I feel Cofagrigus should be on that list for the same reasons that Snorlax is on it, as it walls the other half of the attacking spectrum with ease. It's arguably the best switch-in to any physical attacker, minus CB or LO Darmanitan, and can pack an offensive punch through Trick Room and Nastly Plot, similar to how Snorlax can use CB or Curse (even though nobody uses that anymore). Cofagrigus is also another one of those solid answers to the plethora of Rain Teams that have been popping up like mad thanks to the new additions.
