Junk Deck #769318 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · 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. 1 violation(s).

Identity & game plan

• Win condition: Junk Synchron / Jet Synchron / Starjunk Synchron engine into Synchro boss (Majestic Star Dragon, Shooting Majestic Star Dragon, Stardust Dragon, Crimson Dragon, Juraishin); Stardust and Mulcharmy draw-and-grind shell with hand traps and Solemn Judgment to protect the board
• Turn 1 (going first): Normal Summon Junk Synchron or Junk Meister to search a Junk card, then Synchro Summon a Junk or Stardust boss from the Extra Deck, protected by Ash Blossom and Ghost Ogre
• Turn 2 (going second): Hand-trap the opponent's first summon or activation (Ash Blossom, Ghost Ogre, Droll & Lock Bird), then rebuild through Junk Meister and Junk Synchron into a Synchro boss
• Recovery: Mulcharmy draw effects and Junk Meister / Junk Synchron searches refill the hand; Synchro Fellowship and Stardust Illumination recur from the GY
• After siding: Not evaluable: Side Deck size is 0, so no post-side plan exists in this list

Why it scores here

The score is capped low because the list is illegal: three copies of Ash Blossom & Joyous Spring exceed the OCG Semi-Limited limit of two, so the result is theoretical and structural only. Structurally the deck is a connected Junk/Stardust Synchro system: Junk Synchron, Jet Synchron, Starjunk Synchron, Junk Meister and Mulcharmy give it a reasonable starter count and draw redundancy, while a full 15-card Extra Deck of Synchro bosses gives it strong end-board options. Interaction is dense (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster, Dark Ruler No More), which supports going-second play. Weaknesses are a brick-prone spread of 20 non-monster cards, zero side deck, and no recorded combos to confirm the median output. The score is not driven by Junk being a popular archetype, and it does not average individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 57, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal copy limit (-20); No side deck (-2). Final formula: Illegal cap: 0.80*Structural(57) + 0.20*TournamentReliability(45) = 54.6, capped to 30 as a theoretical/structural-only read (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.72 · 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 hand-trap and negation suite with Ash Blossom, Ghost Ogre, Droll & Lock Bird, Solemn Judgment and Majestic Star Dragon
• Full 15-card Extra Deck with strong Synchro boss coverage
• Redundant Junk and Synchron tuners give multiple paths to the same Synchro boss

Weaknesses

• Illegal list: Ash Blossom is over the OCG copy limit
• No side deck, so no post-side adaptability
• Many single-copy tech cards reduce consistency
• No recorded combos to confirm median output

Critical choke points

• Ash Blossom copy count must be cut to 2 before the list is playable
• The Junk Synchron / Meister starter density is the main opening-hand dependency

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring run 3 copies against an OCG Semi-Limited limit of 2; Main 55 / Extra 15 / Side 0 counts; Card text and stats for the listed cards; Usage stats: 8 of 9 core cards present
• Inferred: Starter probability of about 0.72 for the core set; Going-second hand-trap value; Brick risk from the non-monster count; Interaction quality from card text
• Provisional: Meta and matchup fit (D13) held neutral without a dated meta 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 record are absent no win-rate telemetry, so going-first and going-second splits are unknown Meta Power is provisional without a dated metagame sample side deck is empty, so post-side play cannot be assessed
