i use blissey to counter both cradily and wailord at the same time, which very few pokemon can do. take a look at the "infamous" kgstall with defensive behemoths: hippowdon cannot, forretress cannot, rotom-h cannot, tyranitar cannot, gyarados cannot, kg's blissey is a stupid set and cannot. for this reason, i recommend you use my set:
charm, calmmind, softboiled, icebeam/grassknot
good luck with your team.
