Snorlax @ Leftovers
Trait: Thick Fat
EVs: 80 HP / 176 Atk / 96 Def / 156 SpD
Adamant Nature
> Curse
> Body Slam
> Crunch
> Selfdestruct
Nothing out of the ordinary, really. Standard EVs for offensive CurseLax, but with Selfdestruct instead of Earthquake. When I was trying different things to mention on Snorlax's analysis, I really liked this one for offensive teams. +1 SD wrecks bulky Water-types that try to phaze Lax away, at +1 Body Slam+ Selfdestruct 2HKOes Gligar 30% of the time after SR (that is, if you get the para, otherwise keep trying), and you can also leave Rhyperior impaired after a couple of switches (Selfdestruct does around the same amount of damage to Rhype than Earthquake!); everything above makes Scarf Darmanitan a good partner for this. Another good one is SubPass Shao, if you can pass a Sub to Snorlax it can actually use defensive Cofagrigus as setup bait (or if that thing has Haze, just Crunch it until it faints). This thing works even better with Spikes support, obviously.
