How do I counter rotom?

Over Internet battling, I find that a lot of people use rotom. I find trouble in these cases and most likely lose that match. How do I counter it?

Ps. Most people who uses rotom have heat or wash forms.

Rotom-W

Basically any bulky grass type will do the trick. Celebi, Roserade, Trevenant, you name it. They resist both STABs and most take little damage from HP Ice, although species that lack Natural Cure and are physical should watch out for Will-O-Wisp. Gastrodon also does a very fine job as it immune to both of it’s STAB moves and doesn’t care about a Will-O-Wisp or HP Ice. Dragon types deserve a mention to as they resist both STABs, but the 4x weak ones will hate HP Ice.

I’ll do Rotom-H later.

A Rotom (wash form) has one weakness: Grass; however, Rotom (heat form) resists grass as it is part fire. Therefore, you need to use a ground type move, (after their ability is surpressed to get rid of levitate) as ground is the only weakness they have in common. I would suggest using Excadrill, as it has mold-breaker to negate levitate, then hit them hard with STAB earthquake.

An Excadrill with mold-breaker can be found in the friend safari, in Steel types.
