Legality
Main 44 / Extra 14 / Side 0 — status: Legal.
Identity & game plan
- Win condition: R.B. Link and Machine boards (Brute Blues, Shepherd's Crook, Machina Citadel 3000 ATK, Night Train 2500 ATK) pressure through 2-card and 3-card R.B. starters; Sky Striker and Train link/Machine bodies as extra attackers when the R.B. core is thin
- Turn 1 (going first): Open Stage Landing or Funk Dock, add or summon an R.B. monster, build a Link 2 or 3 board, and hold Forbidden Droplet or Crown for the first opposing response
- Turn 2 (going second): Use Ash Blossom and Forbidden Droplet in response to the opponent's first line, then convert the surviving R.B. monster into a Link board
- Recovery: Rebuild from the GY and banish zone through Lambda Cannon (GY add), Stage Landing (banish replacement), and Scrap Recycler (shuffle-draw from GY)
- After siding: Not defined: the list has no side deck, so there is no post-side plan in the evidence
Why it scores here
The deck reliably opens its R.B. core: 26 archetype-core copies give about 99% at-least-one-in-opening-hand (Inferred), and Stage Landing, Funk Dock and Exceptional Schedule each have 3 copies. Its interaction density is high on paper, with 3 Ash Blossom, 3 Forbidden Droplet, 3 Forbidden Crown and R.B. Next Phase, which earns the D7 score on the system rather than on individual cards. Conversion and median output are inferred from text only because no recorded boards exist, so D3 and D4 stay moderate. Scores are reduced for the 22-spell, 20-monster main deck with conditional summon restrictions, the absence of any side deck (D12), and a Sky Striker link branch that has no main-deck Ace monsters to feed it. Popularity and usage data confirm the list is a real, accessible R.B. build but did not add points, and card scores were not averaged into the deck score.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 72 | P(at least one starter in 5) about 0.31 per 3-copy starter, archetype core P(open at least one) 0.992; starter density is high (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 22 spells and 20 monsters with several hand-only Special Summons gated on the field state, so some hands go dead on empty or wrong boards (Inferred) |
| D3 | Combo Conversion & Ceiling | 58 | No recorded boards; ceiling inferred from R.B. chains and Link 3 boards with Brute Blues and Shepherd's Crook (Inferred) |
| D4 | Combo Floor & Median Output | 48 | No recorded boards; median output unknown and Sky Striker links depend on an unverified token material path (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 62 | Ash x3, Droplet x3, Last Stand, Next Phase and banish-replacement recursion give several independent routes after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Pot of Sloth, Scrap Recycler shuffle-draw and Lambda Cannon GY recovery give draw and recursion; no resource telemetry (Inferred) |
| D7 | End-Board & Interaction Quality | 72 | Negation text 15 and removal text 16 across 25 distinct main cards, with 9 Ash or Droplet or Crown copies (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 62 | Hand-trap hit on 6-card hand 0.363 for 3 Ash; Forbidden Crown and Night Train 2500 ATK give going-second board pressure (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Night Train 2500 ATK, Machina Citadel 3000 ATK and Link 3 bodies give closing power, but no end-board telemetry (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 58 | 44 main cards, 25 distinct, 19 of 25 run at 3 or 1 copy; several low-role 1-of cards and 3-of Pot of Sloth reduce compactness (Verified structure, Inferred efficiency) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 14 Extra cards, 10 distinct: Link 2 and 3 R.B. and generic Link, one Synchro and Sky Striker links with no main-deck Ace monsters (Verified structure, Inferred) |
| D12 | Side Deck Adaptability | 20 | No side deck (0 of 15 allowed) so no post-side adaptability is evidenced (Verified absence) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament link and no dated metagame sample; archetype context only (Provisional) |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step conditional summons, Quick Effects and banish-replacement timing are complex; moderate error tolerance (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 58.6, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Engine conflict (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.31 · 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
- Archetype core is nearly always accessible (26 core copies, 0.992 in opening 5)
- Negation and removal coverage across 25 distinct main cards, with 9 Ash/Droplet/Crown copies
- Several independent recovery routes: Lambda Cannon, Stage Landing banish, Scrap Recycler shuffle-draw
Weaknesses
- No side deck, so no post-side adaptability
- Sky Striker link branch is weakly fed by the main deck
- Many conditional summons and field-state restrictions (Ga10 series, Mulcharmy) raise the brick and misplay rate
Critical choke points
- R.B. monster needed for Stage Landing and Funk Dock targets
- Field-state gate on hand-only Special Summons (empty or R.B.-only field)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 0 cards (no side deck exists) | Add a 10-15 card side deck | Side count 0 is legal but leaves D12 at 20 and gives no post-side plan |
| 2 | 1-2 Pot of Sloth | 1 hand-trap or board-breaker from the side deck, once a side deck exists | Pot of Sloth is a 3-copy draw card that does not progress the R.B. board on its own; the replacement adds interaction |
| 3 | 1-2 Mulcharmy Fuwalos | 1 Stage Landing or Funk Dock copy (already 3) or a R.B. monster from the Deck | Mulcharmy only works with an empty board, so it conflicts with the R.B. field-presence plan |
Evidence & confidence
- Verified: Deck is legal: 44 main, 14 extra, 0 side; Sky Striker Mecha - Hornet Drones is Limited at 1 copy; Card counts and archetype spread from the evidence pack; Probabilities from the hypergeometric table
- Inferred: Opening-hand consistency for the R.B. core (D1, D2); Interaction density from card text (D7); Going-first and going-second estimates (D8, D9); Recovery routes (D5, D6)
- Provisional: Meta power (null, no dated sample); Matchup and format fit (D13)
- Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: meta-share and per-pilot match record absent no win-rate telemetry for going-first, going-second, matchup or brick rate usage_statistics in_this_deck flags are false for Dawn Dragster, Camellia, Kagari, Amatsu, Hayate and Shepherd's Crook, which appear in the cards list, so the missing_core list and core_present_pct (64) are unreliable for the Extra Deck no side deck: post-side plan and D12 are evidence-free Meta Power is provisional unless a dated metagame sample is supplied
