Junk Deck #760920 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Junk Synchron and Synchro Dragon board building through Synchro Summons from the Extra Deck (Junk Speeder, Stardust Dragon, Shooting Majestic Star Dragon, Red Supernova Dragon); Interaction-backed grind: hand traps and Synchro negates protect the Synchro board and punish the opponent's first summon
• Turn 1 (going first): Normal Summon Junk Meister or Starjunk/Jet Synchron to search Junk material, then build a Synchro Summon; Junk Signal or Mulcharmy draws add redundancy. Forbidden cards cannot be legally run, so the plan is theoretical only.
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Droll and Ghost Ogre to answer the opponent's first summon or search, then Synchro Summon once the board is open. Forbidden and over-limit cards cannot be legally run.
• Recovery: Recur Junk or Synchron monsters from the GY through Junk Armor, Jet Synchron and Starjunk Synchron effects, then re-Synchro Summon. Recovery depends on Junk Synchron's Level 2 or lower GY target, which is partly theoretical.
• After siding: No side deck is registered (side_count 0), so there is no post-side plan and no sideboard adaptation.

Why it scores here

The deck is Illegal in OCG: five cards exceed their copy limits, including three Forbidden cards (Called by the Grave, Triple Tactics Talent, Crystal Wing Synchro Dragon), so it receives no normal Final Contextual score and is capped low as a theoretical, structural-only read. Structurally, the Junk core (18 archetype-core copies, about 87% chance of at least one in a 5-card opening hand per the hypergeometric estimate, Inferred) gives reasonable engine access, and 15 hand-trap or negate-text cards give good going-second interaction. The main weaknesses are low archetype purity (about 16% exact-name Junk cards, with Mulcharmy, Stardust, Synchron, Scrap, Rose and Genex sharing the slots), a 55-card main with 33 distinct cards, and no side deck. No combo boards were supplied, so floor, median and ceiling are text-only inference. Popularity and archetype usage stats confirm the list is real but did not add points; card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: 0.8 Combo / 0.2 Toolbox (disclosed; Structural only, not used for final score because the deck is illegal). Structural ≈ 50, Going First ≈ 48, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Illegal legality cap (-23); No side deck (-3); Low archetype purity (-2). Final formula: Illegal deck: theoretical structural read only (0.80*Structural + 0.20*TournamentReliability = 48), then capped to 25 for illegal copy limits and Forbidden cards; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.87 · key two-card combo ≈ — · full-brick estimate ≈ 0.13 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• 18 archetype-core copies give high opening access to the Junk engine (Inferred)
• 15 hand-trap or negate-text cards and many removal-text cards provide layered interaction (Inferred)
• Extra Deck has 15 Synchro finishers with strong ATK options (Verified card data)

Weaknesses

• Illegal in OCG: three Forbidden cards and two over-limit cards (Verified)
• Low archetype purity (about 16%) and a mixed multi-archetype engine (Verified composition)
• No side deck registered, so no adaptation (Verified)
• No combo data, so the ceiling and median are unmeasured (Verified gap)

Critical choke points

• Junk Synchron and Junk Meister as the first Synchro material source
• Dependence on Forbidden or over-limit cards that cannot be legally played

Recommended changes

Evidence & confidence

• Verified: Illegal status: 3 Forbidden cards, 2 over-limit cards (legality); Main 55, Extra 15, Side 0 (legality); Archetype purity about 15.7% (composition); 15 Synchro cards in the Extra Deck (composition)
• Inferred: P(at least one Junk core card in hand of 5) ≈ 0.87 (probabilities); Hand-trap odds ≈ 0.87 going second (probabilities); Engine access and interaction scores (Inferred from card text)
• Provisional: Meta power and matchup fit (no dated metagame sample)
• Data gaps: no combos supplied, so combo floor, median and ceiling are text-only inference no tournament link, so archetype meta-share and per-pilot match record are absent no win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied no side deck is registered
