswarm Roach, Underworld Goddess and Tornado Dragon gives layered interaction; no observed interaction density (Inferred from text)
D8	Going-Second & Board-Breaking Power	66	Going-second rests on hand-trap access (≈0.68) and Nibiru's tribute-summon sweep; board-breaking density known from text only (Inferred)
D9	Offensive Pressure & Closing Power	68	Link closers at 2500–3000 ATK (Zebufera, Duralume, Varar, Underworld Goddess); ATK values verified, end-board use inferred (Verified stats, Inferred use)
D10	Main Deck Efficiency & Flexibility	64	20 Main cards, 15 distinct, 10 singletons and 5 two-copy lines; 9 non-exact-archetype Main copies dilute engine density; size within Duel Links rule (Verified)
D11	Extra Deck Efficiency & Coverage	60	Full 9/9 Extra with 7 Link and 2 Xyz; four non-archetype Extra cards are flex or tech slots (Verified)
D12	Side Deck Adaptability	40	Side zone is empty and no post-side data is supplied, so adaptability is scored low (Verified structure; Provisional outcome)
D13	Matchup Coverage & Format Fit	50	No tournament link or dated meta; archetype core usage is 100% for the Vaalmonica core list, which confirms it is real but not that it is strong (Provisional)
D14	Pilotability & Error Tolerance	50	Multi-step Pendulum-to-Link sequencing gated by Resonance Counters; decision-heavy, moderate-to-high complexity (Inferred)

How the score was computed

Strategy profile: Combo profile used as the weight set; Midrange noted as secondary strategy but not blended into weights. Structural ≈ 64.7, Going First ≈ 66, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 58. Modifiers: Pendulum-zone choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*64.7 + 0.20*58 = 63.4, then -2 modifier = 61

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.45 · 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

Searcher density (8 cards, ≈95% to hit one in the opening five) makes the engine reachable
Layered interaction: negation, destruction and summon-negation across Ereditare, Zebufera, Droplet, Steelswarm Roach, Underworld Goddess and Tornado Dragon
High-ATK Link closers (2500–3000) with multiple routes

Weaknesses

Pendulum-zone Resonance Counter gating makes the median line far below the text ceiling
Nine non-exact-archetype Main copies (Droll ×2, Nibiru, Droplet, Book of Eclipse and others) dilute engine density
No side deck, so no post-side adaptation

Critical choke points

Pendulum-zone Vaalmonica monsters must be on the field to build Resonance Counters, so losing the Pendulum zone stops the Link route
Link Summon on Zebufera and Duralume requires 3 counters on Fiend or Fairy monsters in the Pendulum zone; a single counter-line miss blocks it

Recommended changes

Priority	Remove	Add	Reason
1	Book of Eclipse	A second searcher or Pendulum-monster consistency card within the archetype	It is a non-engine card that does nothing for the Pendulum/Link line on most hands and adds dead-draw risk; the reason is consistency, not a measured win rate (Inferred)
2	Forbidden Droplet	An archetype Spell/Trap that builds Resonance Counters	It is off-archetype and only a one-copy negation tech, which weakens engine density (Inferred)

Evidence & confidence

Verified: Legal size (20 Main, 9 Extra, 0 Side) within the duel-links rules; All cards Unlimited; no restricted cards; Exact-name archetype purity 69%; Link ATK and Link rating values
Observed: Archetype usage stats: 100% core inclusion for Vaalmonica core cards
Inferred: Searcher and starter hypergeometric estimates; Hand-trap access on going second; Interaction density and resilience from card text; Pilotability complexity
Provisional: Meta power (null); Matchup coverage and format fit (no dated meta); Going-second plan quality without post-side or tournament data
Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchup or brick/starter rates Meta Power is Provisional without a dated metagame sample No full-brick rate computed
