These cards are only obtainable through an enemy's Mines Artifact. They will activate the moment they are drawn, dealing damage to you (and your monsters in some cases). You will then draw a new card.
There is no way to avoid these, Even when milling them as Turbo Effects activate even when the Card is milled.
The mines are usually harmless but can be very dangerous if it is drawn on later rounds.
- If you obtain these in your hand without drawing them with the help of cards like Investment, they do nothing aside from making you lose gold (similar to using Multi Shot outside Justice).
- These cards existed before Beta 21.0 when the Turbo ability was introduced, so they gained a description change because of it.
