When your opponent activates a card or effect: Target 1 "Libromancer" Ritual Monster you control; return it to the hand, and if you do, negate that activated effect, then you can Special Summon 1 "Libromancer" monster from your hand or GY. You can only activate 1 "Libromancer Intervention" per turn.
Libromancer Intervention — Power Evaluation
Final Score: 55 ± 8 · Confidence: Medium
- Intrinsic: 55 · Deck: 55 · Meta: provisional
- Primary role: Negation/Interaction · Secondary: Recovery/Recursion
Why it scores here
The card's value is a broad, once-per-turn negate of any opponent activation, paid for by bouncing a Libromancer Ritual monster that it can then Special Summon back from hand or GY, so it converts one interaction into a negate plus a recycled body. It is conditional on a Libromancer Ritual monster already being on the field, which caps accessibility and resilience. The 400-of-400 deck presence and 100% partner rates come from a sample matched on this card's CardId and are not treated as evidence of strength; the 55 rests on card text and archetype fit, with no combo data to confirm conversion.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs a Libromancer Ritual monster on the field when the trap activates; the card is a Trap Card and the decks sample shows it in Libromancer shells (inferred from text, deck data archetype spread, 100% partner rates are sampling artifact) (inferred). |
| Combo & Conversion | 50 | Negate plus Special Summon of a Libromancer from hand or GY is a one-card extension of a board, but no combo data was supplied so conversion rests on text alone (inferred). |
| Resource Economy | 60 | Bounce-to-hand is a cost that is recovered by the Special Summon, so the card is roughly card-neutral to slightly positive with no card lost (inferred from text). |
| Effect & Interaction | 70 | Negates any activated card or effect, with the restriction only that the activation is an opponent's card or effect, which is a broad, flexible negate (verified from card text). |
| Material Utility | 10 | A Trap Card has no monster body, so it provides no material, level or attribute value (verified from card type). |
| Resilience & Flexibility | 45 | Once per turn, depends on a Libromancer Ritual monster on field, and is vulnerable as a set trap to backrow interaction (inferred from text and type). |
| Deck-Building Efficiency | 60 | A single slot with typical 1 copy (usage statistics typical copies 1, copies per deck avg 1.1) and no garnet, but it is restricted to Libromancer-style decks (observed from deck data and inferred from text). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Recovery/Recursion. Intrinsic ≈ 55, Deck ≈ 55, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Negates any opponent card or effect activation, not a single named card type
- Negate is paid for by a Libromancer Ritual monster that it returns to hand, which can be Special Summoned back from hand or GY
- Typical 1-copy slot with broad inclusion across Libromancer archetype variants
Weaknesses
- Needs a Libromancer Ritual monster on the field at activation, so it is dead without that board state
- Once-per-turn name restriction limits repeated use
- Set trap: vulnerable to backrow removal before it is used
Counters / choke points
- Backrow removal or effects that destroy set Traps (inferred from card type)
- Opponent actions that remove the Libromancer Ritual monster before activation (inferred from cost)
Best use
Negation with recursion inside a Libromancer shell. Decks: Libromancer (archetype_id 855, 1131, 2271, 1183), Mikanko, Dogmatika, Nouvelles. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: negate of a targeted opponent activation, return of a Libromancer Ritual monster to hand as the cost, Special Summon of a Libromancer from hand or GY, once per turn by name; Card type is Trap Card; no monster body; Average 1.1 copies per deck; typical copies 1 across the 4 usage archetypes
- Observed: Presence in 400 of 400 sampled decks, 54 distinct archetypes, with Libromancer archetype IDs dominating; Gameplay type 7 holds 54.2% of decks; Partner co-occurrence of 100% with Libromancer Doombroker, Libromancer Fire, Libromancer Geek Boy, and Libromancer First Appearance
- Inferred: Accessibility is conditional on a Libromancer Ritual monster being on the field; Negate-plus-recycle gives roughly neutral to positive resource economy; Set-trap vulnerability to backrow removal; Score is driven by text and archetype fit, not by deck frequency
- Data gaps: No combos supplied: combo conversion, starter/material/payoff roles and power index are text-only inference The 400-of-400 deck presence is likely an artifact of a sample matched on this card's CardId, so frequency cannot separate staple use from sampling No banlist token: assumed 3 copies (unlimited) No rulings or Rush-specific data No top-card data ranking
