In Scrolls, as with many card games, your cards can have pre-defined skills (such as "Haste") which offer bonus powers to your units. When some of these skills appear on cards, they are also defined on the card. (i.e "Haste: Card comes into play with a countdown of 0.")
However, while glancing at my beginner deck, I noticed that some of these cards appear to have skills without a definition. For instance, the Crossbowman has a skill called "Ranged Attacks" but what that means isn't defined.
Is there a list within or game, or some where else, explaining what these skills are and what they do?
