TL;DR I juggled my pokemon and snarl'd at you until you couldn't hit things hard.

Mega-Manectric and Staraptor both have Intimidate and a switch-out damage move. Using them I could for free half the enemy's ATK stat and then switch to my proper tanks. Saltshaker (my umbreon) had a similar purpose, Snarl did damage to both enemies as well as lowered SPA. Other than that she sat there, relied on her phat booty to tank everything, confused their guys, and Heal Bell. Saltshaker earned her name due to regularly causing rage quits.

Klefki was actually a monster. With Prankster gave Switcheroo/Toxic/Thunder Wave +1 priority, which is great and made it's Lagging Tail (holder moves last in it's priority bracket) moot. With Lagging tail going through Tailwind and Trickroom, and Klefki being surprisingly tanky, many angers were made. Many pokemon also rely on their items heavily, so being able to switch them allowed Klefki to counter a lot of strategies.

To make things more confusing, generally people specialize their tanks to counter either Physical or Special. I don't. This made things even more fun for me.
