New to the game. While reading what the cards do, it's sometimes confusing understanding the description. This will definitely be a problem for younger kids playing. It seems like they were written quickly and as terse as possible. For example "May Self Target", why so few words? At first me and my friends were trying to understand exactly what that meant until we realized it's saying "You may target yourself with this spell". At first I thought it meant there was a randomness to it where you may accidentally cast it on your self instead of the target you picked. Stupid I know, but that's just one example. The Block explanations for cards like "Add 3 to block rolls..." took a few minutes to understand as well. You don't need to explain in as little words as possible for a new game like this. Go ahead and make the descriptions clear very clear, instead of very concise. There is limited space, but there was still plenty of room to fit more words.
Depends. Have you noticed that many of these things are keywords, and as such give you little "tooltips" with more information? Likewise, as Gary said right at the start of the level 1 tutorials, you can hover over anything (like Block numbers) to understand how they work. So . . . have you seen all these, and still feel it could use improvement? If so, go right ahead and type up suggestions. The devs listen!
