Junk Deck #760435 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro Summon large Extra Deck boss monsters (Bystial Dis Pater, Black-Winged Assault Dragon, Hot Red Dragon Archfiend Abyss) off a Junk Synchron / Stardust / Scrap tuner base; Recurring Junk and Stardust Synchro monsters through Junk Synchron, Jet Synchron and Starjunk Synchron GY effects
• Turn 1 (going first): Normal Summon Junk Synchron or Full-Speed Warrior, search a Junk or Warrior card, then Synchro Summon a boss using the tuner and recover Synchro material through GY effects
• Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Infinite Impermanence, Maxx C or Droll and Lock Bird to answer the opponent's first summon or search, then rebuild the board through Synchro Summon
• Recovery: Rebuild from the GY with Junk Synchron, Jet Synchron and Starjunk Synchron, which can each be revived or used for search after the board is cleared
• After siding: Not evaluable: the deck has no side deck (side_count 0), so there is no post-side plan

Why it scores here

The deck reliably opens a Synchro engine: the 3-copy starters have roughly a 0.25 chance of appearing in a 5-card opening hand, and the archetype core group reaches about 0.89 on at least one copy (Inferred). Interaction is dense, with 11 hand traps and 18 negation-text cards, so it can answer a first summon or search on the second player's turn. Conversion is not measured because the deck has no recorded boards, so the combo ceiling and floor are text-only estimates. Two Forbidden copies (F.A. Dawn Dragster and Baronne de Fleur) make the list Illegal, so the score is capped and the result is theoretical only. Popularity and archetype usage were not counted as power, and card scores were not averaged.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-8); No side deck (-4); Illegal cap (-8.6). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 50.6 before modifiers; modifiers -12 gives 38.6; capped to 30 because the list is Illegal (theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.89 · key two-card combo ≈ — · full-brick estimate ≈ 0.11 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense interaction: 11 hand traps and 18 negation-text cards
• Redundant Synchro tuners (Junk Synchron, Jet Synchron, Starjunk Synchron, Scrap Synchron, Assault Synchron) with GY recursion
• Strong Extra Deck bosses (Bystial Dis Pater 3500 ATK, Hot Red Dragon Archfiend Abyss, Black-Winged Assault Dragon)

Weaknesses

• Illegal: two Forbidden copies
• No side deck
• Low archetype purity (12.9 percent exact Junk) and many sub-archetypes
• No recorded boards, so the combo output is unmeasured

Critical choke points

• Synchro Summon requires a tuner plus non-tuners on the field, so a single hand-trap or removal on the board can break the line
• The Forbidden copies (F.A. Dawn Dragster, Baronne de Fleur) cannot be played in OCG, which makes the list unplayable as-is

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0; legal size range for OCG is 40-60 main, 0-15 extra, 0-15 side; Two Forbidden copies (F.A. Dawn Dragster, Baronne de Fleur) make the list Illegal; Limited cards (Maxx C, Droll and Lock Bird, Crossout Designator, Herald of the Arc Light, T.G. Hyper Librarian, Bystial Druiswurm, Bystial Magnamhut, Reinforcement of the Army) are at 1 copy, which is legal; Ash Blossom & Joyous Spring runs 2 copies, which is legal under Semi-Limited
• Inferred: Starter access is about 0.89 for the core group, from a hypergeometric estimate; Interaction density is high based on hand-trap and negation text counts; Pilotability is complex because it depends on Synchro sequencing
• Provisional: Meta power is null because no dated metagame sample is supplied; Matchup fit is unknown
• 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 are absent No win-rate telemetry for this deck; going-first and going-second splits are inferred Meta power is provisional without a dated metagame sample Deck list is Illegal, so the final score is capped and theoretical only
