Castform 5th gen, the entire thing is great, but the third paragraph alone is fantastic:

4th Gen Kakuna for this line:
This is your standard Choice sweeper. With Bug Bite, Kakuna is not walled by the likes of Steelix and Steel-type Arceus. As a matter of fact, Bug Bite's addition lowers max HP / max Def Steelix from a 94HKO to a 36HKO. Max HP Steel-type Arceus is now a 25HKO, while min HP/Def Psychic Arceus is a 22HKO.
