As with all modi in the world, it comes in its own physical card.  These cards can be exchanged with one another, or even combined if you're truly feeling like that.  And each has the words "fetch modus" at the top, to, of course, show you what exactly the card is and how it works.  Then the card has at the bottom the name of the modus.  Some are self-explanatory, like meowrage's, Guess, but for others, it makes no sense.  Yours is somewhere in the middle, where you can probably guess how it works.
