As characters that are already being worked on prior to the ballot? I'm only saying that because Ivysaur had a really unique anti-air moveset, and I think he could be changed up quite a bit now being free from Pokemon Trainer. I realize Charizard didn't change up too drastically much to his disservice (he needs more fucking jumps damnit, he has the worst vertical recovery and no Glide to compensate, at least on Dedede level) but who knows for Ivysaur.
Wouldn't squirtle be the more popular choice? When looking at Pokemon Trainer, it made sense to have Charizard, it made sense to have Squirtle and Ivysaur was the only one left if they wanted to choose one from each of the evolutions. Ivysaur was a very odd pick to include as a player in retrospect.
