What are your steps to picking types/type coverage for your team? I'm kind of wanting to get into competitive play/pokemon showdown but I don't really know how incorporate the type chart into my team in a smart way. Is it just simply, pick one pokemon, then pick the second based on a type that can defend against types that are effective against your first pokemon, and repeat till you have six? What do you do? And how do you handle dual-types?

Also, if you don't approach building a team based on types, how do you factor in types? Thanks.
