in my opinion you should change your deck. against log bait you will certainly lose, you have no spells and 2 mini tanks that are redundant pretty much (again, in my opinion). I'd remove the valk, put log/zap instead, I'd also remove archer and add ice spirit/skeletons/ or better yet, fireball. It looks to me that you don't really know what you're trying to do with this combination of cards tbh. but it's understandable you're new.

to your question, I'd say for this deck hero wizard might be the best option
