Deck — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (±10 · Confidence: Medium)
| Overall score | Value |
|---|---|
| Structural Deck Power | 47 |
| Going First | 45 |
| Going Second | 45 |
| Meta Power | provisional |
| Tournament Reliability | 40 |
- Primary strategy: Midrange
- Secondary strategies: Combo, Toolbox
- Format: ocg
Legality
Main 40 / Extra 14 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Ritual Summon Mitsurugi Ritual monsters (Ame no Murakumo no Mitsurugi, Futsu no Mitama no Mitsurugi) for board pressure, backed by Reptile recursion and Xyz/Link extenders; Ryzeal Duo Drive and Ryzeal Detonator Xyz pressure, plus Ragnaraika Chain Coils and Zombie Vampire as extra-deck threats
- Turn 1 (going first): Search a Mitsurugi monster or Ritual Spell with Mitsurugi no Mikoto (Saji/Aramasa/Kusanagi), then Ritual Summon a Mitsurugi Ritual monster; Ogdoadic Water Lily and Nauya as secondary starters
- Turn 2 (going second): Use Mitsurugi Great Purification and Mitsurugi Magatama as interaction, then Ritual or recurse a Reptile threat from the GY
- Recovery: Snake Rain and Ragged Records of Rites refill Reptiles and Ritual Spells; Nephilabyss and Derk recur from the GY
- After siding: Not evaluable: the deck runs no side deck (0 cards)
Why it scores here
The deck is Illegal in OCG: it runs 3 copies of Ame no Habakiri no Mitsurugi and 1 King of the Feral Imps, both Forbidden with 0 legal copies, so the score is capped and the evaluation is structural-only. Structurally, the Mitsurugi core is reliable at the opening-hand level: the searchers (20 text-tagged cards) give about 0.98 odds of at least one searcher in a 5-card hand (Inferred), and the Mitsurugi/Reptile line can convert into a 3200-ATK Ritual monster and a board-clearing effect. The deck does not reach a strong score for three reasons: it has no recorded boards, so ceiling and median output are text-only estimates; it runs no hand traps and few answers, so interaction and resilience are thin; and it splits across Mitsurugi, Ryzeal, Ogdoadic, Cyberse, and Apophis with only 0% exact-archetype purity, so the engines conflict. Popularity was not credited: usage data shows only 64% of the core cards are present, and the deck has no sideboard and no tournament record. Scores were built from the system as a whole, not averaged from card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(at least 1 of 23 Mitsurugi-core cards in 5-card opening hand) ~0.99 as a proxy; individual 2-copy starters ~0.24 each (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | Ritual and tribute requirements plus 6 Ritual monsters and 2 Ritual Spells create some dead-hand risk; no hand traps or generic draw to cover bricks (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No recorded boards (combos_evidence total 0); ceiling estimated from card text only (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded boards, so median output is unknown; estimate reflects text-only reading (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 45 | Recursion through Nephilabyss, Derk, and Mitsurugi Great Purification exists, but there are few independent lines and no hand traps (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Searcher and recursion text is dense (20 searcher-tagged cards); Snake Rain and Ragged Records refill the GY (Inferred) |
| D7 | End-Board & Interaction Quality | 45 | 6 negation-text cards and 8 removal-text cards, but no hand traps and no floodgates (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 50 | Ame no Murakumo's board wipe is a going-second answer, but it is limited by the Ritual requirement (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Top ATK: Ame no Murakumo 3200, Zombie Vampire 3000, Ryzeal Detonator 3000, Ragnaraika 2900 (Verified stats, Inferred plan) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 40 main cards, 31 distinct, with 24 one-of cards and 3-copy lines of Forbidden cards removed; purity is 0% exact-archetype (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 40 | 14 Extra cards mix Xyz, Link, Synchro, and Fusion, and several (Crimson Dragon, Dyna Mondo, Masquerena) have no clear role in this list (Inferred) |
| D12 | Side Deck Adaptability | 15 | No side deck (side_count 0); post-side adaptability cannot be scored (Verified gap) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link or dated meta sample; archetype share unavailable (Provisional) |
| D14 | Pilotability & Error Tolerance | 35 | Multi-step Ritual, tribute, and recursion sequencing with several decision points per turn (Inferred) |
How the score was computed
Strategy profile: Midrange primary, Combo secondary; structural score uses the Midrange profile. Structural ≈ 47, Going First ≈ 45, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-8); Engine conflict (-4). Final formula: Illegal deck: normal formula (0.80*Structural + 0.20*TournamentReliability, Meta provisional = 46 before modifiers) gives 34 after banlist and conflict modifiers; capped to 25 because the list is illegal (Forbidden cards and an incorrect copy count). Structural-only.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.99 · 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
- Strong searcher density (20 searcher-tagged cards) gives high odds of finding a starter
- Ritual Monster and Mitsurugi Ritual lines convert hand resources into high-ATK boards
- Popular Mitsurugi core (Mitsurugi Mirror, Kusanagi, Futsu no Mitama, Wousu, Great Purification) is present
Weaknesses
- Illegal in OCG: Forbidden cards and copy-limit violations
- No hand traps or floodgates; interaction is text-only
- No sideboard, so no post-side plan
- Engine conflicts across Mitsurugi, Ryzeal, Ogdoadic, and Cyberse sub-archetypes
Critical choke points
- Ritual Summon requires the Mitsurugi Ritual or Mitsurugi Mirror, plus a Level-matched tribute set; losing these cards stops the main line
- Reliance on Reptile-type monsters for tributes, recursion, and most payoffs
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 3x Ame no Habakiri no Mitsurugi | Legal Mitsurugi or Reptile Ritual monsters or searchers, up to the copy limit | Forbidden in OCG with 0 legal copies; the deck is illegal until these are removed, and the main deck drops to 37 cards, below the 40-card minimum, so 3 legal replacements are required |
| 2 | 1x King of the Feral Imps | Legal Extra Deck option matching the deck's Xyz or Link lines | Forbidden in OCG; removing it keeps the Extra Deck at 13 legal cards |
| 3 | Off-plan Extra Deck cards with no clear role (for example Crimson Dragon or Dyna Mondo) | Cards that continue the Mitsurugi or Ryzeal line | Engine conflicts reduce consistency; usage data shows the core cards missing (Reptilianne Echidna, I:P Masquerena, S:P Little Knight) |
Evidence & confidence
- Verified: Deck is Illegal: 3x Ame no Habakiri no Mitsurugi and 1x King of the Feral Imps are Forbidden with 0 legal copies; Main 40, Extra 14, Side 0; all sizes within OCG limits; Exact-archetype purity 0%; sub-archetype spread recorded
- Inferred: Opening-hand starter odds (~0.99 proxy; 0.24 per 2-copy starter); Interaction and resilience estimates from text roles; Going-first and going-second estimates
- Provisional: Meta Power (null); Matchup fit (no dated metagame sample)
- Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry for this deck Meta Power is Provisional unless a dated metagame sample is supplied No side deck, so post-side adaptability is unscored
