Why it scores here
Mitsurugi Mirror is a Ritual Spell that Ritual Summons a Reptile Ritual Monster from hand or GY, paid by Reptile tributes from hand or field. Its score rests on being the enabling piece of the Mitsurugi line: it is in all 400 sampled decks and all 40 recorded combos, and those boards average a structural power index of 82.2. The card's own stats earn nothing: it is a spell with no ATK/DEF, no opponent interaction, and no material value, and the GY shuffle-to-Deck clause is a minor recovery. The combo evidence does not tag any role on the card (all role counts are 0), so the combo-conversion score is inferred from board context, not from a demonstrated role. The 100% deck and partner rates are largely a selection effect and are not used as a power signal.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Sits in 400 of 400 sampled decks with 1.08 average copies and a Mitsurugi archetype inclusion of 88 to 94 percent, but no searcher or starter route is recorded in combo data (starter role and searched-for role are both 0), so live access is partly inferred (observed and inferred). |
| Combo & Conversion | 72 | Present in 40 of 40 recorded combos at an average power index of 82.2, with example boards near 100, but the combo role fields are empty, so the conversion credit is an inference from board context rather than a measured role (observed and inferred). |
| Resource Economy | 45 | The text has a Ritual Summon with a Reptile tribute cost and a GY shuffle-to-Deck clause, with no draw or search; example boards show net card advantage of 4 to 5, which is a board-level figure and not card-level value (verified and observed). |
| Effect & Interaction | 5 | The card text has no negation, removal, or hand-trap clause, so it provides essentially no opponent interaction (verified). |
| Material Utility | 15 | It is a Spell and not a monster, so it is never material; its only tie to material is consuming Reptile monsters as tributes (verified). |
| Resilience & Flexibility | 40 | The guide notes that one Droll & Lock Bird shuts the deck down and that GY banish is a known weakness, which marks it as fragile against common interaction (observed from guide text, so tier observed). |
| Deck-Building Efficiency | 70 | Typically run as a single copy (1.08 average, 377 of 400 decks at 1 copy) with no garnet or brick noted; the Reptile-only restriction is the main cost (verified and observed). |
Calculation
Weight profile: Starter / Combo enabler weights (primary only); secondary Extender not blended because the combo evidence does not corroborate it. Intrinsic ≈ 50, Deck ≈ 54, Meta = provisional. Modifiers: Self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Appears in every sampled deck and every recorded combo, so the card is central to its deck
- Single-copy, cheap to run, with no garnet or brick cost
- Its GY clause can return it to the Deck, which gives some recovery
Weaknesses
- Spell with no direct interaction, no ATK/DEF value, and no material value
- Restricted to Reptile ritual targets and Reptile tributes
- Vulnerable to a single Droll & Lock Bird and to GY banish, according to guide text
- The combo evidence records no role for the card, so its exact conversion route is inferred
Counters / choke points
- Droll & Lock Bird (guide reports one copy shuts the deck down)
- GY banish effects (guide reports the deck is sensitive to them)
Best use
Ritual Summon engine that converts Mitsurugi Reptile tributes into a board. Decks: Mitsurugi (gameplay 7 and gameplay 4 variants), Mitsurugi with Ryzeal or Fiendsmith support. Suggested copies: 1.
Evidence & gaps
- Verified: Ritual Summons a Reptile Ritual Monster from hand or GY (card text); Requires Reptile tributes from hand or field with total Level at or above the target (card text); Each effect is once per turn (card text); Present in 400 of 400 sampled decks at 1.08 average copies (deck data); Present in 40 of 40 recorded combos (combo data)
- Observed: Average power index of 82.2 on boards containing the card (combo data); Mitsurugi archetype inclusion of 88 to 94 percent in usage statistics; Top-Card rank 84 in master-duel with 89.1 average percent (top-card data); Guide reports one Droll & Lock Bird shuts the deck down and GY banish is a weakness (guide data)
- Inferred: Card is the Ritual Summon engine for the Mitsurugi line, since its partners and examples are Mitsurugi cards; Live access comes mainly from the deck's own searchers, not from the card itself; The high power index reflects the surrounding board more than this card alone
- Data gaps: No banlist token; assumed 3 copies (unlimited) deck data matched by CardId, so the 400-deck sample likely contains only decks with this card; 100% inclusion and partner rates are not population rates combo data role counts (starter, searched, material, payoff) are all 0 and combo role is empty, so combo role cannot be confirmed No searcher or route data for the card itself usage statistics inclusion of 100 percent for several low-sample archetypes may reflect small denominators
