"One-Eyed Skill Gainer" Rating Score by 戦士族大好き

In a paper card game where you can't easily errata or hand out correction patches, copying names and effects is one of the few ways that old cards can catch up with the latest cards and is valuable.
Well, this card has such a name + effect copy, but in Yu-Gi-Oh, "What is a strong effect that you want to copy?"
I think the biggest problem with this card is that it can only target Xyz monsters "on the opponent's field", not the material weight.
In Yu-Gi-Oh, strong effects that you want to copy with your opponent's monsters are trigger effects such as "negate and destroy effects", removal of free chains, and other things that suppress or interfere.
In other words, the process of playing this card and activating this card's effect will apply the above effects, so the card can't be put into play, or it will be easily removed. .
That's all there is to it, but it's still barely a 4-point evaluation, but it's unavoidable that "Number 69: Heraldry Crest" has solved these problems to some extent.
It has the same status as LIGHT, the same rank 4, and it's simple, with ATK 2600 and Ace RBI, it's also a 《No.
As an added bonus, you can also target your own X monsters, so you can use it as a combo card.
Differentiate by race! That's why it's impossible.
As written on the external wiki, one of the few evaluation points of this card is that the effect copy is permanent.
《Kikinagashi Fucho》is easy to put out, but it has complete resistance, and the copy effect only targets it, so it can be copied.
《Kikinagashi Fucho》's weak point, its low status, can be compensated for by this card's status, and it can withstand battle destruction once.
My trick is to use "Branded Expulsion" to put "Kikinagashi Fucho" on the opponent's field and copy it, but it's too much of an empty theory, and I'm frustrated to write it.
Isn't there a convenient card where you can put an X monster on your opponent's field and get some extras?
