Hah, there was a battle I saw on Youtube: guy with a leading Ninjask against someone who led with a Slaking. The guy had his Ninjask Protect on Slaking's active turns, and boost Attack on the loafing ones. XP Poor Slaking guy just didn't know how to use him well enough. Ninjask ended up Passing +6 Attack and Speed to a Breloom, who proceeded to sweep the entire team.
I dunno, though. I can't get comfortable with Shoddy myself. It's a little too mechanical and impersonal for me. Bah. I could probably use the practice against toughened players, though. How do you fare in battle?
