Forgot to add this to my post: if you're going to be running sticky web and stealth rock, having defog on mandibuzz is a horrible idea. Then something like Bisharp can switch in, net a possible +4 attack thanks to defiant, and proceed to bury your team with sucker punch and iron head. Whirlwind and toxic are better, as the former allows you to stop things like SD terrakion whereas the latter allows you to beat things like hydreigon and togekiss one on one without being forced to rely on a different pkmn.
