Crystal Rush

My delta metagross (ruin) learned a move called crystal rush with no accuracy or power and the description just says 000. Does anyone know what it’s suppose to do.

No, it’s bugged.

I think it’s working now, it’s a rare move, though. It’s a priority move but with no type effectiveness. I’ve used in battle with no bugs so far. Also, it doesn’t make D. Metagross ruin change its look.

That’s because there’s no backsprite.
