Vaalmonica Deck #772753 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 37/100 (±10 · Confidence: Low)

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

Legality

Main 57 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Extra-Deck beatdown from high-ATK Xyz/Synchro/Link monsters (Chaos Angel, Fiendsmith's Desirae, Exosisters Magnifica, Zebufera, Duralume), enabled by Vaalmonica Pendulum resonance and Exosister searches.; Exosister Xyz attrition: Exosister Karmael/Mikailis/Asophiel, with Mikailis banishing and Karmael detaching to stop the opponent's responses.
• Turn 1 (going first): Open a searcher (Vaalmonica Scelta/Versare/Invitare, Exosister Betrayal, Fiendsmith's Tract) into a Pendulum or Exosister starter; the opponent has limited interaction before the board goes up.
• Turn 2 (going second): Use the 7 hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Droll & Lock Bird) and Harpie's Feather Duster / Lightning Storm / Black Goat Laughs to answer the opponent's board, then convert into an Extra-Deck boss.
• Recovery: Re-searching is deep (22 searcher-text cards and 12 tech cards); Mulcharmy Fuwalos/Purulia draw cards when the hand is empty, and Exosister Pax can recover a second starter for 800 LP.
• After siding: Not evaluable: the deck has no Side Deck (Side Deck size 0), so there is no post-side plan.

Why it scores here

The deck's consistency rests on a Vaalmonica core (exact-name purity 25%), so the score comes from the system rather than from card-by-card power. The hypergeometric estimate of at least one archetype-core card in a 5-card opening hand is about 0.91, and about 0.92 for searcher-text cards, which supports a strong T1 access (Inferred). Seven hand traps and about 7 interaction cards give a good end-board and going-second answer profile. The deck spans three or four engines (Vaalmonica, Exosister, Fiendsmith, Mulcharmy), so its brick and conflict risk is high, and it has no recorded combos, so the ceiling and median can only be read from card text (Inferred). The deck is Illegal (three copy-limit violations), so it is capped as a theoretical, structural-only read. Popularity and archetype share did not earn points, and the card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange only; Toolbox not blended. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Copy-limit violations (Illegal list) (-8); Engine conflicts (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*51.45 + 0.20*40 ≈ 49.2; context modifiers total −12 (capped at the −12 floor). Illegal deck: theoretical/structural-only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.91 · key two-card combo ≈ — · full-brick estimate ≈ 0.09 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher and starter access across the archetype core (about 0.91 for at least one core card in hand 5, Inferred)
• Layered end-board interaction: 7 hand traps plus Duster, Lightning Storm, Black Goat Laughs and Droplet
• High-ATK Extra Deck closers (Chaos Angel 3500, Desirae and Magnifica 2800)

Weaknesses

• Illegal in OCG: three copy-limit violations
• Four engine families compete for the same 57 Main slots (25% exact-name purity)
• No side deck, so no post-side plan
• No recorded combos, so no ceiling/median evidence beyond card text

Critical choke points

• Each Fiendsmith over-limit card (Engraver, Tract) needs a legal copy count before the deck can be tested
• Pendulum resonance (Fiend/Fairy in the Pendulum Zone) gates the Vaalmonica Link Summons, Zebufera and Duralume

Recommended changes

Evidence & confidence

• Verified: Illegal copy-limit violations for Ash Blossom (3 vs 2), Fiendsmith Engraver (3 vs 1) and Fiendsmith's Tract (3 vs 1); Side deck size 0; Extra Deck 15 with 6 Xyz, 6 Link, 2 Fusion, 1 Synchro; Card stats: Chaos Angel 3500 ATK, Desirae 2800 ATK, Magnifica 2800 ATK
• Inferred: Opening-hand access ~0.91 for archetype core and ~0.92 for searcher text (hypergeometric); Interaction density and going-second hand-trap coverage from card text; Brick and engine-conflict risk from archetype spread (25% exact-name purity)
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: Illegal list: three copy-limit violations; scored only as a theoretical/structural read No combos supplied (combo data.total combos 0): ceiling, median and boards are text-only inference No side deck (Side Deck size 0): post-side adaptability cannot be scored No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry in YGOVN; going-first/second and matchup signals are Inferred or Unknown Data inconsistency: S:P Little Knight is in the Extra cards list (copies 1) and restricted cards (copies_run 1), but usage statistics reports in this deck false; treated as in the deck Meta Power is Provisional unless a dated metagame sample is supplied
