I think it's great! I like how user-friendly it is for people who have never played a hardcore card game like Magic or a table-top RPG like D&D, the terms are all explained and I get a good feeling about the tone of the text, explanatory but fun and not obnoxious. You're catering to a large range of target audiences, ages and genders, and I think you've nailed it. Good luck for the rest of the rulebook-making, your project is awesome!!!!!
