Why it scores here

Hidden Spellbook is a recursion card: it shuffles two Spell Cards from the Graveyard back into the Deck, so it converts spent Spells into future draws rather than generating advantage or board presence. Its score sits in the mid-40s because the effect is conditional on having two Spells in the Graveyard, it has no opponent interaction, and it is not a monster and so offers no material value. Its high deck count (10 of 10 sampled decks running it, 1.6 copies on average) supports real accessibility and a cheap, clean slot, but frequency alone does not raise the score. No combo or guide evidence was supplied, so combo conversion rests on the card text alone.

Axis scores

Axis Score Evidence
Accessibility 45 Live in 10 of 10 sampled decks across 9 archetypes, but the effect needs two Spell Cards already in the Graveyard, so it is not reliably live on turn one (observed; the Graveyard requirement is verified from text).
Combo & Conversion 30 Text only: it recycles Spells into the Deck and builds no board on its own, and no combo boards were supplied to confirm a line (inferred).
Resource Economy 45 Returns two Spells from the Graveyard to the Deck, a refuel that recovers resources without drawing or adding a card (verified from text; the refuel value is inferred).
Effect & Interaction 10 No opponent-facing effect in the text, so it offers no negation, removal, or hand-trap reach (verified from text).
Material Utility 5 Trap Card with no monster body, so it cannot be used as material (verified from card type).
Resilience & Flexibility 35 Single effect, a Trap card that can be removed from the field or targeted out of the Graveyard before it resolves; no redundancy evidence was supplied (inferred).
Deck-Building Efficiency 65 Runs 1 to 3 copies per deck (average 1.6), in the main deck only, with no garnet or self-lock restriction (observed; the no-lock point is inferred from the text).

Calculation

Weight profile: 0.7 Recovery/Recursion + 0.3 Utility (secondary). Intrinsic ≈ 44, Deck ≈ 46, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Cheap, single-copy-friendly slot used in 10 of 10 sampled decks
  • Recycles spent Spell Cards into the Deck, improving later access to Spells
  • No garnet or self-locking restriction on deck building

Weaknesses

  • No opponent interaction or board presence
  • Needs two Spell Cards in the Graveyard before it does anything
  • Not a monster, so it has no material value

Counters / choke points

  • Inferred: Graveyard-hate or Spell-banish effects can remove the two targets before the effect resolves, shutting it off

Best use

Recovery/Recursion support for Spell-heavy decks. Decks: Spellbook (archetype 894), Spellbook (archetype 782).

Evidence & gaps

  • Verified: Card text: during your turn, target 2 Spell Cards in your Graveyard and shuffle them into the Deck; Card type Trap Card, no monster body, no ATK/DEF or link data; Legal in TCG, OCG, MasterDuel and DuelLinks; banlist assumed unlimited (3)
  • Observed: Present in 10 of 10 sampled decks, all in the main deck, 1.6 copies on average, max 3; Spellbook Organization co-occurs in 5 decks (50%) and the Prophecy suite co-occurs in 4 decks (40%); No combo appearances recorded and no guide mentions
  • Inferred: Refuelling two Spells into the Deck is a recovery effect with no direct card advantage; The Graveyard requirement limits early-game reliability
  • Data gaps: No combo boards supplied, so combo conversion and starter/searched roles are text-only inference No guides supplied No usage statistics (StatisticsCard) for inclusion % beyond the 10-deck sample No banlist token, so unlimited copies assumed No rulings or trap subtype (Normal/Continuous) supplied to confirm activation timing No top-card ranking data
