Wizards of the Coast has announced that starting with the Magic 2015 Core Set, new Clash Packs will alternate with Event Decks. Each Clash Pack contains a pair of 60-card decks designed to be played against each other, including six alternate-art foils. A strategy insert included with each Clash Pack shows how to pool the cards to create a new deck on par with an Event Deck.
