Deck — Deck Power Evaluation
Final Contextual Deck Power: 32/100 (±8 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 36 |
| Going First | 42 |
| Going Second | 41 |
| Meta Power | provisional |
| Tournament Reliability | 28 |
- Primary strategy: Combo
- Secondary strategies: Toolbox, Control
- Format: ocg
Legality
Main 46 / Extra 21 / Side 0 — status: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Link-based combo into board negation/removal (unverified due to legality); Ritual summoning for mid-game pressure via Water Leviathan or Cyberse Magician
- Turn 1 (going first): Assemble Link board with interaction; blocked by deck illegality
- Turn 2 (going second): Use hand traps and removal to breach opponent board; incomplete without combo evidence
- Recovery: Graveyard recursion via @Ignister and Mathmech recursion effects; cost-heavy and redundancy-limited
- After siding: No side deck present (0/15); unknown post-side strategy
Why it scores here
This deck is **illegal in OCG** (Maxx "C" Forbidden, Extra Deck 21/15 oversized), so the evaluation is structural/theoretical only and capped low. The core @Ignister/Mathmech engine (7 exact-name copies, 45 Cyberse total) suffers from weak purity (~8% archetype core in usage stats), missing 23 of 25 meta-standard cards (Firewall Dragon Singularity, Cynet Conflict, Allied Code Talker @Ignister, Droll & Lock Bird, Harpie's Feather Duster all absent). No combo evidence or tournament data supplied; consistency and median output are text-inferred and highly uncertain. Opening hand quality is vulnerable to bricks (Magical Mallet suggests mulligan risk), and the 21-card Extra Deck has 6 flex/redundant slots unsuitable for combo lines. The deck runs 16 searchers and 6 hand traps, suggesting toolbox intent, but illegality and missing core cards prevent a meaningful final score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 45 | P(≥1 @Ignister starter in hand 5) ≈ 0.30; 3-card bootstrap chain via Achichi→Pikari→Backup; only 2 of 25 meta-core cards present (Inferred; Observed via usage_statistics) |
| D2 | Opening-Hand Quality & Brick Management | 38 | Copy histogram skewed to singles (28/35 distinct); Magical Mallet 2x indicates hand clog; no combo evidence to confirm hand quality floor (Inferred) |
| D3 | Combo Conversion & Ceiling | 35 | Extra Deck 21/15 illegal; no scored combos supplied; best line inferred from text: Link climb via Dark Infant/Transcode/Decode to Allied Code Talker (absent) or Firewall Singularity (absent); ceiling ~65 if legal and fully assembled (Inferred; Observed via card text hints) |
| D4 | Combo Floor & Median Output | 32 | No median boards measured; median estimated 55–65 on successful T1 line, but inconsistency and missing core cards suggest median floor ~50 across all hands (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 40 | Starter diversity low (Achichi/Pikari/Backup 3x each, Backup Tuner); limited to ~2–3 independent lines; recursion via Doyon/Firewall Saber Dragon/Backup recovery; no redundancy for multiple interruptions (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 42 | Resource economy weak: Backup discards 1, A.I. Meet You costs 2300 LP, Cynet Mining costs hand mill; net advantage estimated neutral to slightly negative per line; grind recovery via Doyon limited (Inferred) |
| D7 | End-Board & Interaction Quality | 48 | End board: 2–4 negations/removal pieces (Firewall Dragon, Allied Code Talker interaction, Transcode co-link boost, Dark Templar recursion); interaction_density inferred ~2.5; no layering depth confirmed (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 44 | 6 hand traps (Ash 2x, Effect Veiler 2x, Infinite Impermanence 1x, Maxx "C" 1x Forbidden); board breaker via Cyberse Desavewurm Fusion; going-second tech thin and reliant on going-first board breach (Inferred) |
| D9 | Offensive Pressure & Closing Power | 35 | Offensive ceiling: Firewall Dragon Darkfluid 3000 ATK, Firewall Dragon Singularity (absent) 3500; minimal piercing/direct; closing power ~45 (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 38 | Main 46/40–60 legal but oversized Extra forces efficiency loss; 15 Spell/Trap for search/protection; core cards sparse; efficiency score pulled down by illegal composition (Verified via legality status) |
