Junk Deck #771801 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 33/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• 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 Dragon or Junk Warrior and convert the board with 2500 to 4000 ATK monsters (Shooting Quasar, Cosmic Blazar, Red Supernova) plus Junk Warrior pressure; Stardust Dragon and Stardust Trail follow-up after the Junk Synchron or Junk Meister opening
• Turn 1 (going first): Open a Junk Meister or Synchron starter, search a Junk or Synchron Tuner, and Synchro Summon into a Dragon or Junk Warrior on turn 1 or 2; keep Ash Blossom and Ghost Ogre up as interaction
• Turn 2 (going second): Use the 6-card hand's hand traps (Ash Blossom, Ghost Ogre, Effect Veiler, Droll and Lock Bird, Infinite Impermanence) to stop the opponent's first summon or search, then rebuild through Junk Synchron recursion
• Recovery: Recycle Synchron and Junk monsters from the GY through Jet Synchron, Anchorbolt Hedgehog and Junk Synchron's GY effect; re-Synchro through Synchro Overtop or Synchro Overtake if the board is cleared
• After siding: Not evaluable: the deck runs no side deck (side_count 0), so there is no post-side plan

Why it scores here

The deck is illegal as submitted: Ash Blossom & Joyous Spring is run three times against a Semi-Limited limit of two, so the normal Final Contextual score is capped and the figure above is a structural-only read. Its engine is a Junk and Synchron core, but most engine pieces are single copies (Junk Synchron, Junk Warrior, Jet Synchron, Starjunk Synchron), while Junk Meister is the only triple-copy starter, so opening-hand consistency is low (Inferred). The 15-card Extra Deck carries real closing power (4000-ATK Synchro Dragons), and ten hand traps give it solid interaction on the going-second side. Popularity and the archetype's usage data were not credited, and card scores were not averaged into the deck score. No combos were supplied, so floor, median and ceiling are text-only inferences and the confidence is Low.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 45, Going First ≈ 40, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (illegal copy count) (-8); no side deck (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then illegal-deck cap applied: 43 - 10 modifiers = 33 (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

• Ten hand traps and 17 negation-text cards give layered interaction on the going-second side
• Strong Synchro boss options in the Extra Deck, including several 4000-ATK monsters
• Multiple searchers and Synchron GY recursion keep card flow going

Weaknesses

• Most engine pieces are single copies, so the opening hand often misses the engine
• Ash Blossom & Joyous Spring is over the copy limit, which makes the list illegal as submitted
• No side deck, so the deck cannot adapt between games of a best-of-3
• Low archetype purity (15.1% exact-name) with many generic tech and off-archetype slots

Critical choke points

• Junk Synchron and Junk Warrior are 1-of; losing them removes the main Junk Synchro line
• The Junk Meister starter depends on revealing a Warrior or Stardust Synchro in the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Ash Blossom & Joyous Spring is run 3 copies against a Semi-Limited limit of 2, making the list illegal; Main 58, Extra 15, Side 0 are within OCG size rules; Extra Deck is 15 Synchro monsters; 4000-ATK Synchro bosses are present; Ten hand traps and 17 searcher-text cards are present in the main deck
• Inferred: Opening-hand consistency is low because most engine pieces are single copies; Going-second interaction is layered by the hand-trap count and the 0.70 probability of at least one in 6 cards; Recovery depends on Synchron GY recursion and Jet Synchron
• Provisional: Meta power is null: no dated metagame sample was supplied; Format fit is a provisional mid value because no tournament context exists
• 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; going-first and going-second splits are Inferred no side deck; post-side plan cannot be assessed Meta Power is provisional without a dated metagame sample
