Pokémon!

Hello! I found this community this morning while waiting for my coffee to brew :)

I'm aware that Pokemon Yellow hasn't been new for ten years (if you're in North America) or eleven (if you're in Japan), but I've been replaying it recently and have a question about a good team to go through the game with (assuming that I can't trade with anybody, as I don't expect to be).

I'm keeping Pikachu and a Graveler for sentimental reasons (Pikachu being my starter, the Graveler, while still a Geodude, being crucial to defeating Jessie & James the first time they showed up), so that covers flying, water, poison, fire, bug, and electric types. I probably want a psychic type, and an empty space for the Pokemon who knows whatever HM is needed at the moment, but that leaves two blank spots!
