"Grand Spiritual Art - Ichirin" Rating Score by TK

First of all, the point to note about this card is
"If you put it out for the time being, it will almost unconditionally lead to add, solve accidents, and lead to powerful development and interference."
It's not that kind of card.
The search effect is very good (for Charmer)
I'm thankful for the Charmer Deck, which tends to duplicate Familiar-Possessed and Charmers in hand, which is practically vanilla.
Since the obstruction effect is visible, the surprise attack is low, but I would like to cover it with 《Possessed Partnerships》. The range is wide and strong, and it is strong.
However, in the current environment, the hand trigger system that has high versatility and can interfere with the first move, the grave of unparalleled response even if the first move is useless, and the three battles that can be cheated after seeing the effect are fine. After all, the field is 《Secret Village of the Spellcasters》, and he is stronger if he shuts out spells and throws around. There is also a method of surprise attack with Metabar, but then it is said that it is okay to use them normally at the timing of using Metabar. By the way, it's an automatic activation, so if you shoot the effects that you don't want from the opponent first, the rest will pass. (Example: Expand after throwing increased G with free chain)
I have to say that it is quite mild for a recent theme field.
It is safe to assist in slack processing with 1-2 stacks. If you put 3 copies of this and double in the first hand, it will be a big accident on the field to solve the hand accident. In theme construction, it became necessary to introduce advanced Familiar-Possessed familiars, so it is even more difficult to balance accident prevention.
Wouldn't it be safer to put in 2-3 terafos that can be exchanged for both depending on the situation?
