Hey guys. I looked through the catalog and couldn't find a thread that would help me at the moment. I'm pretty okay at competitive battling, but I'm shit at actually building teams to make them work together. I know the basics, like having three core Pokemon, a sweeper, and some support, but I don't know which Pokemon go where since each can have different builds.

Ideally, I'd like to run a baton pass/speed boost Scolipede, along with Mega Mawile, and a wish-passing Eeveelution [preferably Umbreon, but I'll go with Sylveon/Vaporeon if anything]. However, I don't know who else to run.

Other Pokemon I'd love to have are Togekiss, Dragonite, and perhaps Skarmory, but I'd already be setting up spikes/toxic spikes with Scolipede and I don't know if there's a need for him anymore.

Can anyone help me here?
Also, team-building general, I guess.
