SS OU First true attempt at a SS OU team

[realcourage]

Hey all, I'm pretty new to team building and all of that, but I feel like this team (with much tweaking) might be okay. Not good, but okay. I've been toying with a few things, namely putting in ttar, because poltergeist was forcing a sacrifice every time an alolan marowak came out. Suggestions would be warmly welcomed, as I am very much so a noob. (team started as a way to test new moves btw) My only mons that I don't want changed are Rillaboom and Clawitzer

I'm locking your RMT for the time being as the forum rules require that you provide at least 3 lines of descriptions for each Pokemon to explain their roles. Please read the rules carefully and take a look at Team Showcase to see the level of detail we require. PM me with updated descriptions and I'll be happy to unlock this.
