Pelipper was a Defensive wall with suckish movepool and Inconsistent switch-ins same as torkoal and vanilux, the very reason that drizzle was given to it to actually balance its uselessness outside drizzle and make way for the more pokemon who benefit from it into the higher tier (OU) from lower tier (UU). The reason we want this is to remove staleness of having to fight teams of pokemon that we already see in the competetive game we find in handheld versions. We would realize this just from the way everything is updated and fixed from time to time. Pelipper isn't op but was definitely buffed a whole lot compared to its Original versions.
