*Dunsparce (Shedinja-treatment, but not genderless)
There's a reason why Shedinja is genderless you know...
*Emolga (Porygon-treatment, but this will make Sentret useless)
What has Emolga getting an evolution got to do with Sentret...?
*Pansage, Pansear, Panpour (Tyrogue-treatment, but evolves via stones)
I dunno, they already evolve with stones as it is, if they were to receive a pre-evolution I think they should evolve with happiness instead. (Not that they need pre-evos imo.)
