not quite too old for this, apparently
Usage of Thunderbolt on Haunter: 36.677%A significant number of Haunter carries T-Bolt and a significant number of Scolipede carries Bug Gem or Life Orb, which means you cannot set up. Some Scolipede also have three attacks, which is most likely EdgeQuake, and LO EQ from Scoli also deals a number to Carracosta.
Usage of Bug Gem on Scolipede: 2.134%
Usage of Life Orb on Scolipede: 18.257%
Admittedly EQ is used more than 50% on Scolipede, and Rock Slide is almost 50%, but you get the picture. This is all I'm going to argue about Carracosta, as I've said all I needed to and the people running this thread all agree Carracosta is S-rank.
Anyway, I pushed for Seismitoad to be S-rank when this thread was being crafted. The fact that it has a huge amount of versatility makes it by far the best "catch-all" Pokemon in the tier. It has like 4 "main" sets, and another handful that are more team specific but still very useful. If you need a Rain Sweeper, Seismitoad can outspeed opposing Ludicolo and hit hard with Sludge Wave. If you need a check to opposing Carracosta and Physical Samurott, Physically Defensive Seismitoad can set up SR and check them. If you need a Jynx check, Specially Defensive with Earthquake. If you need a lure for Tangela and Alomomola, SubToxic is there. Heck, even Sub Endeavor is a good set. This versatility, combined with great typing and great abilities is what I believe pushes Seismitoad over the edge (plus I think it's darn cute).
