I understand that the process takes a really long time to be discussed and properly organized, but unfortunately the stupid DNA Splicers REQUIRE Kyurem to be caught before I can get them and I really want to start trying out Kyurem-W and -B so I need to catch him relatively soon (I play Wi-Fi obviously, lol). While EVs and moveset can be adjusted, Nature is stuck in stone so I'm trying to make a smart decision now. Adamant Scarf set seems most exciting to me now, and I find it encouraging that you believe it's one of the best.

Builds were sorted randomly lol, if you wanted to see full set order, you can wait for the Kyurem-B analysis in C&C which will be up at some stage, whih will look at nature, set order etc etc
