What I mean is what is a good base type settup for a team? Mine currently is Fire, Water, Grass, Rock/Steel, Electric, Dragon, and ghost/dark.
You want synergy. That means that if one Pokemo is weak to a certain type, other Pokemon can switch in and resist.
Ex: Scizor and Rotom-W. Scizor is weak to Fire, Rotom-W resists Fire. Rotom-W is weak to Grass, Scizor resists Grass.
