If you add the base stats on a 10/10/10 kyogre to its IV and do the same for a perfect kyogre, the difference is 2%. So, if this one is truely the only one you will get, power it up and enjoy it. I've been using WF/T kyogre against kyogre, but in most cases, it would be better, if you could eventually CTM to hydropump.

WF/T Kyogre
I have a 80IV 11ATK WF/T Kyogre. I probably will not be able to get another one (i live in a very rural area) and i have no CTM. Would WF/T be good against Water/Flying type legionaries such as Moltres and Ho-Oh. Would you power this Kyogre up or CTM it or should I wait for a better one?
