How do anda get past Nimbasa City's gym leader with a Pignite, Gothia, Timber, Mincinco, and Lillipup?

What level are your pokemon? If anda want to beat the Nimbasa gym leader with the current pokemon anda have
anda can level them up, teach them strong moves. Timber should learn rock slide at level 31. anda can use that if anda could get that high to beat Emolga since it's a flying type. But be careful Timber is a fighting type. Flying type may beat your Timber. anda can't let that happen. Your Pignite can learn Rollout at level 23. The pindah only has power strength only 30. :( I guess anda could give that a try if anda want. For Zebstrika if anda have a dig TM anda can beat it oleh teaching your Lillipup, Timber, and Minnccino. atau instead of using the super effective type moves anda can try beat the pokemon with high powered moves anda can teach for now. Ex: Retaliate, Hammer Arm, Hyper Voice. Hope this works! :)
