Instructions
Collect stickers during multiplayer fights, which are referred to as "brawls." They will appear randomly during the fights. Pick them up as soon as you see them.
Defeat enemies in the main mode of the game, the "Subspace Emissary." Enemies will drop stickers at random.
Enter "Spectator Mode" and place a bet on the fighter you think will win. If you are correct, there is a chance you will receive a sticker.
Play the "Coin Launcher" mini-game to receive more stickers.
Enter the "Home-Run Contest" and hit the sandbag as many times as possible. The sandbag will drop stickers at random.
Enter "Trophy Mode" once you get the Fierce Deity Link sticker. Select the trophy of Link, Toon Link, Ganondorf or Zelda. Select "Stickers" and place the Fierce Deity Link sticker on the base of the trophy to receive an increase in attack for that character in the "Subspace Emissary" mode.
