well Crawli is a double battle bug gym leader with a pre-set rain making him actually strong with fire type (Shelly PTSD), buuuuuuuuuuuuuuuuuuuuuuuuuuut he still have no rock/flying /poison coverage or those coverage is kinda slow/ frail. Dusk Lycan is the best option since Accel, rock slide. If you want to take advantage of the rain, Togedemaru and maybe pikachu can be useful with his dewspider. and lastly, you can change the field by getting a torkoal with drought as lead or get use both Dusk Lycan and Solrock then Rock slide spam... with A-Muk behind them if accident happen.
