You're most likely making your team with a variety of types; one grass, one water, one fire, one electric, etc. Competitive team building expands on that by making your consider the roles each Pokemon will play on your team (sweeper, wall, phazer, etc.). Everything is just a little more in-depth.
A lot of people here will hate on Smogon, but it's actually a pretty useful place for seeing good movesets laid out in one place. Figuring out complicated EVs yourself can get annoying, so it's nice to have them laid out already.
