stickers

In SSE mode, you need to select Sickers from the menu. Then you have each character (displayed in the bottom-right) and their Trophy Stand (in the middle) Select from stickers you have and put them on the stand. But only one stat up works for each stand. I.e. Use an (leg) up and you can't use any more leg ups on te stand and still have them effect it. Itll still take up space but be useless.

You go to the Sticker Menu on Subspace Emissary and it displays a area for stickers. Whatever stickers you place on your character will give them a boost in power or an item. Only use one power up per character. So if you use a Flame up on one character,you can't use another one with Flame up. It will be useless and it will take up space. One more thing. If you equipped stickers on a character,don't take the sticker off. If you do,it will be gone forever until you find another one.
Hope this helps.

Use them in the SSE,you can apply a certain amount if there is
No more space left to add some.

There are different stickers with different effects that will
Help you make your character stronger.

Well when you are in SSE mode select the stickers that meet the requirements.not all stickers will work for everyone,some are exclusive actually most of them are <_<

If you look for stickers, you only find them useful in subspace emmissary cause it's the only way to use the effects.No effects on the Classic, All star, group brawl, special brawl, traning, events, tourney, rotation, home run contest,multiman brawl,target smash, or subspace bosses.Hope I helped!

Where it says back to map, bottom left corner next to your p1 thingy , it says sticker.
