"Dust Barrier" Rating Score by みめっと

While this card is on the field, the Normal Monster can gain complete resistance only to his opponent's spells, and this can increase his status with his own spells, grant additional resistances, etc. You can, but the time is limited due to the self-destruct disadvantage.
But more than that, even with a deck that currently has a lot of spell cards, its role is to draw, search, GY fertilize Special Summon type cards, and the rest is mainly splitting back and designating. It's not uncommon for cards that directly affect a monster to have a drop or two, so the benefits of being immune to spells are smaller than you might think.
Monster removal Spell, monster back defense Spell, control seizure Spell, weakening/attack limiting system Continuous Spell, etc. are all basically cards that are difficult to contribute to the rotation of the Deck in the first attack, and gain resistance. Since it is a Normal Monster, there is no point in using a spell that negates a monster effect in the first place.
Even in 2022, the imperial order is a matter of course, and even though P isn't the top player in the environment, Kaori is still a regular on the side. .
