Snorlax is a beast, It takes care of everything except levitating ghost types, which the rest of my team deals with. I'm pretty sure I've used it for every singles battle since its been on my team. Snorlax and Camerupt wrecked the Elite-4. Shoutout to Carbink for making all this possible with that Trick Room.
