I'm having some trouble against Corey: more specifically, his Crobat. I can beat his other five Pokemon without much problem, but his Crobat just one or two-hit-KOs my Pokemon with Venoshock. 
 
	Any suggestions on how to prepare myself, whether it's by items, new Pokemon or new moves are appreciated.
