Mushroom is a card that was created through the effect of Shigeru Miyamoto by MasterBlade. It depicts a Mario style mushroom.
Mushroom doesn't have any hearts or attack. It is equiped to a card and that card has its hearts and attack doubled until it is attacked, working much like its videogame counterpart.
- Mushrooms count as drugs.
- MasterBlade used defense instead of hearts, despite CYOGTCG cards not having a defense stat.
