Well yeah, Pokemon Pearl is quite an interesting game in the Pokemon Series. However, everyone can have different options in terms of the starters available. Since you asked me, this would be my ideal team for PEARL:
-Infernape (Chimchar as starter)
Good stats, and blaze. A skillful attacker for you team to go head on!
-Shuckle (Your wall pokemon)
Shuckle, with it's haxy Defense, and manipulation of Power Trick and Trick Room are an awesome combo. Almost / deadly / !
Gallade (Physical Attacker)
Calm Mind and Stored Power spam will knock your enemies out!
Luxray (Sweeper)
Luxray with it's static inflicting moves and chances of paralysis. Accompanied with backhair standing movepool, it's a good option.
Blissey (Nurse)
Blissey will server as a nurse, rejuvenating all your pokemon amidst battles!
Thanks,
