Snarl lowers special attack making special attackers less useful against it. Anything without Focus Blast can't put a dent in Furfrou fast enough. I usually switch after two snarls to something that can set up.
Slowbro Scald Ice Beam Slack Off Disable

Cincinno @Focus Sash Skill Link Encore Knock Off Bullet Seed Flail
If the opponent is slower than me and doesn't have a priority attack I knock off it's item and flail the next turn if it hit me hard enough to break the sash. Flail has 300 base power after stab which puts a dent in anything. Bullet Seed is for fragile ground or water types. Encore prevents setting up. As long as it isn't agility or Speed Boost.
