Smesibuying items related to the comp scene, like stickers and team-related skins, would be cool for the people that play comp and i'll attract quite a few people into comp.
I actually asked b4nny about this on his stream once not too long ago, about stickers or something to that tune to help fund I-series or something to that extent. To my understanding the way he put it it'll take a while of playerbase growth and comp interest before we see official support for teams in this way.
