Pokémon X and Pokémon Y

Most typical strategy is hit and run, use an attack and then switch it out.
I find that so damn boring.

Also neither worry seed nor simple beam work on pokémon with truant.

you find it boring, but it's great for mindgames, especially with spikes and stuff around, heck, you don't even need to attack with the slaking, just switch him in, and switch to the counter of whatever the opponent is going to switch in.
