Are you missing an 's'?
Anyway, Crobat is fine but its movepool is really bad if you try and get it early. Later on, 90 base attack is a fine stat to use Sludge Bomb and Wing Attack off but a slightly larger move pool would be nice. It can only really use Sludge Bomb, Wing Attack, Steel Wing and Shadow Ball as a movepool, and that doesn't really give the best coverage for three TMs worth. I guess it could use Giga Drain but it's so weak off 70 Spattack you might as well just Sludge Bomb whatever it is.
