please need help rating my pkmn team HS!?

k im about to go for the elite four but i need a rating on my team?

1. typlosion ( starter)
2. swampert ( migrated from ruby)
3. ursaring ( traded on gts for my ho-oh)
4. rhypherior( traded from platinum)
5. zapdos ( caught)
6. groudon (migrated from ruby)

im thinking of getting a phycic or gost type in there but the team has strong defence and offence. my typlosion is jolly so it outspeeds alot of pkmn. im not realy worried on stats and evs i just care about typing for now. stats can be altered thorugh the lvling

:/

Swampert is in my team, and tyranitar. Where one will fail, the other shall succeed.
