A slight wording suggestion: abilities are actually called skills, and there are two types: active and passive. Right now weapons only have one type of skill, active, and creatures have up to one active and two passive skills. Active is always the text under the icon, while passive is obviously the text under "passive skill". If you make the wording consistent under the Creatures & Permanents section like this, new players will have a firmer grasp of creature and permanent mechanics.
