Moon: To start with, I continued with the EV-training and completed it. Made a mistake while EV-training Hawlucha as I accidentally trained it in Speed instead of Defense, but that was easy to fix. There is a reason I always carry lots of EV-reducing berries with me, you never know when you might need them. Once all four Pokemon were done, I gave them Effort Ribbons, then I played with them in Pokemon Refresh to max their affection.
After that, I got started on the training. The goal is to get Metang and Hawlucha to level 50, Deino to level 64 and Tapu Lele to level 100. It might take a while, but hopefully not too long. So far, I have gotten Metang, Hawlucha and Deino to level 30 through regular training. As for Tapu Lele, I took it to my Rare Kitchen in Festival Plaza, let it eat a lot and it has grown to level 88 so far, which is good. I let it battle Morimoto while holding the Lucky Egg and it got about half of the Exp. it needs to get to level 89. Going to continue training all four until they are at their desired levels.
Sun: Continued with the training here. Battled Morimoto, took on the Infinity Battle Buffet and battled many wild Pokemon. Several things happened along the way.
Kihunter learned Superpower at level 67, which means that its moveset is complete.
Most of the time, I have been keeping Radiant Nova in my party while using other Pokemon for the actual battling. It has gained a ton of Exp. in the process, most notably when I have been battling Morimoto. It eventually evolved into Cosmoem, and now there's not much left until it is fully evolved!
I raised the Friendship level of Diet Crasher until it could learn Draco Meteor, which completed its moveset. It also grew to level 72, which means that it is done.
Lionheart learned Flare Blitz at level 61, its moveset is now complete as well.
Sunspot reached level 76 and is done too.
Shadowcastle learned Giga Drain, Shadow Ball and Earth Power, as well as evolved into Palossand! Which means it is quite a bit more powerful, and that's great.
That's about it so far. All current members of the squad are now above level 50, which is great. It means that this will probably not take anywhere near as long as I had thought at first. Though I still have quite a bit left, but it will be done eventually.
