As everyone already know, Fionna and Cake are the lovable, cute and alternate-reality female versions of our heroes, Finn and Jake! Their decks take us back to where it all started — The clic "Cornfields vs Blue Plains". But these decks are all new and full of surprises! Fionna's Blue Plains deck is actually part Rainbow, allowing for maximum customization. Several of her Blue Plains cards work rather well when paired up with Rainbow cards. The Blue Plains "mastery of card drawing effects" gets a new twist, as well. When Fionna gets her hands on a sword (or two or three), watch out! Cake's Cornfield deck is centered around Buildings. The more the merrier! In fact, this deck has more Buildings than any previous Collector's Pack. And if you play your cards right (literally), you can get more than four of them into play at once!
