Codebreaker Deck #785178 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun, 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: Special Summon Sacred Beast Level 10 monsters (Raviel, Uria, Hamon) and Phantasm Extra Deck finishers such as The Chaotic Phantasmal Sacred Beasts and Superdreadnought Rail Cannon Gustav Rocket for a 5000 ATK closing board; Link and Codebreaker Extra Deck boards that chain Special Summons through link arrows
• Turn 1 (going first): Open a Sacred Beast starter or searcher (Card of the Soul, Sacred Beasts Thunderclap, Martyr of the Sacred Beasts), convert into a Level 10 Sacred Beast, and keep a hand trap (Ash Blossom, Effect Veiler, Ghost Ogre) up for the opponent's first response
• Turn 2 (going second): Use a hand trap on the opponent's first search or summon, then rebuild through Sacred Beasts Released and Martyr recursion
• Recovery: Recycle Sacred Beasts Released and Martyr of the Sacred Beasts from the Graveyard and banishment, and re-summon Level 10 Sacred Beasts
• After siding: Side in Ghost Belle & Haunted Mansion, PSY-Framegear Delta and Codebreaker Zero Day for extra hand-trap or board-clearing depth, with the Ash Blossom copy count corrected first

Why it scores here

The score comes from how the deck works as a system, not from averaging its card scores. Its Sacred Beast core (three copies of the Level 10 summoners and Sacred Beasts Released / Thunderclap as searchers) gives a moderate chance of a live starter in the opening hand, and recursion from the Graveyard helps it rebuild after a disruption. Ten hand traps give it a strong answer to the opponent's first action going second, and its Phantasm and Link finishers have a high closing ceiling when the engine goes off. Two things hold the score down: the list breaks the Ash Blossom copy limit, so it is Illegal and capped at a low theoretical score, and no recorded boards, tournament results or guides exist to confirm the ceiling or the median. Popularity of the archetype earned no points, and the Extra Deck spread across several sub-archetypes weakens engine coherence.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 55, Going First ≈ 50, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); unverified ceiling (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*55 + 0.20*45 - 12 = 41, then capped to 35 because the deck is Illegal (theoretical/structural only, Step 2)

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

• Ten hand traps and multiple negation effects answer the opponent's first action going second
• Sacred Beast searchers and recursion give several routes back into the engine
• Phantasm and Link Extra Deck finishers have a high closing ceiling

Weaknesses

• Illegal as built: Ash Blossom & Joyous Spring is run at 3 copies against a limit of 2
• Extra Deck spread across several sub-archetypes weakens engine coherence
• No recorded boards, guides or tournament data to confirm the median or ceiling

Critical choke points

• The Level 10 Sacred Beast summon route depends on a single starter and a searcher being in hand together
• Ash Blossom copy count must be corrected before the list is playable

Recommended changes

Evidence & confidence

• Verified: Main 40, Extra 15, Side 15 are within the OCG size rules; Ash Blossom & Joyous Spring is run at 3 copies against a Semi-Limited limit of 2; Card text for the Sacred Beast, Phantasm and Link finishers
• Inferred: Starter access in opening hands; Hand-trap coverage of going-second openings; Interaction breadth from card text
• Provisional: Matchup and format fit; Post-side plan quality
• Data gaps: No recorded boards, so the combo floor, median and ceiling are text-only inference No tournament link, so archetype share and per-pilot results are absent No win-rate telemetry exists, so going-first and going-second performance is Inferred Meta Power is Provisional because no dated metagame sample was supplied
