Deck — Deck Power Evaluation
Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 53 |
| Going First | 55 |
| Going Second | 50 |
| Meta Power | provisional |
| Tournament Reliability | 40 |
- Primary strategy: Midrange
- Secondary strategies: Stun, Toolbox
- Format: ocg
Legality
Main 56 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).
Identity & game plan
- Win condition: Extra Deck threats (Chimeratech, Number/Xyz, Cyber Dragon Nova) backed by hand-trap protection (Inferred); Cyberdark/K9 boards that follow up after Cyber Dragon searches (Inferred)
- Turn 1 (going first): Open on Cyber Dragon / Cyberdark searchers and K9 Normal Summons, then hold hand traps (Ash Blossom, Ghost Belle, Ghost Ogre, Infinite Impermanence) for the next turn (Inferred)
- Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Nibiru and Disablaster to interrupt the opponent's first board, then rebuild with Cyber Dragon and Xyz/Link (Inferred)
- Recovery: Recycle through Cyber Dragon Herz, Nachster and Cyberdark Claw from the GY, and use the Mulcharmy draw engine to refill hand (Inferred)
- After siding: No side deck; no post-game adjustment is possible in best-of-3 (Verified)
Why it scores here
The deck's consistency rests on a dense set of searchers (21 searcher-text cards, about 92% chance of at least one in a 5-card opening hand) and 14 hand traps (about 84% chance of one in a 6-card going-second hand), which gives it a reliable early interaction layer. Its interaction density is the strongest structural feature: negation, hand traps and removal combine into a layered end-board that holds up through disruption. Conversion is weaker because no recorded boards exist, so the ceiling and median are inferred from text only and kept modest. The score is pulled down by the two Semi-Limited copy-limit violations, which make the list illegal and cap the result, and by the lack of a side deck. Popularity was not credited: the archetype core is only 3 copies and 70 of 73 copies are off-archetype, and the score comes from consistency, interaction and Extra Deck coverage on the system, not from averaging card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | Searcher-text 21 cards, P(≥1 in opening 5) ≈ 0.92; archetype core only 3 copies, P ≈ 0.25 (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Hand-trap and dead-card mix is high at 14 hand traps and 26 singletons; brick rate not computed from a list of this shape (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No parseable recorded boards; ceiling inferred from Chimeratech and Number Xyz text only (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No combos supplied, so the median is unmeasured and kept below the structural estimate (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Redundant hand traps (Ash, Ghost Belle, Ghost Ogre, Impermanence) and multiple recursion lines give several independent answers (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Cyberdark Claw, Cyber Dragon Herz and Mulcharmy draw effects provide reasonable card economy (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | 14 hand traps plus Lightning Storm, Feather Duster, Droll and Disablaster give broad, layered end-board interaction (Verified for card text, Inferred for quality) |
| D8 | Going-Second & Board-Breaking Power | 55 | Going-second hand-trap coverage ≈ 0.84 and Illusion Gate / Lightning Storm give board breaking, but no going-second data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Chaos Angel (3500), Magnamhut and Druiswurm (2500) and Cyber Dragon Nova give closing power, with no end-board ATK sample (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 56 main cards with 26 singletons and 70 off-archetype copies; the 3-copy core is thin and the deck runs many tech slots (Verified count, Inferred efficiency) |
| D11 | Extra Deck Efficiency & Coverage | 65 | 14 Extra Deck cards across Link, Xyz, Synchro and Fusion with several interchangeable threats (Verified count, Inferred coverage) |
| D12 | Side Deck Adaptability | 15 | Side deck is empty (0 cards), so no post-side plan exists (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | Archetype share is unavailable and no dated metagame sample exists (Provisional) |
| D14 | Pilotability & Error Tolerance | 55 | Multiple hand-trap timing windows and Cyber Dragon chains require frequent decisions (Inferred) |
How the score was computed
Strategy profile: Midrange primary, Stun secondary (interaction-heavy); profile weights used as-is, no blend applied. Structural ≈ 53, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Copy-limit violation (illegal list) (-15). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); Illegal cap applied
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.92 · 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
- Dense searcher and hand-trap package gives a consistent early interaction layer
- Layered negation, removal and hand traps protect the end-board
- Multiple Extra Deck closers (Chimeratech, Xyz, Link) give flexible threats
Weaknesses
- Two Semi-Limited copy-limit violations make the list illegal
- No side deck, so best-of-3 has no adaptation
- Thin 3-copy archetype core; 70 of 73 copies are off-archetype
- One unresolved passcode weakens legality and card-text verification
Critical choke points
- Cyber Dragon / Cyberdark searcher chain for the opening turn
- Reliance on hand traps being in hand rather than on the board when the opponent goes first
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One copy each of Ash Blossom & Joyous Spring and K9-17 Izuna | Legal filler from the 2-copy-limit allotment (e.g. one of the single-copy tech or staple slots) | Restores legality so the deck can receive a normal score |
| 2 | Unresolved passcode 10443957 | Verified legal card from the same role slot | Lets the legality check and card-text verification pass |
| 3 | Two lowest-impact off-archetype tech cards | A side deck of 3–8 cards covering the most-played opposing boards | Addresses the zero side-deck gap for best-of-3 play |
Evidence & confidence
- Verified: Copy-limit violations for Ash Blossom and K9-17 Izuna; Main 56 / Extra 14 / Side 0 counts; Card text and banlist tokens from evidence; Searcher-text count 21 and hand-trap count 14; Extra Deck breakdown: Link 4, Xyz 6, Synchro 1, Fusion 3
- Inferred: Starter hypergeometric estimates (P≈0.92 searcher, P≈0.84 hand trap going second); Strategy classification as Midrange with Stun secondary; Interaction layering and recovery quality from text
- Provisional: Meta Power (no dated metagame sample); Matchup and format fit (archetype meta share unavailable)
- Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link; archetype meta share and per-pilot record absent One passcode (10443957) unresolved and counted as main No win-rate telemetry; going-first/second, matchup and brick rates are Inferred or unknown Meta Power is provisional without a dated metagame sample
