Lonewolf is going to be a problematic card because you will have to be Rogue at the very beginning of your turn before there is a fast action to switch over. Same for any fast events, you have to be that class before you can use them. Ward of Protection is probably fine because you will be Mystic most of the time. Eureka! and Deduction may be a decent add since you will probably be Seeker if you are investigating. But, even they become dead draws if you are Rite of Seeking. maybe think Mystic for fighting and Seeker for investigating and Survivor to fill in the gaps.
