Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Link-summon R.B. Link monsters (Brute Blues, Shepherd's Crook, VALCan Booster) and attack with R.B. boards; closing is inferred from card text only, no recorded boards; Sky Striker Ace links (Camellia as the only realistic entry point) and Mecha Phantom Beast Tetherwolf attacks
- Turn 1 (going first): Open R.B. Stage Landing or Funk Dock to reach a Special Summonable R.B. starter, then link into a Link-3 R.B. board while holding Ash Blossom and Infinite Impermanence for the opponent's first response
- Turn 2 (going second): Use Ash Blossom, Infinite Impermanence, Droll & Lock Bird and Next Phase on the opponent's engine, then rebuild through Stage Landing or Operation Test
- Recovery: Recover R.B. monsters from the GY through Lambda Cannon, Lambda Blade and Stage Landing's banish clause; Clockwork Knight adds Clockwork Night to rebuild the Machine board
- After siding: None: the deck registers zero side cards, so there is no post-side plan
Why it scores here
This list is Illegal in OCG: it runs 3 copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of 2, so it is scored as a theoretical, structural read only and capped low. Structurally the R.B. core is reliable on paper (22 of 55 main and extra cards; about 99% chance of at least one core card in a 5-card opening hand), so engine access is the deck's strongest point. Interaction is dense (7 hand traps, 15 negation-text and 15 removal-text cards), which lifts the going-second score, and 71% of 6-card hands contain at least one hand trap. The weaknesses are on the system level: only 40% of the cards are exact R.B. names, with Sky Striker, Mecha Phantom Beast, Mulcharmy and Forbidden splashed in, and many R.B. monsters need an empty or R.B.-only field, which produces bricks. The deck has no side deck, no recorded boards and no tournament context, so popularity and archetype usage did not earn points, and no card scores were averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(at least one R.B. core card in a 5-card hand) ≈ 0.99; the 3-copy starters Stage Landing and Funk Dock give a 2-card bootstrap, but the Link-3 engines need specific materials (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | 33 of 55 main and extra cards are off-archetype, and four R.B. monsters (Ga10 Driller, Cutter, Pile Bunker, VALCan Rocket) are dead when the field has a non-R.B. monster; Mulcharmy is a conditional hand brick (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No parseable recorded boards, so the ceiling rests on text only: Link-3 R.B. boards with Stage Landing protection and a second attack from Brute Blues (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No combos supplied, so no floor or median output is measurable; the median is judged lower than the ceiling because most starters need field conditions (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Ash Blossom, Infinite Impermanence, Next Phase and Last Stand give several independent answers, but only one copy of each Droll and Hornet Drones (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | LP-cost effects (Lambda Cannon 1200, Funk Dock LP gain, Next Phase 2000 LP gain) and GY recursion (Lambda Blade, Cannon) support the grind, but the deck has no field-reset engine (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | 15 negation-text and 15 removal-text cards plus 7 hand traps; the layering is real but depends on resource-costing effects (Inferred, semantic) |
| D8 | Going-Second & Board-Breaking Power | 62 | 71% of 6-card hands contain at least one hand trap; Brute Blues and Amatsu give board-breaking reach, but the Extra-Deck link route is slow going second (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Brute Blues (1500 ATK, extra attack, cannot be destroyed by battle with an R.B. target) closes the game; the Sky Striker Aces add direct damage but are single copies (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 40 main cards with 24 distinct names and 33 off-archetype copies; the splash slots (Ash ×3, Impermanence ×3, Droplet ×3, Triple Tactics ×3) are generic tech (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 35 | 15 Link monsters across 8 distinct names; the 4 Sky Striker Aces (Hayate, Amatsu, Kagari, Camellia) need another Ace on field, and Camellia is the only one with a main-deck entry route (Inferred) |
| D12 | Side Deck Adaptability | 5 | Zero side-deck cards registered, so no post-side plan exists (Verified: Side Deck size 0) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link and no metagame sample; archetype share unavailable, so matchup fit is provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multi-step link chains, conditional field checks on several monsters, and two over-limit hand-trap decision points; a skilled pilot can run it, but the error rate is high (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 48.5, Going First ≈ 44, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Illegal copy limit (-6); No side deck (-3); Engine conflict and splash (-3). Final formula: Illegal cap applied: 0.80*Structural(48.5) + 0.20*TournamentReliability(38) + ContextModifiers(-12) = 34; Meta provisional, theoretical/structural-only
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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
- Core R.B. engine has 22 copies and reaches at least one piece in 99% of 5-card hands (Inferred)
- Seven hand traps and 15 negation-text cards give going-second interaction (Inferred)
- Link-3 R.B. Extra Deck monsters give a board-breaking ceiling (Inferred)
Weaknesses
- Illegal copy count on Ash Blossom & Joyous Spring (3 vs 2)
- Zero side deck, so no post-side plan (Verified)
- Only 40% exact archetype purity; 33 off-archetype copies dilute the engine
- Several R.B. monsters are dead on boards with non-R.B. monsters, causing bricks
Critical choke points
- Stage Landing and Funk Dock are the only main-deck R.B. starters; losing them to a hand trap leaves the Link engine without a bootstrap
- Four Sky Striker Ace Links need another Ace on field; only Camellia has a realistic route (Inferred)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | one copy of Ash Blossom & Joyous Spring | none required | Fixes the only Illegal violation; a 2-copy Ash count matches the OCG Semi-Limited limit |
| 2 | one or more off-archetype splash slots | a 15-card side deck | Gives a post-side plan and reduces the off-archetype dilution that drives the brick rate |
| 3 | Sky Striker single-copy Aces that need another Ace on field | additional R.B. Link or starter copies | Raises exact-name purity and starter reliability; Inferred from card data |
Evidence & confidence
- Verified: Deck is Illegal: Ash Blossom & Joyous Spring 3 copies vs 2 legal in OCG; Main 40 / Extra 15 / Side 0; size rules are met; Droll & Lock Bird, Sky Striker Mecha - Hornet Drones (Limited, 1 copy) and Sky Striker Mobilize (Semi-Limited, 2 copies) are within their limits; Archetype purity: 22 exact R.B. copies of 55 main and extra
- Observed: R.B. usage core present: 16 of 25 core cards included (usage stats available, 29 rows)
- Inferred: Hypergeometric opening-hand odds for starters and core cards; Hand-trap coverage and semantic negation reads from card text; Brick and dead-card rates from conditional field requirements; Going-first and going-second estimates
- Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament context)
- Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null and the deck has no side cards
