Sawsbuck is definitely my favourite out of the ones that dropped. Amazing speed and attack for the tier, great movepool and great support options as well as two amazing abilities. Ludicolo is quite a funny one in that it acts as a great abuser and, at the same time, a great counter/check to rain. +2 Ludicolo is also annoying fast and bulky for scarfers in the tier to check, there aren't that many Pokemon that can take it on through resistances so I hope we're not all forced to use Lickilicky to counter it.
Charizard is a real wildcard for me, I tried using it before in RU and it really really needs support. The conditions for it being able to fire off ridiculous Fire Blasts is: Sun needs to be up, it must be near full health or else SR must not be up, it must switch in safely and outspeed the opponent. When those factors are considered it's not easy to fit it onto a normal team; dedicated Sun teams will love it but it has to watch out for Flash Fire Pokemon too because that will take the wind right out of its sails. I don't expect Charizard to be a popular choice on teams simply because how hard it is to use but I fully expect it to emerge in some top teams because it is extremely deadly.
