This is my personal favourite weatherless team at the moment, great work - it is not easy to concieve something that can stand up to the vast majority of current threats. I love not only the Zone-Mamo-Latias core but the secondary synergy of Gyarados and tinkerbell. I have used that combo and know how awesome it is - although I ran it with Moxie sub gyara. Have you tried Moxie or is Intimidate just too good for the team? Edit: Yeah I ran intimidate first but most of the stuff you switch gyara into can't really hurt it too much anyway (unless your bulkier spread allows it to get a sub up on physical attacks which can usually break the sub otherwise) while moxie often turns one turn of set up into a win, especially in rain.
