From the FFG website:
Star Wars®: Edge of the Empire™ Specialization Decks, available through Print on Demand, provide GMs and players with a fun and easy way to manage character and NPC talents at the gaming table. New and experienced players alike will appreciate these handy reference cards, and GMs will love being able to keep the action moving. You’ll have the text of your talents at your fingertips, leaving you free to focus on the challenges at hand, while art for each talent immerses you even further into the Star Wars universe.
Marauders prefer to get mixed up in a melee, weapons in hand, smashing and slashing their way through their foes. The Marauder Specialization Deck keeps the text of your talents in front of you so that you can free up your hands for more important business!
Each Specialization Deck contains:
2 cover cards (including a reference guide for each deck)
20 standard sized talent cards
