Junk Deck #758582 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)

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

Legality

Main 53 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Synchro pressure from the Extra Deck (Kewl Tune B2B, Majestic Star Dragon, Bystial Dis Pater, Zalen) built off Junk Synchron and Junk Meister searches; Hand-trap and negation backup (Ash Blossom, Maxx "C", Droll & Lock Bird, Red Reboot, Herald of the Arc Light) to protect the Synchro line
• Turn 1 (going first): Open a Junk Meister or Junk Synchron starter, search the next Junk/Synchron piece, and Synchro Summon a boss; the list has no structural interaction answer to a going-first Synchro setup beyond its Limited cards
• Turn 2 (going second): Hold Ash Blossom, Maxx "C", Droll & Lock Bird and Red Reboot to disrupt the opponent's board, then rebuild through the searchers and the Synchro Extra Deck
• Recovery: Recover through the searchers (13 searcher-text cards, P at least one in hand of 5 is 0.77) and the Synchro material loop; GY-activated effects of Jet Synchron and Starjunk/Junk Synchron provide re-summons
• After siding: Not assessable: the deck has zero Side Deck cards, so no post-side plan exists in the export

Why it scores here

This deck is Illegal in the OCG format: it runs one copy each of Trishula, Dragon of the Ice Barrier and Baronne de Fleur, both Forbidden, so under the legality rule it cannot receive a normal Final Contextual score and the 20 above is a structural cap, not a competitive rating. Structurally the list has a real engine: Junk Meister (3 copies), Junk Synchron and Starjunk/Scrap Synchron feed a 15-card Synchro Extra Deck, and 13 searcher-text cards give a 77% chance (hypergeometric, Inferred) of at least one searcher in an opening hand of five. Interaction is the strongest part of the build, with Ash Blossom, Maxx "C", Droll & Lock Bird, Red Reboot and Herald of the Arc Light covering the hand and field. The score is held back by a 53-card main deck with 14.7% exact-archetype purity, six off-plan Mulcharmy and generic cards, no Side Deck, and zero recorded boards, so the floor and median are text-only inference. The popularity of the Junk core in the archetype usage stats (72% of core cards present) confirms the build is real and accessible; it did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 52, Going First ≈ 55, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Banlist exposure (-8); No Side Deck (-4). Final formula: Illegal legality cap: Structural 52 and TR 45 computed, but Final is capped at 20 and labelled theoretical/structural-only (Forbidden cards over limit); normal formula would be 0.80*Structural + 0.20*TR (Meta provisional) before modifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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

• Real Junk Synchron/Junk Meister engine with 3-copy Junk Meister and 13 searcher-text cards (P at least one in hand 0.77)
• Dense interaction package: Ash Blossom x2, Maxx "C", Droll & Lock Bird, Red Reboot, Herald of the Arc Light, Ghost Ogre & Snow Rabbit
• Full 15-card Synchro Extra Deck with high-ATK closers (Majestic Star Dragon, Kewl Tune B2B, Bystial Dis Pater)

Weaknesses

• Illegal as submitted: Trishula and Baronne de Fleur are Forbidden and over the copy limit
• No Side Deck: no adaptation across games of a best-of-3 match
• 53-card main with only 14.7% exact-archetype purity; six Mulcharmy plus generic staples dilute the engine

Critical choke points

• Junk Meister (3 copies) and Junk Synchron (1 copy) as the only Junk starters; losing them to a hand trap or a single interruption removes most of the searcher chain
• The Forbidden pair takes two Extra Deck slots that a legal Synchro closer would fill

Recommended changes

Evidence & confidence

• Verified: Two Forbidden cards (Trishula, Baronne de Fleur) run at 1 copy each with 0 legal copies; Main 53 and Extra 15 are inside OCG size rules (main 40–60, extra 0–15); Exact-name archetype purity 14.7%; 15 Synchro cards in Extra; Usage stats: 72.2% of archetype core cards present; 5 missing core cards (Crimson Dragon, Accel Synchro Stardust Dragon, Junk Speeder, Scrap Warrior, Stardust Dragon)
• Inferred: Opening-hand consistency from hypergeometric draws (archetype core P≈0.93; searcher P≈0.77); Going-first and going-second plans and board interaction read from card text; Brick risk from Mulcharmy and conditional generic cards
• Provisional: Meta power is null: no dated metagame sample; Matchup fit (D13) and tournament reliability depend on missing meta and win data
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchups, starter or brick rates Meta power is provisional without a dated metagame sample Deck has no title and no Side Deck, so post-side and naming cannot be assessed
