I would recommend training Kricketot as spamming Fury Cutter can knock out most her pokes once used repeatedly. Another option could be Trubbish who can lay down T. Spikes and just spam Acid Spray as well. However, for the Cradily, a Fighting type like Mankey and Makuhita can take it on pretty well.
Thanks for the help, but what level should I train kricketot to?
