Identity & game plan

Win condition: Ritual/Alien board pressure: Black Chaos, Magician of Dark Chaos - Black Chaos, Black Luster Soldier and Alien Overlord take over the board once a Ritual or Alien starter lands.; Dark Magician Destruction and Cosmic Slicer Zer'oll style Link/Fusion extension as a second threat, dependent on the legal Extra Deck slots.
Turn 1 (going first): Open on an Alien or Light and Darkness Ritual starter (Alien Ammonite, Mind Shuffle or Ragged Records of Rites) to search a second engine piece and set up a Ritual Summon.
Turn 2 (going second): Use Ash Blossom and Joyous Spring, Red Reboot or Maxx C to stop the opponent's first engine, then rebuild through the GY with Light and Darkness Ritual and Skull Archfiend of Chaos.
Recovery: Recover through the GY: Skull Archfiend of Chaos, Griffoh and Ragged Records of Rites return cards to the Deck and re-enable a Ritual or Alien line; Alien Stealthbuster and Alien Telepath handle interaction.
After siding: No Side Deck is registered (side_count 0), so no post-side plan can be scored; this is a structural gap.

Why it scores here

The deck is scored as a system, not by averaging its cards. Its reliable opening is limited: with 8 copies of the Alien/Ritual core, P(at least one core card in a 5-card opening hand) is about 0.69 (Inferred), so roughly a third of openings are non-functional. Its interaction suite (two Ash Blossom and Joyous Spring, Red Reboot, Maxx C, Crossout Designator, Planet Pollutant Virus) gives it real end-board and going-second strength. Conversion is capped by the split between Ritual, Alien, Theorealize and Power Patron sub-engines (exact archetype purity 20%), which reduces engine cohesion. Three Forbidden cards (Magicians' Souls, King of the Feral Imps x2, Red-Eyes Dark Dragoon) make the list illegal in the OCG format, so it receives a structural-only score and no popularity or meta credit was given.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	55	P(at least one core card in a 5-card hand) ~0.69 across 8 Alien/Ritual copies; engine split across sub-archetypes lowers consistency (Inferred)
D2	Opening-Hand Quality & Brick Management	45	Archetype core covers ~31% of going-first hands; 16 sub-archetype names and off-archetype singletons raise brick risk (Inferred)
D3	Combo Conversion & Ceiling	50	No recorded boards; ceiling inferred from Black Chaos, Magician of Dark Chaos and Black Luster Soldier ritual routes (Inferred)
D4	Combo Floor & Median Output	35	No recorded boards, so the median is not measurable; the deck depends on a specific ritual starter (Inferred)
D5	Interruption Resilience & Route Redundancy	50	Alien and Ritual lines have several searchers and recursion routes (13 searcher-text cards), but one choke point per line remains (Inferred)
D6	Resource Economy, Recovery & Grind	45	GY recursion via Skull Archfiend of Chaos, Griffoh and Ragged Records of Rites; no resource signature data (Inferred)
D7	End-Board & Interaction Quality	60	Two Ash Blossom, Red Reboot, Maxx C, Crossout Designator and Planet Pollutant Virus give layered interaction (Verified card text, Inferred quality)
D8	Going-Second & Board-Breaking Power	55	Going-second hand-trap coverage: P(at least one of 4 hand traps in 6 cards) ~0.49 (Inferred); Planet Pollutant Virus adds board breaking (Verified text)
D9	Offensive Pressure & Closing Power	55	Black Chaos 3000 ATK, Black Luster Soldier 3000 ATK and Magician of Dark Chaos 2800 ATK give closing power once a Ritual lands (Verified stat, Inferred conversion)
D10	Main Deck Efficiency & Flexibility	40	40-card Main with 24 singletons and 40 off-exact-archetype copies; compactness is weak (Verified composition)
D11	Extra Deck Efficiency & Coverage	35	Extra Deck has 10 cards, but 3 of them are Forbidden (King of the Feral Imps x2, Red-Eyes Dark Dragoon), leaving 7 legal slots (Verified legality)
D12	Side Deck Adaptability	10	No Side Deck (side_count 0); no post-side plan is possible (Verified legality)
D13	Matchup Coverage & Format Fit	35	No tournament link and no dated meta sample; Forbidden cards also reduce format fit (Provisional)
D14	Pilotability & Error Tolerance	45	Multi-step Ritual, Link and Fusion lines with many decision points; moderate-to-high pilot demand (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 46, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-10); engine conflicts (-2). Final formula: Illegal: theoretical/structural-only cap. 0.80*Structural(46.3) + 0.20*TournamentReliability(40) + ContextModifiers(-12) = 33; Meta provisional

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (all Inferred)
Combo output: best PowerIndex —, median —, board-per-starter —
Turn order: 0 going-first lines vs 0 going-second lines

Strengths

Layered interaction suite: two Ash Blossom and Joyous Spring, Red Reboot, Maxx C, Crossout Designator and Planet Pollutant Virus
High-ceiling ritual boards (Black Chaos, Black Luster Soldier, Magician of Dark Chaos) once a starter lands
13 searcher-text cards supply redundancy across the Deck

Weaknesses

Three Forbidden cards make the list illegal in OCG
No Side Deck, so no post-side adaptability
Low archetype purity (20%) and several competing sub-engines reduce engine cohesion

Critical choke points

A single Ritual or Alien starter in the opening hand, with about a 31% chance of none in 5 cards
Ritual Summon requires specific Light and Darkness Ritual pieces that are not guaranteed by search

Recommended changes

Priority	Remove	Add	Reason
1	Magicians' Souls, King of the Feral Imps (x2), Red-Eyes Dark Dragoon	Legal replacements that fit the Alien/Ritual engine, within the OCG copy limits	The list is illegal; the Forbidden cards must leave before any normal score applies.
2	Off-archetype singletons with weak engine links	A legal Side Deck (0 cards now) covering the matchups the Ash and Red Reboot interaction does not reach	Side coverage is absent, and a Side Deck gives the deck a post-side plan.
3	Duplicate sub-engine pieces (Theorealize, Power Patron)	More copies of the core Alien or Light and Darkness Ritual pieces	Consolidating on one engine raises starter consistency and reduces brick risk.

Evidence & confidence

Verified: Legality: 3 Forbidden cards run; deck is Illegal; Main 40 and Extra 10 meet GameplayType size rules; Side 0; Card text and stats for every listed card; Hypergeometric starter probabilities
Inferred: Consistency estimates (D1, D2) from hypergeometric odds; Interaction quality (D7) from card text; Going-second strength (D8) from hand-trap odds; Pilot demand (D14) from combo step count
Provisional: Meta Power (no dated metagame sample); Format fit (D13) with no 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 Side Deck, so post-side performance cannot be scored no win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied
