Nice team you got there. Have you tried using mega chomper over scarf chomp? You could use krook as your scarfer instead. Also, mamo and lando are both good ground types. have you gave them a shot?

well yes i have chosen all of those, but i find this team has done very well. 15 challengers have turned up and all of them have gone down so far. i'll think about the choices though ito thankyou very much
