Legality
Main 53 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Synchro boss from the Extra Deck (Clear Wing / Stardust / Crystal Clear Wing lines, 2500-3500 ATK) after a Speedroid or Roid searcher opens the Tuner; Hand-trap-protected board of Synchro monsters that negate or destroy the opponent's answers
- Turn 1 (going first): Speedroid searcher (Terrortop, Darumaknocker, Marble Machine) into a Tuner and a Synchro, using Speedroid Scratch or Wynn to refill
- Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre and Droll & Lock Bird for the opponent's first search or summon, then convert the surviving resources into a Synchro
- Recovery: Speedroid Dupligate and Clear Wing Wonder recover from the GY; Mulcharmy draws refill the hand when the board is empty
- After siding: Not evaluable: the side deck is empty (0 cards), so there is no post-side plan
Why it scores here
This list cannot receive a normal score because it is illegal: Ash Blossom & Joyous Spring runs 3 copies against an OCG Semi-Limited limit of 2, and the score is capped low and treated as structural only. Structurally, the deck reliably gets to a searcher and a Tuner: about 80% of 5-card hands hold at least one of the 14 searcher-text cards, and the Extra Deck of 13 Synchro monsters and 1 Link gives it several boss options. Its strongest structural feature is interaction: 12 hand traps and 19 negation-text cards give it a good going-second answer density. The deck does not earn points for popularity, since the usage data shows Mulcharmy Fuwalos and Droll & Lock Bird only, and it does not earn points from the archetype label, which matches no card. The score came from consistency, interaction and Extra Deck coverage on the system, not from averaging the card scores. Without recorded boards there is no measured combo floor or ceiling, so those dimensions stay Inferred and pulled down.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one searcher text card in a 5-card opening hand) ≈ 0.80 across 14 cards; Tuner access depends on 16 Tuner monsters but the Synchro boss needs both pieces (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 12 hand traps and 15 tech cards in the Main Deck create many dead cards without a board; P(at least one hand trap in a 6-card going-second hand) ≈ 0.80 (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No parseable boards; the Clear Wing and Stardust bosses give high ceilings on text alone, so the ceiling is an Inferred text read, not a measured value (Inferred) |
| D4 | Combo Floor & Median Output | 45 | combo data is empty (0 boards), so the median and floor cannot be measured and are estimated only from starter diversity (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Two or more starter types (Speedroid, Roid, Mulcharmy, Charmer) and recursion from Dupligate and Clear Wing Wonder give some redundancy after disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Speedroid Scratch, Wynn and Mulcharmy draw cards back up after spending, but the GY recursion is narrow and the Extra Deck is one-shot (Inferred) |
| D7 | End-Board & Interaction Quality | 75 | Ash Blossom, Ghost Ogre, Ghost Belle, Droll & Lock Bird, Infinite Impermanence, Dominus Purge and Synchro Emergency give layered interaction; 19 negation-text and 23 removal-text cards in the list (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 72 | Going-second hand traps (P ≈ 0.80 in a 6-card hand) and Clear Wing negation effects challenge an established board, but there is no going-second win-rate data (Inferred) |
| D9 | Offensive Pressure & Closing Power | 58 | Crystal Clear Wing Over Synchro Dragon (3500 ATK) and Clear Wing Synchro Dragon (2500 ATK) close the game, but only 2 and 2 copies with no measured end-board data (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 53 Main Deck cards with 26 distinct cards: 12 cards at 3 copies, with many 1-of Speedroid tech cards, so the Main Deck is spread across too many roles (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 65 | 13 Synchro and 1 Link in the 14-card Extra Deck give full coverage of the Synchro bosses, with mostly WIND-compatible Tuners (Verified structure, Inferred use) |
| D12 | Side Deck Adaptability | 10 | The side deck is empty, so there is no adaptability for best-of-3 play (Verified, 0 cards) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament or dated metagame sample; archetype share is unavailable, so this stays Provisional at neutral 50 |
| D14 | Pilotability & Error Tolerance | 40 | Many Speedroid summoning conditions, Normal-Summon restrictions and 5+ hand-trap timings make the list demanding to pilot, with a high decision count (Inferred) |
How the score was computed
Strategy profile: Midrange primary; Stun secondary used only as the reason for the hand-trap weighting in the rationale (not as a blended weight set). Structural ≈ 56, Going First ≈ 50, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); engine conflict (-3); illegal_list_cap (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*56 + 0.20*45 = 53.8; modifiers -12 (banlist), -3 (engine conflict), -4 (illegal-list cap) = 34.8 -> 35
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.8 · 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
- Layered hand-trap and negation density (12 hand traps, 19 negation-text cards) gives strong going-second interaction
- 13 Synchro bosses plus a Link in the Extra Deck give boss coverage across several WIND Tuner lines
- Searcher density (14 cards) gives about 80% chance of a searcher in an opening 5-card hand
Weaknesses
- Illegal copy count on Ash Blossom & Joyous Spring (3 vs 2)
- Empty side deck: no best-of-3 adaptation
- Off-archetype spread (67 of 94 copies) weakens engine coherence
- No recorded boards, so the combo floor and ceiling are text-only
Critical choke points
- The Ash Blossom copy count must be fixed before the list can be played in OCG; the copy limit is the first choke point
- Tuner access: 16 Tuners, but the Synchro boss needs a specific Tuner plus a non-Tuner, so a hand with a searcher and no Tuner stalls
- Going-second hands with no hand trap give the opponent a free first turn
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | one copy of Ash Blossom & Joyous Spring | one non-Ash interaction card (for example a 1-of hand trap or a second Droll & Lock Bird-style card if legal) | Brings the list inside the OCG Semi-Limited limit so the normal score can apply |
| 2 | one 1-of Speedroid tech card with no searcher or Tuner text | one more searcher or Tuner monster | Reduces the Synchro access gap and improves Tuner access in the opening hand |
| 3 | none | a side deck of 15 cards | The list has no side deck, so it has no best-of-3 plan; a side covering the most common hand traps is needed |
Evidence & confidence
- Verified: Ash Blossom & Joyous Spring runs 3 copies against an OCG Semi-Limited limit of 2; Main Deck is 53 cards and Extra Deck is 14, both inside the OCG size rules; Side deck is empty (0 cards); Extra Deck contains 13 Synchro and 1 Link monsters; Usage data shows only Mulcharmy Fuwalos and Droll & Lock Bird as core cards
- Inferred: P(searcher in 5-card hand) ≈ 0.80 and P(hand trap in 6-card hand) ≈ 0.80 from the hypergeometric table; Going-second hand-trap plan and Synchro boss conversion from card text; Structural dimension scores from the text-based role reads
- Provisional: Meta power and matchup fit (no dated metagame or tournament link)
- 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 are absent No win-rate telemetry exists in YGOVN for going-first, going-second, matchup or brick rates Side deck is empty, so post-side adaptability cannot be evaluated Deck title is null; the archetype label Synchron does not match any card in the list
