Deck — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (±8 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 48.5 |
| Going First | 50 |
| Going Second | 45 |
| Meta Power | provisional |
| Tournament Reliability | 40 |
- Primary strategy: Midrange
- Secondary strategies: Combo, Toolbox
- Format: ocg
Legality
Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Synchro Summon Junk/Stardust/Majestic boards (Shooting Majestic Star Dragon, Stardust Warrior, Bystial Dis Pater) after Junk Meister and Junk Synchron searches; Mulcharmy hand-advantage draw engine and Bystial banish-to-summon boards
- Turn 1 (going first): Open Junk Meister or Junk Synchron, search Junk Synchron and Junk Warrior/Synchro enablers, Synchro Summon into a Junk or Stardust boss while holding Ash Blossom and Droll as protection (plan is text-only, not observed)
- Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Nibiru and Mulcharmy hand-traps to answer the opponent's first summon chain, then rebuild through Mulcharmy draws and Synchro Summons (text-only inference)
- Recovery: Junk Synchron and Starjunk/Scrap Synchron recursion from GY, Mulcharmy draws off the opponent's summons, and Junk Armor/Junk Speeder rebuild the Synchro field (Inferred)
- After siding: Not evaluable: side deck is empty (0 cards) and the list is OCG best-of-3 compatible only with a side plan, so the post-side plan is absent
Why it scores here
The deck reliably opens a Junk or Stardust starter only about one time in four in the opening five (Junk Meister P(at least one) 0.25 at three copies; core-group proxy 0.76 Inferred), so the engine's accessibility is moderate rather than strong. Its interaction density is high (seven hand traps, Solemn Judgment, Ash Blossom, Droll, Nibiru, Synchro Zone and several Synchro negation effects) and its closing boards (Shooting Majestic Star Dragon, Stardust Warrior, Bystial Dis Pater) are strong, which earns the interaction and closing dimensions. Floor and median output, combo ceiling and going-second board-breaking are all text-only inferences because no recorded boards exist, so they are scored conservatively. Popularity was not credited (the archetype usage stats confirm a real Junk core but do not raise power), and card scores were not averaged into the deck. Four copy-limit and banlist violations make the list illegal, so the final score is capped at 25 and the result is theoretical/structural only, with the structural score of 48.5 shown for reference.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(at least one Junk Meister in hand of 5) = 0.25; archetype core group P(at least one) = 0.76; 2-card bootstrap via Junk Synchron and Junk Meister (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | Seven hand traps, 17 tech cards and several dead-in-hand cards (Called by the Grave, Triple Tactics Talent, Harpie's Feather Duster) raise brick risk; 21 of 34 distinct main cards are singletons (Inferred) |
| D3 | Combo Conversion & Ceiling | 50 | No parseable boards; ceiling read from card text only (Shooting Majestic Star Dragon, Stardust Dragon, Bystial Dis Pater boards) (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded combos, so median and floor are unmeasured; Junk line depends on Extra Deck Synchro access and Warrior/Stardust enablers (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Multiple independent starters (Junk Meister, Mulcharmy draws, Synchron recursion) and several negations give redundancy after one interruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 50 | Mulcharmy draws, Junk Synchron GY recursion and Stardust returns regenerate cards; Reinforcement of the Army and Synchro Fellowship add searches (Inferred) |
| D7 | End-Board & Interaction Quality | 58 | Ash Blossom, Droll & Lock Bird, Solemn Judgment, Synchro Zone and Stardust Dragon negation text give layered interaction (Inferred semantic read) |
| D8 | Going-Second & Board-Breaking Power | 55 | Going-second relies on hand traps and Bystial banish-to-summon boards; no going-second split is available (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Ends on 4000 ATK Shooting Majestic Star Dragon and 3000-3500 ATK boss Synchros; piercing and boss text present (Verified stat) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 55 main cards with 34 distinct; 24 level-0 spells/traps and 17 tech cards reduce compactness; size is within 40-60 range (Verified) |
| D11 | Extra Deck Efficiency & Coverage | 55 | Full 15-card Extra Deck with 14 Synchro and 1 Fusion (Snake-Eye Doomed Dragon needs Snake-Eye support not run); flexible but dependent on Synchro access (Verified composition) |
| D12 | Side Deck Adaptability | 10 | Side deck is empty (0 cards), so no post-side adaptability exists; scored low by construction (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link or dated meta sample; archetype usage shows a Junk core is real but meta-share unknown (Provisional) |
| D14 | Pilotability & Error Tolerance | 30 | Long Synchro chains, many optional hand-trap and negate timings and multi-card searches create high decision load (Inferred) |
How the score was computed
Strategy profile: Midrange profile, Combo secondary noted but not blended numerically. Structural ≈ 48.5, Going First ≈ 50, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-6); no_side_deck (-3); engine_conflicts (-2); legality_cap (-10.8). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*48.5 + 0.20*40 = 46.8; modifiers -11 gives 35.8; Illegal legality cap applies, final score capped at 25 (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.25 · 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
- Dense interaction package with seven hand traps and layered negation (Ash Blossom, Droll, Nibiru, Solemn Judgment)
- Strong late boards in the Extra Deck (Shooting Majestic Star Dragon, Stardust Warrior, Bystial Dis Pater)
- Draw and recursion engines (Mulcharmy, Junk Synchron) regenerate resources
Weaknesses
- Illegal list: two copy-limit overages and two Forbidden cards
- Starter access is low (Junk Meister about 25 percent in opening five)
- Zero side deck and no post-side plan
- Several dead or situational cards in the main deck
Critical choke points
- Junk Meister and Junk Synchron as the only Junk Synchro enablers
- Synchro Summon access, since the main engine is Synchro-based and Extra Deck dependent
- Ash Blossom and Droll copy limits must be corrected before any play
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave and Triple Tactics Talent | Legal tech or a third Junk starter | Both are Forbidden in OCG, so the list cannot be legal while they remain |
| 2 | One Ash Blossom & Joyous Spring and one Droll & Lock Bird | Single-copy cards or a non-restricted hand trap | Brings the list within the legal copy limits (Ash 2, Droll 1) |
| 3 | One dead-in-hand tech card (Harpie's Feather Duster) | A 15-card side deck with cards that answer the opponent's typical board | Adds post-side adaptability (D12) and removes the zero-side penalty |
Evidence & confidence
- Verified: Legality: Illegal with four copy-limit and banlist violations; Main 55 / Extra 15 / Side 0 counts and composition; Stat and level values of the listed cards; Archetype usage shows Junk core inclusion at 66 to 83 percent across sampled rows
- Inferred: Starter probability, brick estimate and interaction density; Going-first and going-second plans; Closing power from boss stat lines and text
- Provisional: Meta power and matchup fit (no dated meta sample); Tournament reliability (no tournament link)
- Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot record absent No win-rate or matchup telemetry in YGOVN Side deck is empty, so post-side is not evaluable Deck title is null in the export
