"I'm very proud of this cake that I made. Enjoy ♡" ―Mio
Mio's Christmas Cake is a unique Boost card that cannot be drawn from the deck, and can only be generated through the use of the 
Christmas Inferno card.
Effect[ | ]
When used, the player will be prompted to target any non-KO'd unit. This can also target the player. This card has varying effects depending on which player is targeted.
- If the player targets themself, the player will gain 1 HP.
- If the player targets any other unit, the target will heal up to 2 HP. Then, the player will heal HP equal to the amount healed by the target.
Notes[ | ]
- When Mio's Christmas Cake is discarded or used, it is removed from the game rather than being sent to the discard pile.
- In the Overindulgence Chaos Mutator, Mio's Christmas Cake cards that are drawn from the deck are not removed from the game, and are sent to the discard pile as normal.
- Mio's Christmas Cake counts as a Sweets type card.
- If the player targets another unit, and that unit cannot heal (whether due to having full HP or higher, or playing as ), the player also does not heal from this card's effect.
