Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Synchro Summon a Stardust, Majestic Star, or Draco-Equiste finisher from a tuner plus non-tuner board; Disruption (negation and removal text) into a Synchro board
- Turn 1 (going first): Normal Summon a tuner (Quickdraw Synchron, Debris Dragon, or Junk Synchron), use Tuning to search a Synchron tuner if needed, then Synchro Summon a boss
- Turn 2 (going second): Use Scrap-Iron Scarecrow, Power Frame, or Graceful Revival for interaction, then rebuild a Synchro board from the Graveyard
- Recovery: Recycle the Graveyard through Junk Synchron, Quillbolt Hedgehog, and Graceful Revival; Reinforcement of the Army and Tuning search replacement tuners
- After siding: Not evaluable: the deck runs no Side Deck cards
Why it scores here
The deck reliably opens a tuner in its opening hand about 64% of the time when going first (7 tuners in 40 cards, hypergeometric, Inferred), so the Synchro engine is usually live by turn 2. Tuning and Reinforcement of the Army add some search, but there is no hand trap and no floodgate, and the recorded-combo evidence is absent, so conversion and median output are text-only estimates. Interaction is broad on paper (9 negation and 8 removal text hits), but it is spread across weak one-shot traps and Scarecrows rather than layered boss-level protection. Closing power is the strongest axis because the Extra Deck holds 3000-3800 ATK Synchros and a Fusion finisher. The score is not earned from Synchron's popularity or from averaging card scores; it reflects the system, and it is capped down because the list runs Level Eater, which is Forbidden in Master Duel, so the evaluation is theoretical and structural only.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least one of 7 tuners in a 5-card opening hand) ≈ 0.64; 2-card bootstrap via Tuning (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | No garnets; redundant tuners and several dead-on-hand traps and Scarecrows (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | No recorded boards; ceiling read from Stardust, Majestic Star and Draco-Equiste card text (Inferred) |
| D4 | Combo Floor & Median Output | 45 | No recorded boards; median likely lower than ceiling given 1-copy Level Eater dependence and bricks (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 50 | Multiple tuner routes and Graceful Revival/Junk Synchron recursion, but a single Extra-Deck chokepoint per line (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Graveyard recursion via Junk Synchron, Quillbolt Hedgehog and Graceful Revival; Tuning and Reinforcement of the Army search (Inferred) |
| D7 | End-Board & Interaction Quality | 55 | 9 negation and 8 removal text hits, no hand traps, most interaction is one-shot traps and Scarecrows (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 40 | Going-second plan leans on traps and Scarecrows with no hand traps and no board breakers beyond Stardust (Inferred) |
| D9 | Offensive Pressure & Closing Power | 65 | Road Warrior 3000, Draco-Equiste 3200, Majestic Star Dragon 3800 ATK finishers (Verified stat, Inferred closing) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 40 main cards, 29 distinct, 53 off-archetype copies; Synchron purity is low (Verified count, Inferred coherence) |
| D11 | Extra Deck Efficiency & Coverage | 50 | 14 Synchro and 1 Fusion Extra-Deck cards; mix of mandatory and flex boss slots (Verified count, Inferred flexibility) |
| D12 | Side Deck Adaptability | 10 | Zero Side Deck cards; no post-side plan is possible (Verified) |
| D13 | Matchup Coverage & Format Fit | 45 | No tournament link and no dated meta sample; Meta Power provisional (Provisional) |
| D14 | Pilotability & Error Tolerance | 60 | Synchro sequencing with tuner and Extra-Deck choices is moderate; several decision points (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 52, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(50) + 0.20*TournamentReliability(45) = 49; banlist-exposure modifier -12 (Illegal list, Level Eater Forbidden) => 37. Theoretical/structural only.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.64 · 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
- Tuner density (7) keeps Synchro summons reachable in the opening hand
- Strong Extra-Deck finishers at 3000+ ATK
- Graveyard recursion through Junk Synchron, Quillbolt Hedgehog and Graceful Revival
Weaknesses
- Level Eater is Forbidden in Master Duel, so the list is illegal
- No hand traps or floodgates; going-second interaction relies on one-shot traps
- Zero Side Deck cards
- Low Synchron purity (3.6% exact-name, 53 off-archetype copies)
Critical choke points
- Tuner availability: 7 tuners in 40 cards, and the Synchro line stops without one
- Single Extra-Deck boss per line
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Level Eater (57421866) | A legal Level 1 or lower tuner or an extra Synchron tuner | Removes the only Forbidden card, making the list legal and removing the illegal-deck cap |
| 2 | One Power Frame or Scrap-Iron Scarecrow copy | A Side Deck card or a hand trap | Adds a going-second answer and gives the deck a Side Deck plan |
Evidence & confidence
- Verified: Legality: Level Eater over copy limit (Forbidden); Main 40 / Extra 15 / Side 0 counts; Tuner count 7 and Extra-Deck breakdown 14 Synchro + 1 Fusion; Card stats for Road Warrior, Draco-Equiste and Majestic Star Dragon
- Inferred: P(at least one tuner in 5-card hand) ≈ 0.64; Interaction breadth and going-second plan; Dimension scores D1-D14
- Provisional: Meta Power (no dated sample); D13 matchup and 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 and matchup signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
