Kyogre and Arceus-Water outclass Blastoise-Mega, unless you go with a Shell Smash set, which while it isn’t meta is a neat choice you could go with. Use things like Necrozma-DM and Yveltal to back it up.
Hello, normally I do not comment in rmts unless I have got to lock them or I am actually rating. As we can see the one liners back and forth are not getting this thread anywhere. This is why we prefer thought out and organized rating. I can see the trouble with the op claiming this as an AG team when it was clearly not meant to be one, but when rating this is why back and forth doesn't work.
