Terrors of the Underroot →Used Deck

A Trap that swaps GY and excluded cards. Since he can only choose the same number of GY and the number of exclusions itself does not change, he can choose all the targets by himself and can target all monster Spell Traps, so the most convenient exchange is possible. Since the target is "up to 5", it's OK to exchange one at a time, and of course it's a free chain (although there is a limit of two targets), so it's surprisingly effective in a tight turn.
The essence of this card is the niche role of "can interfere with resurrection and return", which is the result of combining these. No other card has the disgust to make a friendship combo with both self-regeneration and temporary removal. Of course, you can actively move around 《Banquet of Millions》.
However, in reality, decisive timing rarely comes around, and rivals such as Crow, which is less disturbed and easier to measure timing, and Genmai, which can be used for active combos, are far behind.
Even if he can get his hands on both GY exclusions, his Deck that utilizes both is limited, so adopting a card that sticks more effectively to one or the other will likely lead to better results. depends on the environment.

Comprehensive evaluation: To the extent that it can be used if the opponent excludes it with 《Pot of Desires》or 《Pot of Prosperity》.
You can cut up to 5 of your opponent's GY resources, but you also need the number of banished cards.
It doesn't make sense to actively remove a card from his GY, such as The Phantom Knights, and return a card that can use its effect.
You can also choose cards that have been removed from the backside, so if you return them and remove them, you can aim for some interference, but in the GY meta there are also 《Ghost Belle & Haunted Mansion》and so on.

It's his GY meta and exclusion meta that swaps the opponent's GY and exclusion, but it can't be activated unless there are cards in both.
Replacing is a curse, and even if he excludes resources from GY, there is a possibility that other resources will be replenished from the exclusion.
In the GY meta, Crow and Grave, and in the exclusion meta, Burial from a Different Dimension is easier to use due to greed and different dimensions, so there aren't many situations where this card has to be used.
As already said, if you can target your boyfriend's GY or exclusion zone, it would be much easier to use...

The main method of operation is probably to interfere with the opponent's GY and exclusion use, but as a premise, it can't even be activated unless there are cards in both the opponent's GY and exclusion zone, and depending on the opponent's Deck. I can't even use it satisfactorily. It's a side card.
If you want to block the use of GY, in the first place, DD Crow, which has faster effects than this card and can be used even if the opponent goes first, is often sufficient, and if you want to block the use of exclusions, Burial from a Different Dimension, which also has immediate effects and can be used on yourself, is sufficient. .
The unique advantage of this card is the large number of targets, the dexterity regardless of the type of card, and simply returning it to his GY, "exchanging" rather than excluding it, but the latter seems to be taken advantage of There will also be scenes.
It would have been much more convenient if I could target his own GY Exclusion Zone, but this alone would be a poor card.
The illustration ad is very expensive, so I want to give a perfect score for collection.

A trap card that exchanges up to 5 opponent's GY cards and excluded cards equivalently.
As a Friche, he can handle both GY use and exclusion use, and it can be said that he can fulfill his role as a meta even if he doesn't care about the maximum number.
However, for example, even if one card is exchanged, it is rare for both to be a card that you don't like if they are in GY and a card that you don't like if they are excluded. If you don't use Crossout Designator》, your opponent may not have the means to banish their own cards.
If you just want to use it as a GY meta, he has many cards that are better than this card, starting with D/D Crow, so I want to think about it carefully.
It's also worth noting that you can target cards that have been banished behind the scenes, as well as Spell Trap cards.
