Lets see what you got without the three I mentioned.
Level 62 Torterra
Level 60 Staraptor
Level 60 Rapidash
Not too bad a start. 5 types covered so far.
I shall piggyback off and suggest Electivire. As he and B~T have said, Electivire sounds like a great Physical Sweeper. If you can't get him, then aim for a Volt Tackle Raichu like me. =P
Attempt to get the other two starters. Infernape is a better choice than Rapidash, IMO, with a more varied moveset and whatnot. Empoleon is useful due to the Steel sub-type and it's advantages.
As for the last one, well, I can't think of good suggestions ATM.
