Slowking's always been a Pokémon that is associated with Trick Room, and for good reason. Boasting a respectable base 100 Special Attack stat, as well as 110 Special Defense, Slowking can come in on many special attackers that rely on their speed to dominate, and set up the Trick Room. Adding to its usefulness is the amazing ability: Regenerator, allowing it to set up, and switch away to something more appropriate if need be, regaining 33% of its health in the process.
Naturally, being a Trick Room Pokémon, Trick room is a necessary move. Scald for Stab and burn due to Slowking's Defense being a bit lower than his Special Defense, Fire Blast for trolling, as the likes of Ferrothorn and other grass types like coming in and trying force a switch or kill it outright, only to be destroyed by fire blast, which nobody remembers it even has due to it being a water type. Nasty Plot only makes Slowking scarier, hitting an amazing 656 Special Attack after just one.
As for the item, Lum berry is my personal preference to keep it from being hit by Toxic, and increasing its longevity in the long run, as well as causing the opponent to waste a turn trying to status it in the first place. Naturally Leftovers is a fine choice, as well as Life orb if you're feeling especially bold, which synergises well with Regenerator.
