Why it scores here
Libromancer Prevented is a Continuous Trap whose only interaction is a once-per-turn denial: while you control a Libromancer monster, one face-up opponent monster cannot be used as material for a Fusion, Synchro, Xyz, or Link Summon this turn. It does not build a board, refuel, or leave a body, and its self-send at End Phase earns nothing. Its low archetype breadth and the Libromancer-board requirement cap its score, so the strong deck presence (41 sampled decks, 27 in the main Libromancer archetype) confirms it is a live, cheap slot rather than raising its power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs a Libromancer monster already on the field to activate, and it is a trap that must be set first; the deck evidence shows it in 41 of 41 sampled decks, all Libromancer-led (verified deck stat, inference on the board requirement). |
| Combo & Conversion | 15 | No recorded combos (starter role, material role and examples are all zero), so conversion is text-only: it denies material and builds nothing (inferred). |
| Resource Economy | 25 | No draw, search, or GY refuel; its End Phase clause sends itself to the GY, a cost with no return (verified text). |
| Effect & Interaction | 40 | A once-per-turn material denial on one monster for one turn, which is soft interaction against Extra Deck summons only (verified text, inferred strength). |
| Material Utility | 5 | A Trap card cannot be used as material, and the effect does not change that (verified text). |
| Resilience & Flexibility | 35 | Sits face-up on the field and can be removed by ordinary card effects; its effect is single-use per turn and needs a Libromancer on field (inferred). |
| Deck-Building Efficiency | 70 | A single slot with typical copies of 1 and no garnet or lock restriction; the archetype dependence is the only cost (verified deck and usage stats). |
Calculation
Weight profile: 0.7 Floodgate/Control + 0.3 Utility (secondary). Intrinsic ≈ 42, Deck ≈ 44, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Denies Extra Deck material for one turn, a soft interaction hard to use against a set-up board
- Cheap single-copy slot that sits in a deck with every Libromancer partner (41 of 41 sampled decks)
Weaknesses
- Needs a Libromancer monster on field to activate, so it is dead without that board
- Once per turn for the denial and it only hits Extra Deck summons, not Normal Summons or Special Summons from hand
- No card advantage, refuel, or board presence; the End Phase clause sends it to the GY
Counters / choke points
- Trap removal or negation on the set card
- Extra Deck summons that do not use the targeted monster as material
Best use
Floodgate/Control: one-turn material denial against Extra Deck engines. Decks: Libromancer (archetype 855, 27 decks), Libromancer (archetype 1131, 4 decks). Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Continuous Trap, once-per-turn material denial for Fusion/Synchro/Xyz/Link, End Phase self-send if no Libromancer Ritual monsters; 41 sampled decks run it, 1 copy average-ish (avg 1.29), 27 in archetype 855; Usage stats: inclusion 100% in 3 gameplay-6 archetypes, typical copies 1
- Observed: Co-occurs with core Libromancer partners in 100% of sampled decks; Main-deck in 41 of 41 sampled decks
- Inferred: Denial is soft interaction because it only hits Extra Deck summons for one turn; Trap removal and set-state vulnerability are plausible but not tabled
- Data gaps: no combos supplied - combo conversion is text-only inference no banlist token - assumed 3 copies (unlimited) no rulings or interaction data for the trap being negated or destroyed no RulesReliability source beyond text
