Why it scores here

Secret Password is a pure archetype tutor: one Normal Spell activation converts into a 1-for-1 search of a "Live☆Twin" or "Evil★Twin" Spell/Trap, or - once both a Ki-sikil and a Lil-la are on board - into an "Evil★Twin" monster. Its score comes from reliability and deck centrality, not from any body: 400/400 sampled decks main-deck it at an average of 2.48 copies, and it is a 3-of in 100% of the Live☆Twin/Evil☆Twin archetype sample in usage statistics. It brings no disruption and no material of its own, and with 0 recorded combos the payoff into a board is text-inferred rather than measured. High stats are irrelevant here - the card has 0 ATK/DEF and earns nothing for them.

Axis scores

Axis Score Evidence
Accessibility 74 Costless Normal Spell played in 400/400 sampled decks at 2.48 average copies and 3 copies in 100% of the archetype sample; it is not itself fetched by the archetype's monster-search loop, so access is mostly draw-based (observed).
Combo & Conversion 66 The base effect fetches "Live☆Twin Sunny's Snitch", which itself searches a Live☆Twin monster, giving a one-card route into the engine, but combo data records 0 appearances so no board output can be measured (inferred).
Resource Economy 62 A straight 1-for-1 tutor whose fetched Sunny's Snitch searches again, so the chain trends even-to-plus; the card has no draw, refuel, or GY effect of its own (inferred).
Effect & Interaction 30 The card text contains no negation or removal at all; any interaction it produces is second-hand through the Evil★Twin Spell/Traps it can search (verified).
Material Utility 10 It is a Spell with no Level, Attribute, or body, so it cannot be used as material for any Summon and contributes nothing when its effect is blanked (verified).
Resilience & Flexibility 45 One activation per turn, no protection and no GY follow-up mean a negated activation is a minus-one that is dead for the rest of the turn; flexibility is limited to choosing the search target (inferred).
Deck-Building Efficiency 68 Slot cost is low (2-3 copies of an in-archetype Spell with no garnet beyond cards the deck already plays), but the card is completely dead in any deck that does not already contain Live☆Twin/Evil★Twin cards (observed).

Calculation

Weight profile: 0.7 Searcher/Tutor + 0.3 Starter/Combo enabler. Intrinsic ≈ 57.7, Deck ≈ 64.9, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Unconditional, costless search of the archetype's Spell/Trap line with a built-in upgrade clause once both twins are on board
  • Extremely high real-world inclusion: 400/400 sampled decks main-deck it, 100% inclusion at typically 3 copies in the Live☆Twin/Evil★Twin archetype sample
  • Fetches "Live☆Twin Sunny's Snitch", converting the card into an extra one-card route into the Live☆Twin engine
  • Enables the second mode that tutors an "Evil★Twin" monster directly once a Ki-sikil and a Lil-la are controlled
  • Appears alongside the entire Live☆Twin/Evil★Twin core at 97-100% co-occurrence, confirming it is a genuine core piece rather than a tech slot

Weaknesses

  • Zero interaction: no negation, no removal, no disruption on its own
  • No body, Level, or Attribute - it can never be used as material and is worthless once its effect is negated
  • Hard-locked to Live☆Twin/Evil★Twin cards; completely dead outside those decks
  • One activation per turn with no protection or GY follow-up, so a negated activation is a minus-one with no recovery
  • No combo evidence exists (0 appearances), so the strength of the resulting board is not measured

Counters / choke points

  • Ash Blossom & Joyous Spring (negates the add-to-hand)
  • Droll & Lock Bird (restricts the follow-up searches the fetched Sunny's Snitch would perform)
  • Called by the Grave and similar hand-trap removal (negates the search and removes the resource)
  • Generic Spell/Trap negation such as Solemn Judgment or a negating board piece
  • Hand knowledge effects that strip the fetched Sunny's Snitch before it resolves

Best use

Archetype searcher / consistency starter that fetches Sunny's Snitch or an Evil★Twin monster. Decks: Live☆Twin, Evil★Twin, Evil Twin / Fiendsmith, Spright Evil Twin, Unchained Evil Twin. Suggested copies: 3.

Evidence & gaps

  • Verified: Card text: Normal Spell that adds 1 "Live☆Twin" or "Evil★Twin" Spell/Trap from Deck to hand; if you control a Ki-sikil and a Lil-la monster, you can add 1 "Evil★Twin" monster instead; Card text contains no negation, removal, or material-relevant stats (0 ATK / 0 DEF); Card text: 'You can only activate 1 "Secret Password" per turn'; 400/400 sampled decks run it in the main deck (0 in side), average 2.48 copies
  • Observed: Copy distribution in the sample: 245 decks at 3 copies, 104 at 2, 51 at 1; Co-deck partners are the full Live☆Twin/Evil★Twin core at 97-100% co-occurrence (Ki-sikil, Lil-la, Sunny's Snitch, Trouble Sunny, Ki-sikil Deal, Lil-la Sweet); Spread across 16 distinct archetypes, including Fiendsmith (26.8%), Unchained (10.8%) and Spright (9.5%) samples; Usage statistics: 100% inclusion at typically 3 copies in the Live☆Twin/Evil★Twin archetype sample; 57.1% in Knightmare, 45.5% in Spright, 40.6% in Evil Twin samples; combo data records 0 appearances - no measured starter/material/payoff usage
  • Inferred: Base effect fetches "Live☆Twin Sunny's Snitch", which then searches a Live☆Twin monster, making the card an additional one-card route into the engine; Second mode converts into an "Evil★Twin" monster once both twins are on board, extending the Link climb; No protection and no GY effect: a negated activation is a minus-one and dead for the rest of the turn; It is not itself fetched by the archetype's monster-search loop, so access depends mainly on drawing it
  • Data gaps: no combos supplied - combo conversion is text-only inference no banlist token - assumed 3 copies (unlimited) no dated metagame sample, so meta power is null/provisional no measured board power index for decks running the card deck data does not split results by format, despite the card being listed as legal in TCG, OCG, Master Duel and Duel Links
