Vaalmonica Deck #769499 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Pendulum-zone Resonance Counters enable Link Summons of Vaalmonica Link Monsters (Zebufera, Duralume, Varar) that pressure the board, with Chaos Angel, Number 39 and A Bao A Qu as extra-deck closers.; Fiendsmith Engraver/Tract Fusion route into Fiendsmith's Desirae, which is only partly supported by the list (Requiem and Sequence are present, the Fiendsmith core is thin).
• Turn 1 (going first): Set up two Pendulum Monsters in the Pendulum Zone, build Resonance Counters, then Link Summon a Vaalmonica Link Monster; Ash Blossom and Effect Veiler protect the first two steps.
• Turn 2 (going second): Hold a hand trap (about 85% chance of at least one in a 6-card hand) to negate the opponent's starter, then rebuild through Vaalmonica searchers and Link Summon.
• Recovery: Spells and monsters that search from the Deck (Vaalmonica Scelta, Versare, Invitare, the Vaalmonica spells) refill the hand; Lacrima and Fabled Lurrie can recur from the GY.
• After siding: No Side Deck is registered (side_count 0), so there is no post-side plan in the evidence; this is a major gap for a best-of-3 format.

Why it scores here

The deck is an Illegal list (two cards run 2 copies against an OCG limit of 1), so it receives a capped, structural-only score of 35 rather than a normal contextual score. Its strongest signals are the Vaalmonica core, which is almost always present (99.7% chance of at least one archetype card in an opening 5), and a dense interaction package of 10 hand traps and removal text that gives a good going-second read (about 85% to hold one hand trap in a 6-card hand). The Link and Synchro finishers (Chaos Angel 3500, Varar, Zebufera, Number 39) supply real closing power. Consistency and conversion are only Inferred from the hypergeometric draw table and the text scaffold, since there are no recorded boards. The score is not driven by Vaalmonica's popularity, and it is not an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 58.4, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy-limit violation (banlist exposure) (-8); No side deck (-4); Illegal-deck cap (-8). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 55.7, minus 12 modifiers = 43.7, capped at 35 because the deck is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 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

• Core archetype is almost always accessible (0.997 chance in an opening 5).
• 10 hand traps give going-second interaction (0.845 chance of one in a 6-card hand).
• Strong Link and Synchro closers (Chaos Angel 3500, Varar, Zebufera, Number 39).
• 18 searcher-text cards support consistency.

Weaknesses

• Illegal: Fiendsmith Engraver and Fiendsmith's Tract each run 2 copies against a limit of 1.
• Purity is 41.8%; 32 of 55 cards are off-archetype, spread across Fiendsmith, Bystial and Forbidden.
• No Side Deck (0 cards) for a best-of-3 format.
• Pendulum + Link engine has many decision points.

Critical choke points

• Two Pendulum Monsters must be placed to build Resonance Counters; without them the Link Summon route does not open.
• The Fiendsmith Engraver/Tract line depends on limit-1 cards that are run twice, so it is illegal as built.

Recommended changes

Evidence & confidence

• Verified: Illegal status: Fiendsmith Engraver and Fiendsmith's Tract over the OCG copy limit (2 vs 1).; Main 40 and Extra 15 are within the OCG size rules.; No Side Deck registered (side_count 0).; Card stats and banlist statuses from the evidence pack.
• Inferred: Engine accessibility 0.997 for the archetype core and 0.338 for a 3-copy starter in an opening 5.; Hand-trap coverage of 0.845 going second.; Interaction quality and recovery from searcher and recursion text.
• Provisional: Meta power and matchup fit: no dated metagame sample or tournament link.
• Data gaps: Deck is Illegal; the normal Final Contextual score is replaced by a capped theoretical score. No recorded combos, so combo floor, median and ceiling are text-only inference. No tournament link or archetype meta-share; matchup and meta fit are unknown. No win-rate telemetry; going-first and going-second splits are Inferred. Side Deck is empty, so post-side adaptability cannot be measured.
