I don't care what anyone says, I couldn't be happier about this inclusion. Not only did one of my top five most wanted characters get added and end up being good, they're also a rushdown, which is my favorite fighting game character playstyle. Isabelle, Sephiroth and Steve were all cool additions, but this was the announcement I really popped off at.
Given that the bar of the Nintendo picks for the DLC packs was already pretty low, these two are easily the best out of the 3 Nintendo slots in the two DLC. They're basically two characters in one and while I also haven't played them a bunch, I remember having a pretty fun time playing them when I did.
