That's tough, man... My condolences to you, wish you the best in this moment.
About movepool (STABs mainly) and stats, what do you think the starters are gonna get?
Assuming the leaks are real, Popplio3 and Litten3 seem pretty obvious to me, the first being special based, getting the regular special Water and Fairy moves, and the last being physical based, getting the fire moves we all know, and dark moves like Feint Attack, Bite, Crunch, Knock Off.
But about Rowlet3 i'm not so sure. I can see it going both physical and special. If physical, the most obvious attacks would be Razor Leaf while leveling up, and Leaf Blade being it's most notorious STAB. At first i thought it would be weird, but nobody said that Blade must be a melee weapon. Oh, Petal Blizzard fits too. About flying moves, most of them makes sense, and as its strongest options, both Acrobatics and Brave Bird would work. For setup, Swords Dance would look weird, but whatever.
Also, Sniper makes a lot of sense for a Hidden Ability, and would benefit a physical Rowlet3 greatly.
If it goes special, on the other hand, i guess Magical Leaf, Leaf Tornado and Leaf Storm. Special flying moves are always a problem, it could get Gust at first, then Air Cutter, then Air Slash. Hurricane is awesome as well, but that accuracy is lame. That way, if it got an ability to help with its accuracy, it would be awesome. No Guard fits, Compound Eyes would be useful but is more related to Bugs. It could get some ability with the same effect, but with a different name. Something like Sharpshooter, Bullseye, or anything like that.
