Libromancer Intervention →Used Deck

Theme-specific all-purpose negate Trap.
However, since it is "not a Counter Trap" and "only negates the effect", it is often useless against "Field Spell, Continuous Spell, Continuous Trap" opponents. (because you don't have to).
On the other hand, I think it's a good card that's balanced and not overly strong.
Also, with the effect of Libromancer Doombroker, he can be set from the Deck, so it's also great that it's not interrupted by Ash Blossom & Joyous Spring.
When this card is activated, his Ritual Monsters on the field will be returned to his hand, but since Libromancer needs Ritual Monsters in his hand for deployment, it is not an add loss. At the same time, his GY monster can be revived, so it's well designed to be connected to the development of the next turn.
Libromancer itself can be deployed without using summoning rights, so it is easy to mix with other themes to some extent, and for the theme that wants a universal negate trap, it would make sense to mix construction by itself.
"Normal Trap leaves the monster out of the field", so it seems like it can be used with 《Labrynth》, but it's hard because it's affected by Field Spell.

Traps that are mainly set with 《Libromancer Doombroker》.
The Ritual Monster that was returned to the hand at the cost can be used for a sneak peek on the next turn, so it's not as big a disadvantage as it looks.
If you send a low-level Libromancer from GY, you can also search with the effect.

A versatile negate card that can be easily set with 《Libromancer Doombroker》. When you activate it, you will mainly return Death Broker to your hand, but if possible, place Maji Girl next to Death Broker, and use Misty Girl to neutralize the opponent's monsters. It would be ideal if you could return Misty Girl to your hand while interfering with the opponent's subsequent actions with this card.
However, it should be noted that it is a Normal Trap, which is rare for a card of this kind, so unlike Counter Trap, it leaves room for the opponent to respond.

By returning the "Libromancer" Ritual Monster to your hand, you can negate the activation of all effects and optionally resurrect the "Libromancer" monster, which I think is excellent.
I think that being able to set from the Deck with 《Libromancer Doombroker》is also a strength.

One of the strongest Trap cards with all-purpose negate (Spell, Trap, Monster effect) + resurrection effect. Since it can be set directly from the Deck with 《Libromancer Doombroker》, it is easy to set up as a 1-interference.

Comprehensive evaluation: Advantage can be greatly earned by resuscitation in negate-ization.
Set with 《Libromancer Doombroker》, and you can activate it by returning it.
At that time, you can also revive, and it is said that you can revive 《Libromancer Fire》and so on to search and earn an advantage.
The returned Ritual Monster will also trigger his Libromancer's Special Summon, so it won't be difficult to Ritual Summon again.