| D11 | Extra Deck Efficiency & Coverage | 25 | Extra Deck 21/15 (6 cards illegal); 16 Link, 2 XYZ, 2 Synchro, 1 Fusion; redundancy high (2x Dark Infant, 2x Firewall variants); many flex slots unsuitable for combo lines; efficiency severely compromised (Verified; Inferred) |
| D12 | Side Deck Adaptability | 0 | No side deck (0/15); post-side plan unknown and unevaluable (Verified) |
| D13 | Matchup Coverage & Format Fit | 15 | Archetype meta-share unknown (tournament_context unavailable); 8% archetype-core purity vs 92% meta-standard, yet 23 meta-cards missing; format fit for OCG unverifiable; score reflects unknown matchup alignment (Provisional) |
| D14 | Pilotability & Error Tolerance | 30 | Link climb requires 4–6 summon steps and targeting triggers; moderate pilot error risk; no error-tolerance data; complexity ~6/10 (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 36, Going First ≈ 42, Going Second ≈ 41, Meta = provisional, Tournament Reliability ≈ 28. Modifiers: Illegality (Maxx "C" + Extra Deck oversized) (-18); Missing core cards (23/25 meta-standard absent) (-10); No combo evidence + no side deck (-6). Final formula: Structural capped due to illegality (Maxx "C" Forbidden, Extra Deck 21/15); no reliable metagame — Meta provisional; Final = Theoretical-only structural baseline + legality modifier
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.3 · key two-card combo ≈ 0.18 · full-brick estimate ≈ 0.35 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Searcher density (16 distinct cards with search text) provides toolbox flexibility and hand quality support
- Hand trap suite (Ash 2x, Effect Veiler 2x, Infinite Impermanence 1x) enables going-second disruption
- Recursion ecosystem via @Ignister GY recovery (Doyon, Bururu, Firewall Saber Dragon) allows multi-turn resilience
- Link climbing framework via Dark Infant, Transcode, Code Talker variants builds toward co-link board (if extra-deck legal)
- Ritual summoning option (Water Leviathan, Cyberse Magician) provides alternative win condition path
Weaknesses
- Illegal deck: Maxx "C" Forbidden in OCG; Extra Deck 21/15 oversized — cannot be played as-is
- Weak archetype purity (8% Mathmech, 40% @Ignister, 28% generic Cyberse) causes diluted engine consistency and missing meta-core cards (23 of 25 standard cards absent)
- No combo evidence supplied; median output unverified; ceiling contingent on absent cards (Firewall Singularity, Cynet Conflict, Allied Code Talker @Ignister)
- Opening-hand quality vulnerable: Magical Mallet 2x and single-copy tech suggest high mulligan/clog risk; P(brick) estimated ~35%
- Starter redundancy low: only 2 independent lines (Achichi/Pikari bootstrap vs Backup conditional); interruption recovery limited to 1–2 follow-ups
- Resource economy cost-heavy: Backup discard, A.I. Meet You LP cost, Cynet Mining mill — net advantage per turn marginal
- No side deck (0/15); post-side strategy unknown and unevaluable
- Tournament context absent; archetype meta-share and matchup performance unknown
Critical choke points
- Maxx "C" and Extra Deck violations — deck is illegal and cannot be played in official OCG events
- Missing Firewall Dragon Singularity, Cynet Conflict, Allied Code Talker @Ignister — these are 100% inclusion in meta-standard lists; their absence caps combo ceiling and board interaction quality
- Starter redundancy: if first @Ignister/Mathmech search is negated (Ash, Effect Veiler, Called by the Grave), very limited secondary lines exist; resilience drops sharply
- No recursion for Extra-Deck bosses (Firewall Dragon, Accesscode Talker, etc.); if summoned and removed, retrieval difficult
- Ritual Summoning dependency on Cynet Ritual or A.I.'s Ritual; both are once-per-turn and resource-intensive; alternative summon method unclear
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Maxx "C" (Forbidden in OCG) | Any legal hand trap or tech card (e.g., Ghost Ogre & Snow Rabbit, Droll & Lock Bird, or Dimension Shifter) | Maxx "C" is Forbidden; replacing with a legal hand trap maintains disruption while restoring legality |
