Deck — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (Confidence: Low)
- Primary strategy: Toolbox
- Secondary strategies: Midrange
- Format: ocg
Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Extra Deck boss monsters (Vaylantz Genesis Grand Duke, Arktos XII - Chronochasm Vaylantz, Jizukiru, Mekk-Knight Crusadia Avramax, Underworld Goddess) once a Pendulum or Kaiju board is established; no recorded lines to confirm this.; Kaiju summons from hand to force a board and then convert it with Dark Hole or Gameciel/Jizukiru negations (Inferred from text only).
- Turn 1 (going first): Pendulum-zone plays (Shinonome, Refrain, Saion, Voltage Viscount) into a Vaylantz World Field Spell, then a link or fusion extension; Inferred from card text, not from recorded boards.
- Turn 2 (going second): Kaiju hand summons (Gameciel, Jizukiru, Kumongous) and Ash Blossom / Droll & Lock Bird / Evenly Matched to answer the opponent's first line; Inferred.
- Recovery: Searchers (Vaylantz Mad Marquess, Couplet, Majesty Pegasus, Terraforming, Pot of Prosperity) to refill a hand; Inferred from text.
- After siding: None. The deck runs no Side Deck, so there is no post-side plan.
Why it scores here
The list is Illegal in OCG: it runs 4 Forbidden/over-limit cards (Called by the Grave, Fossil Dyna Pachycephalo, Triple Tactics Talent) and 3 copies of Limited Crossout Designator, so it receives a capped theoretical score rather than a normal Final Contextual score. The deck's pieces are mostly Vaylantz, Melodious, Kaiju and Pendulum cards with 0% exact-name Fossil purity and none of the Fossil usage-stat core, so the Fossil label earns no points. Structure is reasonable on paper: searchers (about 72% at least one in a 5-card opening hand), six hand traps, several negations, and a 15-card Extra Deck with strong boss options. Consistency is hurt by 16 Pendulum monsters, several mutually unrelated sub-engines, and 25 zero-Level spells, so the floor is much weaker than the ceiling. Score was computed as 0.80 x Structural 47 + 0.20 x Tournament Reliability 38 with a -12 modifier total, then capped at 25 because the list is Illegal; no card scores were averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 50 | Searcher group P(>=1 in 5-card hand) about 0.72; 3-copy core engine pieces about 0.25 each; no archetype-core usage data (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | Three sub-engines (Vaylantz, Melodious, Kaiju) plus Abyss Actor and Harpie pieces compete for the same Pendulum and Main slots; 25 zero-Level spells (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No recorded boards; ceiling inferred from boss Extra Deck monsters and Kaiju summons only (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded boards; median output unknown, likely below ceiling because of Pendulum and sub-engine conflicts (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Six hand-trap-type cards and Ash Blossom / Droll give several answers, but a single Pendulum route is a choke point (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Pot of Prosperity, Terraforming and Vaylantz searchers recover resources; no resource data (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Dark Hole, Harpie's Feather Duster, Evenly Matched, Kaiju negations and Ash Blossom give layered interaction; Forbidden cards removed from the count (Inferred from text) |
| D8 | Going-Second & Board-Breaking Power | 55 | Kaiju hand-summons and Dark Hole/Feather Duster give going-second answers; no going-second split data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | Several 2500-3300 ATK boss monsters (Jizukiru, Arktos XII, Avramax, Underworld Goddess); no damage or closing data (Verified stats, Inferred use) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 55 Main cards in 38 distinct names; 8 triples and 16 Pendulum monsters lower compactness; no garnet count available (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Extra cards (8 Link, 4 Fusion, 3 Xyz) with multiple good options; no Extra access data (Inferred) |
| D12 | Side Deck Adaptability | 10 | Zero Side Deck cards; no post-side plan or data (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament or meta sample; archetype label does not match the card mix (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Pendulum scale timing, Link and Fusion chains and many once-per-turn restrictions raise decision load (Inferred) |
