Guys, I need a sixth pokemon for my Trick Room team. I'm thinking some sort of status inflictor or wall, preferably a second Trick Roomer, since my team depends on it being available. Any other critiques welcome, I'm pretty new to the whole competitive battling thing. Although I intend to keep Ampharos and Marrowak, the idea is to build at least a half-decent team that can use them effectively.