| 2 | 3–6 Extra Deck cards (currently 21/15 oversized) | Prioritize meta-standard flex slots: Cynet Conflict (1x), Firewall Dragon Singularity (1x), Allied Code Talker @Ignister (1x), Droll & Lock Bird (1x), Harpie's Feather Duster (1x); consider cutting redundant variants (e.g., one Firewall Dragon Dark Fluid copy) | Extra Deck illegality; meta-core cards are 100% inclusion in competitive lists and will dramatically improve combo ceiling and board quality |
| 3 | Magical Mallet 2x | Upstart Goblin (1x) or One Day of Peace (1x) to smooth 46-card main deck and reduce hand clog | Magical Mallet suggests mulligan risk; deck is 6 cards over optimal 40-card main and hand quality is vulnerable |
| 4 | A.I. Meet You, FA.I.ghting Spirit (1x each) if they do not support the primary line | Cynet Conflict or other meta-tech to improve going-second interaction | Both are LP-cost and searcher-dependent; if not core to combo, redirecting slots to meta-standard board breakers will improve going-second power |
| 5 | No side deck present | Construct a 15-card side deck with anti-meta tech (e.g., 2–3 Droll & Lock Bird, 2 Harpie's Feather Duster, 1 Red Reboot, hand trap variants) | No post-side plan exists; best-of-3 play requires side deck construction for consistency across games |
Evidence & confidence
- Verified: Legality status: Illegal (Maxx "C" Forbidden, Extra Deck 21 > 15); Deck size: Main 46, Extra 21, Side 0; Archetype: Mathmech (exact-name 7 copies, 10.4% purity); Format: OCG; Card text: all 67 distinct cards resolved and confirmed; Copy histogram: 28 singles, 3 doubles, 4 triples; Usage statistics: 8% core present (2/25 meta-standard cards in deck); Role tag counts: 6 hand traps, 8 tech, 16 searchers, 12 negation text, 15 removal text
- Observed: P(≥1 @Ignister in hand 5) ≈ 0.68 via hypergeometric (12 @Ignister copies); P(≥1 hand trap in hand 6 going-second) ≈ 0.59 (6 hand traps in 46-card main); Searcher density: 16 distinct cards with 'searcher' role hint; 0.35 of main deck; Extra Deck composition: 16 Link, 2 XYZ, 2 Synchro, 1 Fusion (16 Link-heavy, suited for climbing)
- Inferred: Opening-hand quality: P(brick, no starter, no hand trap, no searcher) ≈ 0.35 (Inferred); Combo ceiling: ~65 power index if legal and fully assembled with meta-core cards (Firewall Singularity, Allied Code Talker, Cynet Conflict); heavily contingent on absent cards (Inferred); Median output: ~50–55 on sub-optimal lines and without meta-core cards present (Inferred); Interruption resilience: ~2–3 independent lines before choke point (Inferred from starter redundancy and recursion text); Resource economy: net advantage per turn estimated neutral to slightly negative due to Backup discard, A.I. Meet You LP cost, Cynet Mining mill (Inferred); Going-first board: 2–4 negations/removal pieces via Firewall/Transcode/Dark Templar; interaction_density ~2.5 (Inferred); Going-second power: moderate (6 hand traps + Cyberse Desavewurm board breaker); effectiveness contingent on breaching opponent board (Inferred); Pilotability: ~6/10 complexity; link climbing 4–6 steps, multiple targeting triggers; moderate pilot error risk (Inferred)
- Provisional: Meta Power: null — no dated metagame sample supplied; archetype meta-share unavailable (tournament_context.available = false); Matchup performance: unknown — no tournament link, no per-pilot match record, no win-rate telemetry; Post-side plan: unknown — no side deck present (0/15)
- Data gaps: No combos supplied: combos_evidence.total_combos = 0; combo floor, median, and ceiling are text-inferred only No tournament context: archetype meta-share, per-pilot match record, and format placement unknown No side deck: post-side strategy unevaluable No win-rate telemetry: going-first/going-second win rates, matchup outcomes, brick rates, and OTK frequency unknown No guide evidence: strategic intent and pilot notes absent; archetype meta-positioning unknown Legality violations prevent competitive evaluation: deck cannot be scored normally until Maxx "C" and Extra Deck are corrected
