Unwrap all of the cards. Large cards with the Violet Sinister Bunny on the back are shuffled into your Draw Pile that should already contain Blue, Yellow, and Red cards. Add the four new Carrots to the 16 already for sale at Kaballa’s Market. The small Cabbage, Water, Carrot, and Defense Cards are shuffled into their respective piles.
All Booster Decks are compatible with the Blue Starter Deck. However, Killer Bunnies plays best when the Booster Decks are added in sequential order which can be found in the instruction booklet below. If you do play with non-sequential Booster Decks and a card is drawn during play that refers to another card that does not exist in your Killer Bunnies deck, then a player may discard it and draw a new card.
