Actually, it was DBsummit who turned me on to Dugtrio.
I still think it's slightly cheap, with Arena Trap... but once you know someone's using it, it becomes easier to kill. That's why I'm debating whether to keep Claydol, or go with Duggie.
Claydol serves as a member of my walls, with him my team walls every attack thrown at it. But with Dugtrio, I can kill most, if not all, of the SkarmBliss killers out there (including ThunderPunch Metagross and Electivire). It's already known that I use SkarmBliss, so anyone who throws in a Magnezone, Tyraniboah (never see those anymore, though), or even McIceGar, has a great shot against me.
