Hiya Mochi ^^, I can help u with team building. Its pretty much my specialty since i have been helping people with that for years. It isnt that hard when you think of it from the basics, also check out the pkm marriland team builder as it shows weaknesses and resistances of your team, then just find movesets and spreads on smogon. Once you get the idea, you can be a pkm master with the most basic pokemon. As long as they compliment each other ^^
