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

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