Keep working on it! I think you need some kind of Support Pokemon... I'm going to get one myself. This is what I'll be doing: feel free to do the same.
Drapion
Focus Sash
EV'd in Defense, Sp. Defense (First time EVing)
Toxic Spikes
Roar
Poison Fang
Ice Fang/Crunch
Strategy: Two toxic spikes, then Roar to switch my opponent's Pokemon and Badly Poison them. Posion Fang as main offensive attack; Ice fang in the case of coming across a ground type, Crunch in the case of a Psychic type.
