Feferi: Go fish.

Your GO FISH MODUS requires another sylladex user to function.

You ask that person if they have any of that card. If they do, they give it to you and you captchalogue it. If they don't have the card in question, they rummage through THE POOL for a card, any card.

In years coming, thanks to the efforts of our heroes to captchalogue anything and everything from human culture they can find, THE POOL will overflow, expanding into an endless sea of sylladex cards, packed with thousands of years of human and troll history. You will never want for any old shit.

For the moment, it is EMPTY.
