>>55207022Lots of good ones in here. I'd personally pick Venusaur (beam/sludge). Don't forget to enable the "camera follows moves" setting.
Blastoise, A9, Gardevoir, Crustle are all not that hard to use and can work really well.
But TBQH almost any of these is fine as long as you know what to do and what not to do. Sylveon is low on the meta pole, but I really enjoy it, for example.
