Anticipation / Infiltrator / Unnerve
Hullo. First contribution to a CAP project, so I'm trying to be smart about this.
I think a better set of abilities would be, as many others are saying, these three. Anticipation gives good alert to potential Earthquakes/Stone Edges that would really hurt this pre-evo, Inflitrator lets you deal with sub walls, and Unnerve would probably be amazing on a status-setting build, allowing this pre-evo to gleefully set up Will-O-Wisps and Toxics without worrying about a potential Lum Berry, leaving the only counters being Pokemon with Natural Cure, Shed Skin, Heal Bell, etc.
