I did a bit of pseudo-reasoning and determined that Furfrou probably has decent potential as a wall, solely because normal types only have one type weakness, fighting, that mainly hits with physical damage, and all Furfrous have Fur Coat, which reduces all physical damage by half, which means fighting type moves don't have double damage unless they're special, which is only a few of them and are rarely used to begin with. Combined with an above average sp. def., and Furfrou can be surprisingly hard to kill.
But mainly, it's because I want a Dandy Trim Shiny Furfrou named M. Baguette that knows Substitute and Toxic, because #yolo
