You could definitely use it if you want. Personally, I see nothing wrong with it that isn't a problem for all Eviolite users, other than its typing. It has a weakness to Ground, Electric, and Psychic type moves, all very common in NU. But it makes up with its resistances to Fighting and Water, which give it plenty of opportunities to come in and Spin.
Anyways, it has a awesome special defense, with a max of 492. But unfortunately, it has a not-so-good base 35 defense, that only reaches 277.5, allowing most neutral physical hits to destroy it with ease.
So it's up to you, Personally I think it could be OK, but look over the pros and cons yourself and make a decision.
