Usually I start the game, pick my starter, catch the generic bird, get an HM whoar, find a couple of cool Pokemon early on in the game and raise a team from that. But when I think about it, most people do that, and that's not unique in any way and it just sounds boring. So this time around, I'll be transfering some eggs over from Pearl of the team I want. These Pokemon won't be bred for IV's, Natures, or moves and won't be EV trained, they won't be that strong. They'll be Pokemon I am fond of and like really well, a team that I imagine I would love to have if Pokemon were real.
Miltank
Scyther
Eevee [For means of Leafeon]
And then I can catch a Gligar, Psyduck, and Mareep early on to complete my wanted team. =]
My team by the E4 should look like this:
Gliscor
Scizor
Ampharos
Leafeon
Golduck
Miltank
