Galaxy Photon Deck #770703 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Galaxy-Eyes Photon Dragon and Galaxy-Eyes Tachyon Primal pressure through Xyz and Dragon attacks, backed by Number C107 and Number 62 (Inferred from text, no recorded boards); Hand-trap-supported negation of the opponent's key monsters and spells, then a large Xyz board (Inferred)
• Turn 1 (going first): Open with 5 cards, hope for a starter such as Galaxy-Eyes Tachyon Primal, Mulcharmy Fuwalos or Galaxy-Eyes Photon Dragon, then extend into a Dragon Xyz (Inferred; P of at least one core card in opening 5 is about 0.65)
• Turn 2 (going second): Hold hand traps (Ash Blossom, Infinite Impermanence, Effect Veiler, Ghost Ogre and Snow Rabbit, Nibiru) to answer the opponent's first summon and then build a board from the remaining hand (Inferred)
• Recovery: Galaxy Stealth Dragon, Trade-In and Mulcharmy Fuwalos draw and refill; Tachyon Cloudragon and Tachyon Spiral of Destruction recycle from the GY (Inferred from text)
• After siding: Not evaluable: the deck has no side deck (0 cards), so no post-side plan exists

Why it scores here

The deck's reliable opening is limited: only 4 of 15 usage-core Galaxy-Eyes/Photon cards are present, and the archetype core group gives about 0.65 chance of at least one core card in a 5-card opening hand, so the deck often starts from generic tech. Its strongest attribute is interaction: 13 hand traps and 22 negation-text cards give it layered answers to the opponent's first summon, which supports the going-second hand (P of at least one hand trap in 6 cards is about 0.82) and earns the endboard and going-second dimensions. Conversion and median output could not be measured because no combo boards are recorded, so those scores are text-only inferences and stay low. The deck has no side deck, and the copy-limit violations make it Illegal, so its final score is capped and reported as a structural estimate only. Popularity of the Galaxy archetype did not earn points, and the score was computed from the system's dimensions rather than from an average of card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 48, Going First ≈ 42, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal copy-limit violations (-9); Banlist exposure (-2). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability = 46.4, then context modifiers -11 for the Illegal copy-limit violations and banlist exposure, giving 35 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.65 · 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 interaction: 13 hand traps and 22 negation-text cards give several answers per game
• Strong going-second hand-trap coverage (about 0.82 for at least one in 6 cards)
• Large Xyz top end, including Number C107 at 4500 ATK and Neo Galaxy-Eyes Prime at 4000 ATK
• Some recursion and draw: Trade-In, Mulcharmy Fuwalos, Tachyon Cloudragon

Weaknesses

• Illegal as built: two copy-limit violations
• Only 4 of 15 usage-core Galaxy-Eyes/Photon cards present; many generic tech cards dilute the engine
• No side deck, so no post-side adaptation
• No combo data, so conversion and median output are unmeasured

Critical choke points

• Galaxy-Eyes Photon Dragon and Galaxy-Eyes Tachyon Primal, the main starters (3 and 2 copies respectively, one Extra-based route each)
• Single Xyz chain: most lines depend on one Dragon Xyz being live
• Limited cards (Foolish Burial, Monster Reborn, Harpie's Feather Duster) each run once, so losing one removes a line

Recommended changes

Evidence & confidence

• Verified: Illegal status: Ash Blossom 3 copies vs 2 legal, Seventh Tachyon 2 vs 1 legal; Main 55 / Extra 15 / Side 0 within OCG size rules; Banlist statuses for the 7 restricted cards
• Inferred: Hypergeometric opening-hand odds for starters and hand traps; Strategy classification as Midrange with Toolbox secondary; Dimension scores D1 to D11 and D14 from card text and composition
• Provisional: Meta Power and D13 matchup fit: no dated metagame sample or tournament link
• 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 absent No win-rate telemetry: going-first and going-second results are unknown Side deck is empty, so post-side plans cannot be assessed Deck title is null in the export
