Junk Deck #755274 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±8 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, 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: Synchro summon a large Junk/Stardust/Scrap Synchro boss (Red Supernova Dragon, Cosmic Blazar Dragon, Bystial Dis Pater) off a Junk Synchron or Stardust Synchron starter chain; Stardust Dragon and Accel Synchro Stardust Dragon board presence, with hand-trap protection of the engine
• Turn 1 (going first): Open a Junk Synchron or Stardust Synchron, search via Junk Meister, Junk Armor or Synchro Fellowship, then Synchro Summon a boss. Keep Ash Blossom and Ghost Belle up for the opponent's first response.
• Turn 2 (going second): Hold Ash Blossom, Ghost Belle, Ghost Ogre, Droll and Nibiru to interrupt the opponent's setup, then convert with a Synchro boss after the board is cleared.
• Recovery: Recurse Synchrons from the GY via Jet Synchron and Starjunk Synchron, and rebuild with Junk Meister and Full-Speed Warrior searches.
• After siding: Not evaluable: the deck runs no side deck (side_count 0).

Why it scores here

The Junk engine reliably opens a Synchro starter: 23 core-archetype copies give about a 94% chance of at least one in a 5-card opening hand (Inferred, hypergeometric). The recorded combo data is empty, so the ceiling and median come only from card text, and both are rated Inferred. The deck has real interaction density with 15 hand traps and 19 negation-text cards, which is why the going-second score is higher than the going-first score. Structural power was computed on the deck as a system. Archetype popularity earned no points, and no card scores were averaged. Illegal status caps the final score: three cards are Forbidden and two are over their copy limit, so this is a theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 45, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-6); copy-limit violations (-6). Final formula: Illegal cap applied (theoretical/structural-only): raw 0.80*56 + 0.20*40 = 52.8, with -12 modifiers = 40.8, capped to 35. Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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

• Core Junk and Synchron starters have high redundancy in the opening hand
• Dense hand-trap and negation text gives layered interaction on both turns
• Boss ceiling reaches 3500 to 4000 ATK with several Synchro options

Weaknesses

• Illegal list: three Forbidden cards and two copy-limit violations
• No side deck, so there is no post-side adaptation
• Tech density (23 tech cards) and many singletons lower compactness and raise brick risk
• No recorded boards, so combo conversion is unverified

Critical choke points

• Junk Synchron or Stardust Synchron must be live to start most lines
• Hand traps are the main defence and cannot be replaced once the deck is legalised without losing density

Recommended changes

Evidence & confidence

• Verified: Main deck is 55 cards, extra deck 15, side deck 0; Called by the Grave, Crystal Wing Synchro Dragon and Triple Tactics Talent are Forbidden in OCG; Ash Blossom & Joyous Spring runs 3 copies against a 2-copy limit; Droll & Lock Bird runs 2 against 1; Core starter hypergeometric odds: 0.94 for at least one in a 5-card hand
• Inferred: Going-second hand-trap coverage about 0.87; Ceiling and median derived from card text only; Interaction density from negation and removal text
• Provisional: Meta Power and format fit, pending a dated metagame sample
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and pilot match record absent no win-rate telemetry; going-first and going-second splits are inferred no side deck; post-side plan cannot be scored Meta Power provisional until a dated metagame sample is supplied
