Codebreaker Deck #788797 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 15 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Level 10 Sacred Beast bosses (Raviel 4000 ATK, Hamon 4000 ATK, Chaotic Phantasmal 5000 ATK) summoned through the Phantasm engine, with Codebreaker and Cyberse Link monsters as secondary pressure; Link beats from Codebreaker Virus Berserker (2800 ATK) and Codebreaker Virus Swordsman (2300 ATK) if their Codebreaker enablers are present
• Turn 1 (going first): Open with Martyr of the Sacred Beasts or Calamity-line searches (Sacred Beasts Thunderclap, Sacred Beasts Released, Card of the Soul) to fetch a Sacred Beast Continuous Spell or Field Spell and set up a Level 10 summon
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Effect Veiler, Nibiru) to stop the opponent's first summon chain, then convert the surviving Sacred Beast into a Level 10 boss
• Recovery: Recur Martyr of the Sacred Beasts and Fallen Paradise of the Sacred Beasts from the Graveyard and banishment, and use Sacred Beasts Released to refill the hand from the Deck
• After siding: Bring in Infinite Impermanence, Skull Meister and Artifact Lancea against hand-trap-light or board-heavy opponents, and Mistaken Arrest to slow the opponent's searches; the side list is coherent but has no recorded performance data

Why it scores here

The deck is an illegal list because three copies of Ash Blossom & Joyous Spring exceed the OCG limit of two, so it receives no normal Final score and is capped at 30 as a structural-only read. Its structural core is a Phantasm Sacred Beasts shell that reliably finds its searchers (Martyr, Thunderclap, Released, Card of the Soul), then converts into Level 10 bosses at 4000 to 5000 ATK, backed by 13 hand traps and 7 negation-text cards that give layered interaction. The Extra Deck has 12 Link monsters and 2 Thunder Dragon Colossus that the main deck supports weakly: Colossus has no Thunder Dragon support in the Main Deck, and several Link monsters need Cyberse or Codebreaker material the deck barely runs, which costs both efficiency and consistency. No recorded boards, tournament results, or dated meta exist, so ceiling and median are text-based estimates and Meta Power is null. Archetype popularity earned no points, and the score comes from the deck's system behavior rather than from averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange primary, Control weighting blended in only as a disclosure; Midrange profile used for Structural. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Engine conflicts (-3); Banlist exposure (-1); Illegal list cap (0). Final formula: Uncapped: 0.80*Structural(49) + 0.20*TournamentReliability(40) + modifiers(-4) = 43; Illegal cap applied, reported as 30 (structural-only, no normal Final score). Meta Power provisional/null.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 searcher text (20 cards) keeps the Phantasm engine accessible
• Going-second hand-trap coverage is high (92% for at least one hand trap in six cards)
• Level 10 bosses at 4000 to 5000 ATK give closing power
• Side deck offers coherent post-side options against hand-trap-heavy or board-heavy opponents

Weaknesses

• Illegal copy count: three Ash Blossom & Joyous Spring against a limit of two
• Extra Deck is Link-heavy with support the Main Deck barely provides
• Two Thunder Dragon Colossus have no Thunder Dragon support in the Main Deck
• High hand-trap and tech density (13 each) increases dead-hand risk

Critical choke points

• Martyr of the Sacred Beasts and the Sacred Beast search cards are the only route to Level 10 bosses
• The single Codebreaker Zero Day in the Main Deck is the only Codebreaker starter for the Codebreaker Link monsters

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 15 are within OCG size rules; Ash Blossom & Joyous Spring: 3 copies run, OCG Semi-Limited with 2 legal copies; Droll & Lock Bird, Linkuriboh and S:P Little Knight are Limited with 1 copy each (legal); Card text for the Phantasm, Codebreaker and hand-trap cards as supplied in the excerpts; Archetype usage data shows the Phantasm core cards are included at 100% in the Main Deck
• Inferred: Engine accessibility from hypergeometric starter odds; Going-second hand-trap coverage (92%); Interaction density and layering from card text; Extra Deck coherence and Link material availability; Pilotability and decision load from the summon chains
• Provisional: Meta Power (null) and format fit (D13); Tournament Reliability (no dated meta or match record); Post-side performance (D12)
• Data gaps: No recorded boards: combo floor, median and ceiling are text-only inferences No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry for going-first/second, matchup, game-level, brick, starter or OTK rates Meta Power is provisional unless a dated metagame sample is supplied Usage data flags Extra Deck Link and Fusion cards as not in the deck even though they appear in the Extra Deck list; the 'missing core' count (56%) therefore understates what the list runs and is not used for scoring No deck title supplied
