I love that Lileep and Cradily are in the lead. They're so amazing, but have pretty poor movepools. I would like fossils to have like a "natural" form, where rock is replaced by a second elemental type.
E.g. Natural Lileep Water/Grass
It would be nice to have Almaldo as a Water/Bug, Surskit needs some company.
