>>52725238i remember thinking of a unique ability for the fucker. One that made it resist the type-form it was and gave its unique move at the time horn leech, do that damage type grass AND the type allotted (flying press kinda deal) relating to grasses inherent weaknesses.
Spring-Bug
Summer-Fire
Fall-Flying
Winter-Ice
(poison didn't seem to fit here imo)
But it made it so not only was it a better grass pokemon for having 1 less weakness, but gaining a resistance to it, and it was easy to play around if you understood the 4 types/seasons, and giving it a flying press type move gave its unique move something to keep it unique now that it isn't unique anymore.
Winter form 4 lyfe though
