"Soul Exchange" Rating Score by シエスタ

It is a card that can raise the release cost with monsters on the opponent's field, and since it is a release, it can remove most resistant people, so it is a high quality removal.
However, it has the heavy disadvantage of not being able to battle phase. It's a little painful that it's hard to handle offensively even with a special removal.
Although it will be limited to Tribute Summon, a powerful rival named Retsusen has appeared. The downside is that it doesn't matter as much depending on his deck, and it doesn't feel as heavy as this one. After all, it is great to be able to immediately make use of advanced RBIs, which often have high RBIs.
And even in terms of being able to use it to release effects, there's even a shadow dystopia. It's a field over there, so it doesn't wear out.
His selling point is that he can use both elements of Retsusen and dystopia, but he can make use of both and he doesn't care about the disadvantages, so he can't even think of a deck and ends up giving a half-hearted impression. Furthermore, compared to the above two cards, the search means is also thin.
I think it's a strong card. However, it's not that the effect itself is weak, it's just that it's less useful than the above two, and basically it's mainly used as the 4th one.
