Bystial/Byssted — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (±5 · Confidence: Medium)
| Overall score | Value |
|---|---|
| Structural Deck Power | 56 |
| Going First | 60 |
| Going Second | 55 |
| Meta Power | provisional |
| Tournament Reliability | 30 |
- Primary strategy: Combo
- Secondary strategies: Midrange
- Format: ocg
Legality
Main 50 / Extra 20 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: DARK Dragon Link board pressure with interruption; Bystial GY removal and hand-trap lock
- Turn 1 (going first): Open Rokket/Bystial starter, build Borrelend/Borrelsword board with negation layers
- Turn 2 (going second): Use Ultimate Slayer/Super Polymerization/Crossout to break board and swing
- Recovery: Recur Rokket monsters via Recharger/Pisty and float effects
- After siding: No side deck present; cannot adapt post-side
Why it scores here
This deck is flagged Illegal because its Extra Deck contains 20 cards while the OCG format caps at 15, so it cannot be played in a sanctioned event and receives a capped theoretical evaluation rather than a normal Final Contextual score. The underlying system is a Rokket/Bystial Dragon combo build that can open with multiple starters (Rokket Loader, Quick Launch, Dragon Shrine) and convert into DARK Dragon Link boards with interaction from hand traps and Bystial removal. Consistency is moderate (P≥1 core starter ≈0.60 Inferred) but the list runs many one-ofs and Limited staples that thin redundancy, and no parsed combo logs exist to confirm median output. Popularity of Bystial/Rokket archetypes did not earn points; the score reflects system cohesion under illegal construction, not card averages.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 60 | Hypergeometric P(≥1 archetype-core starter in 5) ≈0.60 from 8 copies; multiple 3-copy starters present (Inferred). |
| D2 | Opening-Hand Quality & Brick Management | 55 | Copy histogram shows 20 singles and 8 triples; many garnet-like one-ofs increase brick risk (Inferred). |
| D3 | Combo Conversion & Ceiling | 70 | No parsed combos; text suggests ceiling with Borrelend/Draco Berserker boards but unconfirmed (Inferred). |
| D4 | Combo Floor & Median Output | 50 | Median output unknown due to zero scored combos; floor assumed modest with 2-card lines (Inferred). |
| D5 | Interruption Resilience & Route Redundancy | 50 | Key Bystial and staples at Limited copies reduce route redundancy after disruption (Inferred). |
| D6 | Resource Economy, Recovery & Grind | 55 | Rokket Recharger and Guardragon Pisty enable GY recursion; resource signature moderate (Inferred). |
| D7 | End-Board & Interaction Quality | 70 | Role tags show 11 negation-text and 18 removal-text cards; hand traps + Impermanence layer interaction (Verified flags). |
| D8 | Going-Second & Board-Breaking Power | 60 | Ultimate Slayer, Super Polymerization, and Crossout provide going-second tools but extra size illegal (Inferred). |
| D9 | Offensive Pressure & Closing Power | 60 | Extra Deck contains 3500-ATK Borrelend and 3000-ATK bosses for closing pressure (Verified stats). |
| D10 | Main Deck Efficiency & Flexibility | 50 | Main deck 50 cards with 31 distinct; some off-archetype splash reduces compactness (Inferred). |
| D11 | Extra Deck Efficiency & Coverage | 40 | Extra Deck 20 cards (illegal) with 13 Links; many mandatory combo pieces but over limit (Verified count). |
| D12 | Side Deck Adaptability | 0 | Side Deck is empty (0 cards) so post-side adaptability cannot be evaluated (Verified). |
| D13 | Matchup Coverage & Format Fit | 50 | No dated metagame sample; matchup fit provisional from archetype context only (Provisional). |
| D14 | Pilotability & Error Tolerance | 40 | Combo lines require multiple Link climbs and material management; error tolerance moderate-low (Inferred). |
How the score was computed
Strategy profile: Combo. Structural ≈ 56, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: illegal_extra_deck_size (-30). Final formula: Illegal deck: theoretical structural-only evaluation capped low; normal formula not applied
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.6 · key two-card combo ≈ — · full-brick estimate ≈ 0.4 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Diverse Dragon Link extra deck options
- Good hand trap density (Ash, Impermanence, Droll, Mulcharmy)
Weaknesses
- Illegal extra deck size (20 > 15)
- Many one-of copies reduce consistency
- No side deck for best-of-3 adaptation
Critical choke points
- Limited Bystial copies (Magnamhut, Druiswurm at 1)
- Extra deck over limit prevents legal play
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 5 Extra Deck cards (reduce from 20 to 15) | Meet OCG extra deck size limit to make deck legal |
Evidence & confidence
- Verified: Legality status Illegal; Card text excerpts; Banlist statuses (Limited/Semi-Limited); Extra deck count 20
- Inferred: Opening starter probability; Brick risk from singles; Ceiling boards from text
- Provisional: Matchup format fit
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
