sorry dude but i was swept once by it so i thought it was a setup sweeper.You are nomming Mega Pinsir to drop as though it is supposed to 6-0 teams, which it is not; the point of a late-game sweeper is to wait until its checks and counters are weakened or removed, which is how Mega Pinsir is supposed to work. The rise in Weavile is indeed a pain, but Weavile is really frail and not that difficult to prepare for.
Not to make it a shitpost.
MMeta S rank.
Still alot of defensive pokemon,check metagross,but do not counter.With an Ice Punch it can deal with Hippo,Thunderpunch(rare but still Usable)deals a chunk of damage to skarm and slowbro,with a tough claws boosted.Zen headbutt Is there for R-wash,and some couple of other mons,presumably fighting types and meteor mash as stab.It suffers from 4mss a little bit but 4mss isnt an argument anymore,it is worst than a shitpost.It can Deal with 99.5% of the tier,barring gengar who can beat it.
