Note: The cardlist shows a card with the name Nightmare Fuel. The card was renamed Blood Transfusion, but the cardlist was not updated. You have the correct cards, though.

Game description from the publisher:

Adventure Time Card Wars is the most epic card game ever found in the Land of Ooo, or anywhere for that matter! In the Adventure Time episode "Card Wars", Jake begs Finn to play his favorite trading card game. Finn accepts, despite warnings from Beemo on how very competitive Jake can be while playing the game. Finn and Jake battle against each other to decide who will be the Dweeb and who will be the Cool Guy.

Now fans can play the actual Card Wars game in Adventure Time Card Wars: Ice King vs. Marceline, with all of the action taking place in four combat lanes.

Each turn, a player has two Action Points to spend on Creatures, Spells, and Locations, and cards cost between 0 and 2 Action Points to play. When you summon a Creature, you choose which lane you want to place it in; some Creatures have FLOOP abilities that allow you to use their special abilities. When you attack with a Creature down a lane, you might find an opposing Creature, or you might get to deal your damage straight to your opponent's Hit Points. Reduce your opponent's Hit Points from 25 to 0 and you're the Cool Guy (and you win the game)!

In Adventure Time Card Wars: Ice King vs. Marceline, which contains all new cards other than a few rainbow card repeats, the Ice King and his IcyLands deck take on Marceline's dark and crafty Useless Swamps & NiceLands deck. IcyLands creatures are all about attacking directly. They would prefer to avoid attacking other creatures. One way they can find some clear lanes to attack down is through frozen tokens. Through various means, these chilling tokens can be placed onto your opponent's Landscapes. Opponents will find playing creatures onto frozen landscapes rather difficult. Where the Ice King finds an opening, he will strike as hard as a blizzard!

Marceline's deck is a Useless Swamps & NiceLands deck. This is the first time that NiceLands has been paired with another landscape type, and the chemistry is going to burn hot! The Useless Swamp side of the deck is themed around denial, discard, and dirty tricks. Some of the Useless Swamp Creatures are willing victims to your dark tidings. When they go, they leave a lot of destruction in their wake. The NiceLands side of the deck is themed around creatures with exactly five damage on them. This is a tweak to the NiceLands strategy as seen in the original NiceLands deck. There, the creatures thrived with various different amounts of damage on them. Now the trick is to get as many of your creatures as you can to have exactly five damage on them. When that happens, look out!

Each Card Wars starter set has a pair of different forty-card decks and is ready to play right out of the box. Mix the decks together to come up with your own righteous combos!
