>>36705389Meganium is a slow (by today's standards) defensive grass type with its bulk distributed in such a way that it doesn't synergize with its typing at all, unlike tangrowth, besides barely having moves it could support its team with, and a subpar ability that only works under a weather that boosts one of its worst weaknesses.
Aurorus is a slow defensive ice type with literally the worst defensive type combo in the entire game, which while still decent offensively, fails due to its low speed and average SpA by today's standards. Its refrigerate set is not threatening enough, its snow warning set has no aurora veil, all it can realistically hope to do is set rocks and die.
Bananus is yet another slow defensive grass type but with the twist that it has an insta-finishing ice weakness and takes increased damage from rocks, in exchange for an immunity to a type it would resist anyways. Harvest is nice but realistically worthless since there are better abusers for it. I think it learns defog so that's good, however I can't be bothered to check if it actually does so in case it doesn't then it's even worse than I thought.
