Mushroom cards can be either Boost or Battle cards, making 20 total variations of cards (10 colors and 2 types).
Before the game starts, each of the 10 colors of mushroom card is randomly assigned a type, with 5 being Boost cards and the other 5 being Battle cards. They are then each randomly assigned a mushroom card effect, out of a list of 13 possible Boost effects and 11 possible Battle effects. Finally, all effects with more than one possible value will be randomly assigned a value. For the duration of the game, any given color of mushroom card will consistently have the same card type and effect that was randomly assigned to that color at the start of the game.
Although each mushroom's effect is determined at the start of the game, these effects are initially hidden to the player. All mushroom cards, when first obtained, will have their effect description listed as "Smells funky.", obfuscating their actual effect. Once a mushroom card is used once, the description of that color of mushroom card will be changed to reveal its true effect, with all new mushrooms of that same color now bearing the revised description. In Normal Mode, the description is only changed for the player who used it, while in Co-op Mode, the description is changed for all players.
There are 24 possible base mushroom card effects, with 13 being Boost cards and 11 being Battle cards. Many of these effects can additionally have 3 or 5 possible values, bringing the total amount of effects to 60.

- When a Mushroom card is used or discarded, it is removed from the game rather than being sent to the discard pile.
- The "Lose HP" Boost Mushroom card can cause KO, unlike most "lose HP" effects.
- If the "Take damage" Battle Mushroom card causes the player to be KO'd, it counts as a win for the opponent.
Although a mushroom card's description is only revealed to the player who used it, observant players are still able to determine the effects by paying attention to the opponent's stats, total health, and the sound effects produced by the card.
