unown is basically just a spacer.
terrible stats and only a hidden power spammer.
snorlax on the other hand (love ya bae <3) can handle anti-defense special wallbreakers with it's decent sp. def and can also take care of dark/ghost types with the high base attack stat it runs, and crunch being in it's movepool, or as an alternative, pursuit, doubling the 40 power and +7 priority on a switch-out. it can take an amnesia, but that wastes a move slot, since it's sp. def is already so high. so it would most likely be complimented with body slam, with the 30% par. effect. it would be better off with return, for that STAB and higher power due to the happiness levels being so high. this of course loses the paralysis, but has a higher chance of a knockout. lastly, earthquake is a nice extra coverage for poison types such as gengar, with it's levitate ability out of the park (rip levitate gengar ;-;), it can easily set up a kill on gengars with earthquake. of course, this set is a gen 5 underused (UU) set, but fuck it.
