Alright, I've updated this to include the soon to be released Caribolt, Smokomodo, and Snaelstrom! Here are their roles for now:
Caribolt: Physical wallbreaker, offensive Volt Switch pivot, Rapid Spin user, Quick Attack user, Swords Dance sweeper, Z-Celebrate sweeper.
Smokomodo: Physical/Mixed wallbreaker, Taunt-based stallbreaker, Stealth Rock setter, Defog user, Choice Scarf user, Z-Celebrate sweeper.
Snaelstrom: Mixed wall, Stealth Rock/Sticky Web setter, Rapid Spin user, Whirlpool trapper, defensive Trick Room setter.
Of course, these are just a basic overview of their abilities, and might change drastically depending on their performance after release, so keep an eye for changes during the next weeks!
Additionally, I've added a checks compendium. This addition had a long time coming, I never implemented it before because I wasn't completely sure on how to do it. Special thanks to
snake_rattler, who reminded me of this idea!
