Junk Deck #775043 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 48/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• Format: ocg

Legality

Main 48 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro Summon Junk Warrior / Junk Warrior Extreme or a high-ATK Stardust / Quasar / Centur-Ion body from a Junk Synchron or Synchron-tuner engine; Accel Synchro Stardust Dragon and Crimson Dragon as Extra Deck boss monsters that trade up from Stardust and Junk bodies
• Turn 1 (going first): Normal Summon Junk Meister or Full-Speed Warrior to search a Junk or Synchron card, then Synchro Summon from the Extra Deck with a Tuner such as Starjunk Synchron or Scrap Synchron
• Turn 2 (going second): Hand-trap-free, so the going-second plan relies on Heavy Storm, Monster Reborn, Synchro Overtop or Synchro Chase to answer a board and then Synchro Summon a boss through the remaining Junk bodies
• Recovery: Recover from the GY with Junk Synchron, Jet Synchron, Crossroad Sonic Chick and Stardust Trail, plus Junk Meister and Full-Speed Warrior searches to rebuild the Tuner
• After siding: No side deck is registered, so there is no post-side plan in the export

Why it scores here

The deck reliably opens a Synchro plan: about 29% of going-first hands contain at least one of the three-copy searchers (Junk Meister, Starjunk Synchron, Synchro Fellowship), and 14 searcher-text cards give roughly 84% chance of at least one searcher in the opening five (Inferred, hypergeometric). Its recovery is the strongest part, with several GY-revival and re-Synchro bodies (Junk Synchron, Jet Synchron, Crossroad Sonic Chick, Stardust Trail) keeping the Tuner line alive after disruption. Its closing power is high because the Extra Deck runs several 2500 to 4000 ATK bosses, but the single Junk Synchron gates the Junk Warrior lines, and the deck has no hand traps and only four Limited one-of answers, so interaction is thin. The score comes from the system: engine access, recovery, and closing power against brick risk, a sub-archetype spread of 22% exact-name purity, and a missing side deck. It is not from popularity, and the card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: No side deck (-3); Single-copy Junk Synchron choke (-2); Engine conflicts across sub-archetypes (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 55.6 before modifiers, -8 modifiers, rounded to 48

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.29 · 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

• Searcher density: 14 searcher-text cards support the engine across both going-first and going-second hands
• Revival and tuner redundancy: multiple GY recursion routes keep a Synchro line alive after disruption
• High closing power: several 2500 to 4000 ATK Extra Deck bosses
• Legal at full copy limit for the four Limited cards

Weaknesses

• No hand traps and no floodgates; interaction is limited to a few one-of answers
• Single Junk Synchron gates the Junk Warrior lines
• No side deck for best-of-3 adaptation
• Mixed sub-archetypes reduce engine coherence (22.2% exact-name purity)

Critical choke points

• Junk Synchron (1 copy) as the required Tuner for Junk Warrior and Junk Warrior Extreme
• Going-second hands with no searcher or Tuner will not reach a Synchro Summon without a GY trigger

Recommended changes

Evidence & confidence

• Verified: Legality: Legal, 48 Main / 15 Extra / 0 Side within OCG size rules; Limited one-ofs: Harpie's Feather Duster, Heavy Storm, Monster Reborn, T.G. Hyper Librarian; Extra Deck ATK and level values from the card list
• Inferred: Going-first and going-second consistency from hypergeometric odds; Synchro sequencing and recovery read from card text; Interaction density from text role hints
• Provisional: Meta Power (null); Matchup and format fit (D13)
• Data gaps: No recorded combos, so the floor, median and ceiling are text-only inferences No tournament link, so archetype meta-share and per-pilot records are absent No win-rate telemetry for going-first, going-second, matchup or brick rates Meta Power is Provisional without a dated metagame sample Usage statistics mark Junk Speeder, Crimson Dragon, Scrap Warrior, Stardust Dragon, Accel Synchro Stardust Dragon and Stardust Dragon - Victim Sanctuary as absent (in_this_deck false), but all six appear in the Extra Deck card list; core_cards_present (11 of 21) is probably undercounted and was not used for scoring
