Banette is a creepy design with a surprisingly useful ability setup, and Mega Banette gets Prankster for priority Will-O-Wisp and Destiny Bond. Is Banette worth a team slot, or is it still too fragile?

Manectric is one of the faster Electric types, and Mega Manectric keeps Intimidate, which is great for support. Does Manectric still hold a place on teams, or have newer Electric types taken over?

Walrein has solid bulk and the Ice/Water typing has fewer weaknesses than pure Ice. Is Walrein actually a decent defensive pick, or does it get outclassed by other Water and Ice types?

Seviper gets overshadowed by Zangoose, but it has a solid Special Attack and a decent movepool. Does Seviper have any real competitive niche, or is it mostly a Hoenn nostalgia pick?
