Card Hero (カードヒーロー) is one of 18-Volt's microgames in the Japanese version of WarioWare: D.I.Y. Showcase. It is based on the Game Boy Color game Trade & Battle: Card Hero. In localized versions of WarioWare: D.I.Y. Showcase, it was replaced by the microgame Punch-Out!!, which features completely different gameplay.
The player must cut open the packet to obtain the card inside without cutting the card as well. Each pair of scissors will be highlighted one at a time and pressing the OK button will stop it on the currently highlighted pair of scissors. In order to win the microgame, the player must press OK while the top pair of scissors is highlighted. If the middle or bottom pair are highlighted instead, it will cut both the packet open and the card in half, causing the player to lose.
