Meowth can't do shit to dedicated walls, while Buneary effectively eliminates them.
That's a bit harsh... Aipom has better stats and way more coverage moves (Seed Bomb, Acrobatics (!), and U-turn are the big ones). It can also Baton Pass Nasty Plot, which is sorta unique I guess. Buneary has Klutz + Switcheroo and Encore going for it, which I guess with 19 Speed is pretty good, but not entirely outclassing Aipom. Aipom might be a bit weaker than Meowth, but it is much bulkier and has way more coverage options (Meowth just has Bite, Seed Bomb, and U-turn.)^ Aipom doesn't have Technician, meaning it is entirely outclassed by Buneary.
I've had a tough time facing a Wish-Protect Lickiting, luckily on like the 10th try my focus blast critted.Lickitung doesn't have to run rest talk, in fact i found it to be a decent cleric since it gets wish and heal bell. Restoring 14 points of an allies hp which is very helpful for "insert pokemon with 19 hp for Life Orb recoil" and it can still be a pretty decent tank that can take hits with its base 90/75/75 defenses. Sadly it cant use wish or heal bell with cloud nine so it has to use the lesser own tempo.
Snivy does lack reliable recovery outside of leech seed (which isnt very reliable) and rest, but if it does go for rest it can take a defensive route to utilize the fact it gets coil or cm, but in my experience, the coil one has often been set up on by dd scraggy. The calm mind variant suprises people and it isn't too physically frail to not deserve a mention.
^ Little Cup evs don't work like that. Dual Screens is probably the best you'll get out of Snivy though.
