I think it’s best to keep the final one an elimination like the other rounds. With threads like these, I for one am not reading the OP post every time a new poll-thread is posted (sorry OP), so if every thread is an elimination, and the final one is the opposite of that, I think it will only confuse the potential voters.
Unlike the Grass-Type polls for which I had a completely different elimination order, this time the elimination is mostly how I would eliminate them myself, except for some minor differences. My order would have been: Scorbunny < Tepig < Fuecoco < Chimchar < Litten < Fennekin < Charmander < Cyndaquil < Torchic.
