I'm getting it, due to how good some of the Pokemon are, despite a few being unimaginative.....

Two friends (Kinali and Detranix) and I have agreed that after we beat the game, we are to continue the building of teams, each based on the 17 types.

So far the teams we have done (in Diamond/Pearl/Platinum/Heartgold/Soulsilver) are:

Ghost

Ground

Dark

Fighting

Steel

Water

Bug

Rock

Psychic

In honor of Black and White's release, Kinali and I will be making a Fire and Electric team, respectively.

P.S. Galvantula is <3
