Identity & game plan

Win condition: Ritual boss monsters (Ruler of the End of the World, Ame no Murakumo no Mitsurugi, Nekroz of Brionac/Unicore) recovered through Mitsurugi and Nekroz ritual spells; Extra Deck Xyz and Link beats (Dragluxion, Number 38, Ragnazero, S:P Little Knight)
Turn 1 (going first): Open a ritual starter, search the Ritual Spell (Mitsurugi Ritual or Nekroz Kaleidoscope) and a monster, then ritual summon a boss; the plan depends on one of roughly 9 ritual-spell and starter cards in the opening hand (Inferred)
Turn 2 (going second): Use the 8 hand traps and Ash Blossom to slow the opponent's first summon, then convert with Mulcharmy draws and the ritual boss (Inferred)
Recovery: Mulcharmy draw effects and Pot of Sloth refill cards, and searchers (Emilia, Avance, Mitsurugi no Mikoto) rebuild the ritual line from the Deck (Inferred)
After siding: Not evaluable: the deck has no Side Deck (side_count 0)

Why it scores here

The score comes from the deck as a system, not from averaging its cards. Its strongest part is interaction: 8 hand traps, Ash Blossom, Droll and Solemn Judgment give a dense layer of negation that holds up against going-second openings, which is what lifts D7 and D8. Its ritual engine is inconsistent. Ritual Spells are split across three names, and the Nekroz and Mitsurugi starters have low copy counts, so D1 and D2 stay moderate and the ceiling (D3) is only text-inferred. The deck has no combo records, no tournament link and no Side Deck, so D4, D12 and D13 are provisional. Popularity did not earn points, and the deck is illegal: 5 Forbidden cards are over the copy limit, including 3 copies of Ame no Habakiri no Mitsurugi, so the Final score is capped with a banlist-exposure modifier and is theoretical only.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	55	Ritual starter density is moderate: P(>=1 Nekroz Ritual Spell or starter in 5 cards) is roughly 0.4 to 0.6 from the copy table; Mitsurugi Ritual x3 and Nekroz Kaleidoscope x1 are the only Ritual Spell access (Inferred)
D2	Opening-Hand Quality & Brick Management	45	34 distinct Main Deck cards with 17 singletons and split Ritual Spell names, so hands often hold a Ritual Monster with no matching spell or a spell with no monster (Inferred)
D3	Combo Conversion & Ceiling	55	No parseable boards in combos_evidence; ceiling is a text read of Mitsurugi Ritual into Ame no Murakumo, which can destroy all opposing monsters (Inferred)
D4	Combo Floor & Median Output	45	No recorded combo median, so the floor is a text-only read that depends on the ritual line converting (Inferred)
D5	Interruption Resilience & Route Redundancy	45	Recovery depends on Mulcharmy draws, Pot of Sloth and searchers, but there is no independent second line if the ritual starter is stopped (Inferred)
D6	Resource Economy, Recovery & Grind	55	Mulcharmy Fuwalos and Purulia draw, Pot of Sloth and Pot of Prosperity recover cards, and Emilia and Avance search, so resources are rebuilt but at a cost in Extra Deck and Life Points (Inferred)
D7	End-Board & Interaction Quality	72	Interaction is dense: 8 hand traps, 15 negation-text cards, and Ash Blossom x2, Droll and Lock Bird, Solemn Judgment and Dimensional Barrier, with Red Reboot for Trap activations (Verified text, Inferred quality)
D8	Going-Second & Board-Breaking Power	60	Going-second hand-trap coverage is P(>=1 of 8 hand traps in 6 cards) = 0.59 (Inferred); the boards it answers are not measured (Inferred)
D9	Offensive Pressure & Closing Power	60	The closing boss is Ame no Murakumo no Mitsurugi at 3200 ATK and Ruler at 3000 ATK, with Dragluxion and Number 38 as Extra Deck closers (Verified stats, Inferred)
D10	Main Deck Efficiency & Flexibility	45	All 60 Main Deck slots are used with 34 distinct cards and many 3-copy staples, so the list is full and has little flex room (Inferred)
D11	Extra Deck Efficiency & Coverage	50	The 15-card Extra Deck mixes Xyz, Link, Synchro and Fusion with a single Fusion and only Dragluxion and Number 38 as reliable closers, so mandatory slots are unclear (Inferred)
D12	Side Deck Adaptability	10	No Side Deck (side_count 0), so there is no post-side plan to score (Verified)
D13	Matchup Coverage & Format Fit	40	No tournament_context and no dated meta sample; the archetype share is unknown, so this is Provisional
D14	Pilotability & Error Tolerance	35	Ritual Summons need exact Tribute and Level math, and several effects are once per turn with overlapping names, so error tolerance is low (Inferred)

How the score was computed

Strategy profile: Midrange primary; Toolbox secondary, not separately weighted. Structural ≈ 51, Going First ≈ 50, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional), then the illegal-deck banlist modifier; theoretical structural read only

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.23 · 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 negation layer: 8 hand traps plus Ash Blossom x2, Droll, Solemn Judgment and Dimensional Barrier
Several searchers and draw effects that smooth consistency
Multiple boss monsters with high ATK (Ruler, Murakumo, Dragluxion)

Weaknesses

Illegal list: 5 Forbidden cards, 3 of them over the limit
Ritual Spells split across three names, so starter access is uneven
No Side Deck and no post-side plan
No combo records or tournament data, so most scores are Inferred

Critical choke points

Ritual Summon of the end boss depends on one of the 9 ritual-spell and starter cards in the opening hand
Removing the Forbidden Mitsurugi cards leaves a much thinner ritual engine

Recommended changes

Priority	Remove	Add	Reason
1	Ame no Habakiri no Mitsurugi (copies beyond the legal limit of 0, 3 copies run)	Legal Ritual monster or Mitsurugi-independent boss	The deck is illegal; the list must be made legal before any Final score applies
2	Forbidden Extra Deck cards: Bahamut Shark, King of the Feral Imps, Number 60, Albion	Legal Extra Deck Xyz, Link or Fusion closers	Forbidden cards cannot be run at all in OCG, so the Extra Deck closers have to change
3	One ritual-spell name from the three-name split	A single consistent Ritual Spell line	Splitting starter access across names drives the brick rate in D2

Evidence & confidence

Verified: Legality: 5 Forbidden cards in the list, 3 copies of Ame no Habakiri over the limit, Main 60 and Extra 15 are within size rules; Banlist statuses for Limited and Semi-Limited cards; Card text and stats for the listed cards
Inferred: Ritual starter access and brick rate from hypergeometric estimates; Interaction density read from card text; Going-second hand-trap coverage (0.59); Closing power from ATK values and text
Provisional: Meta Power is null; no dated metagame sample; Matchup fit (D13) with no tournament data
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: post-side adaptability cannot be measured no win-rate telemetry: going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
