Platinum Bertha also has three with a quad weakness to Grass-Type, however she packs significantly better type variety with Golem having Fire Punch and Rhyperior having Avalanche & Megahorn for Grass-Types, in addition Gliscor takes neutral damage from Grass-Types to help balance things. much like how Whiscash serves as a counterbalance against Water-Types as well as the Electric-Type moves on Gliscor and Golem.
Personally I think they should've swapped her Golem with something else though, since two Rock/Ground Pokemon is still a pretty major weak point for Pt Bertha. Torterra, Steelix or Mamoswine would work well, Torterra to further counter Grass and Water-Types although does open up her team to Ice-Types more, Steelix is good for Grass-Type and Ice-Type and since Flint isn't using one anymore in Platinum and Mamoswine also works for dealing with Grass-Types and Ice-Types, it's hard to say what would fit Bertha best out of those three for her character, I would lean towards Torterra or Mamoswine with the latter being better for team balance.
