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

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