What do the pieces of paper do in super smash bros wii?
They are stickers. If you are unsure of what they are decals, stickers are sort of like Smash bros melee trophies and fight. However, there is a label much more than trophies (Due to the fact that they appear in fighting games) and because of this, they are able to show a lot of interesting characters who were not able to get their own trophies. In addition, the Subspace Emissary, which can be applied to stand a character trophies to boost statistics, such as fire resistance, trophies support sink rate, dropout rate sticker (The paper thingys) and so on. Hope this helped and enjoy!
