Threw together my first Gen VI team on Showdown. It's not very good, but I'm still doing somewhat well with it, I guess.
Carbink and Swalot aren't very useful, but I feel like they'd be way more useful for a different team. Swalot spreads sleep and buys free turns, which is great for set up sweepers and such. Carbink...my Carbink mostly just puts up rocks and dies, sadly. I'm probably not using the poor fairy to its full potential. Toxic/Stealth Rock/Protect/Power Gem is a pretty meh moveset for it I think, especially since poison interferes with Sableye's burns and Swalot's sleep.
