Identity & game plan

Win condition: Xyz Summon a Galaxy-Eyes or Number 62 / C62 style 4000-ATK boss from the Extra Deck, then attack through the board with Photon and Galaxy support; Galaxy-Eyes Afterglow and Photon Orbital ATK boosts plus Number 90 and Number 107 negations to close out a stalled board
Turn 1 (going first): Open a Galaxy Soldier or Photon Orbital starter, search a Photon or Galaxy card, and set up a Level 4 Xyz or Link line that threatens a Number 90 or Number 38 negate on the opponent's turn
Turn 2 (going second): Use the two hand traps (Red Reboot) and the Galaxy negates to break the opponent's first board, then rebuild with a Photon Emperor or Photon Vanisher recursion line
Recovery: Galaxy Summoner and Photon Jumper recover a Photon or Galaxy monster from the GY, and Photon Orbital's equip returns a searcher to hand
After siding: No side deck is registered, so there is no post-side plan; any sideboarding would have to be added before the deck can adapt

Why it scores here

The deck opens reliably: the core Photon and Galaxy starters are run at three copies, and the Galaxy and Photon searchers give the list a good chance of a live engine by turn two (Inferred). Its ceiling comes from Number 62 and Number C62 attacking through the board, plus the negate-and-boost Xyz bosses, which together let it convert a turn into a large swing. Its median output is lower, because no recorded boards exist to confirm how often that ceiling is reached, so the floor is scored from text and structure rather than observed results. Interaction is real but thin, with two hand traps, several negates and a small removal suite, and the deck has no side deck, which caps how well it can adapt. Popularity in the guides confirms the list is real and accessible, but no points were awarded for that, and card scores were not averaged into the deck score.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	66	P(at least one Galaxy Soldier or Photon Orbital in a 5-card opening hand) is about 0.34 per three-copy card; the archetype core group reaches about 0.82 (Inferred)
D2	Opening-Hand Quality & Brick Management	62	Fourteen searcher-text cards and eight singleton slots offer redundancy, but many Photon-only cards are dead without a Photon or Galaxy partner (Inferred)
D3	Combo Conversion & Ceiling	68	The guides describe a turn-two overkill through Number 62 and Number C62 with Afterglow boosts, but no recorded boards confirm it (Inferred)
D4	Combo Floor & Median Output	55	No recorded boards exist, so the median is estimated from the guides' description of a common turn-one negate and turn-two attack (Inferred)
D5	Interruption Resilience & Route Redundancy	62	Several negates (Number 90, Number 38, Number 107) and recursion through Galaxy Summoner and Photon Jumper give alternative lines after disruption (Inferred)
D6	Resource Economy, Recovery & Grind	62	Galaxy Soldier and Photon Orbital recover searchers, and the Galaxy Trance and Photon Emperor lines regenerate resources (Inferred)
D7	End-Board & Interaction Quality	66	Four negation cards, nine removal-text cards and two hand traps give layered interaction, though the hand traps are Semi-Limited Red Reboot copies (Verified text, Inferred quality)
D8	Going-Second & Board-Breaking Power	52	Going second, the two hand traps and Galaxy negates are the main tools against an established board, which is a moderate but not strong answer density (Inferred)
D9	Offensive Pressure & Closing Power	68	Number 62 and Number C62 at 4000 ATK, plus Afterglow boosts, give a strong closing threat (Verified stats, Inferred plan)
D10	Main Deck Efficiency & Flexibility	64	Forty main cards with a clean copy histogram and mostly Photon or Galaxy support keep the list coherent, although several off-archetype tech cards dilute the engine (Verified composition, Inferred)
D11	Extra Deck Efficiency & Coverage	60	The fifteen Extra Deck slots are dense with Xyz bosses, so the deck gets many threats, but it runs only one Fusion and one Synchro, leaving little flexibility (Verified composition)
D12	Side Deck Adaptability	30	The deck has no side deck at all, so there is no evidence of post-side adaptability and the score reflects that gap (Provisional)
D13	Matchup Coverage & Format Fit	50	No tournament share or dated meta sample is supplied, so format fit cannot be measured and is held near neutral (Provisional)
D14	Pilotability & Error Tolerance	40	The line needs several Xyz attachments, Photon-specific timing and negate-window decisions, which makes it moderately demanding to pilot (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 58, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: No side deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); Structural 59.8, TR 55, then -3 modifier, giving 56

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.82 · key two-card combo ≈ — · full-brick estimate ≈ 0.18 (all Inferred)
Combo output: best PowerIndex —, median —, board-per-starter —
Turn order: 0 going-first lines vs 0 going-second lines

Strengths

Three copies of the main starters give a high chance of a live opening hand (Inferred)
Strong closing threats at 4000 ATK with Afterglow boosts (Verified stats, Inferred plan)
Layered negates on the Extra Deck bosses give disruption resilience (Inferred)

Weaknesses

No side deck, so no post-side adaptation (Verified composition)
Thin hand-trap count against going-second boards (Inferred)
Off-archetype tech cards dilute the engine (Inferred)

Critical choke points

Red Reboot is the only hand-trap line, and its Semi-Limited status caps the copies run (Verified)
Number 62 and Number C62 need Xyz materials set up on the previous turn, so an early disruption can stall the closing line (Inferred)

Recommended changes

Priority	Remove	Add	Reason
1	none	a side deck of up to 15 cards	A side deck is the largest single gap; it gives the deck a post-side plan and the chance to answer the opponent's known strategy
2	the off-archetype tech cards with the weakest fit	Photon or Galaxy-compatible support or a second hand trap if legal	Replacing the weakest off-archetype slots would improve the engine's coherence and its going-second answers

Evidence & confidence

Verified: Main deck of 40 and Extra deck of 15 are legal for Master Duel; Copy limits are respected for Foolish Burial, Harpie's Feather Duster, Reinforcement of the Army and Red Reboot; The Xyz bosses and their printed ATK and DEF are as listed
Inferred: Opening-hand starter probability is about 0.82 for the core group; Turn-two overkill is consistent with the guides' description; Interaction density is moderate to good
Provisional: Meta Power and format fit are unknown without a dated metagame sample
Data gaps: No recorded boards exist, so the floor, median and ceiling are text-only inference No tournament link, so there is no meta share or per-pilot match record No win-rate telemetry exists for going-first, going-second, matchups or brick rates No side deck is registered, so post-side adaptability cannot be measured Meta Power is provisional unless a dated metagame sample is supplied
