Junk Deck #767719 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

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

Legality

Main 58 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro Summon a Junk Warrior or Stardust Dragon / Shooting Star Dragon style boss (4000-ATK Dragons in Extra) after Junk Synchron or Scrap/Stardust starters establish the board; Recursion through Jet Synchron, Crossroad Sonic Chick and Anchorbolt Hedgehog from the GY into repeat Synchro Summons
• Turn 1 (going first): Open a Synchron/Junk starter (Tuning, Junk Signal, Stardust Synchron, Junk Meister) to search a Junk or Synchron monster, then Synchro Summon a boss, backed by hand traps for the opponent's first response
• Turn 2 (going second): Use Ash Blossom, Ghost Ogre, Effect Veiler, Nibiru and Infinite Impermanence to disrupt the opponent's starter, then rebuild through GY recursion and Extra Deck bosses
• Recovery: Recur Synchro materials and Level 2 or lower monsters from the GY (Jet Synchron, Junk Synchron, Crossroad Sonic Chick) and use Extra Deck bosses to rebuild after a single disruption
• After siding: No Side Deck is registered, so no post-side plan exists; this cannot be evaluated

Why it scores here

The deck's Structural score of about 59 comes from consistency and interaction on the system, not from any average of card scores: a searcher-dense Synchron/Junk shell (18 searcher-text cards, about 86% chance of at least one searcher in a 5-card opening hand, Inferred) backed by 9 hand traps and 17 negation-text cards. Its ceiling is credible from the Extra Deck (three 4000-ATK Dragons and Shooting Star Dragon), but no recorded boards exist, so combo floor and median are text-only inferences and are held near neutral. Interaction and going-second strength are its clearest assets. Structural power is capped because the deck has no Side Deck and no post-side plan, and because its legal status fails. The deck is Illegal: Ash Blossom & Joyous Spring is run 3 copies against an OCG limit of 2, so the final score is capped at 35 and labelled structural-only. Archetype popularity earned no points: the Junk archetype core is present at 87.5% of its usage-stat core, and that confirms the list is real, not that it is strong.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Toolbox secondary, disclosed as 1:1 for the choice of profile; Midrange weights used for scoring. Structural ≈ 59, Going First ≈ 58, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: banlist exposure (-8); no Side Deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 0.80*59 + 0.20*50 = 57.2 before modifiers; modifiers sum to -12 giving 45.2; Illegal-deck cap applied: score = 35 (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.24 · 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 searcher text (18 cards) gives a high chance of a live hand (Inferred)
• Strong hand-trap and negation density (9 hand traps, 17 negation-text cards) (Inferred)
• Full 15-card Synchro Extra Deck with multiple 4000-ATK bosses (Verified composition)

Weaknesses

• Illegal copy limit on Ash Blossom & Joyous Spring (Verified)
• No Side Deck, so no post-side plan (Verified)
• Low archetype purity at 15%, so many generic or off-archetype cards dilute the engine (Verified)

Critical choke points

• Ash Blossom & Joyous Spring (3 copies) is the legality failure and a single-card interaction dependency
• Junk Synchron and Junk Warrior as the core engine starters; losing them removes the main line (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal (Ash Blossom & Joyous Spring, 3 copies vs OCG limit 2); Main 58 and Extra 15 are within size rules; Side 0 is legal but unadaptable; Extra Deck is 15 distinct Synchro cards; Archetype core present 7 of 8 (87.5%) in usage stats
• Inferred: Searcher and hand-trap hypergeometric probabilities; Interaction density from card text; Going-first and going-second estimates from text and probability
• Provisional: Meta Power (null, no dated metagame sample); Matchup fit and tournament reliability (no tournament link); Combo floor and median (no recorded boards)
• 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 absent no win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied No Side Deck supplied, so post-side adaptability cannot be measured Deck title is null
