Drop the unstables. Harrison is a tech choice that some like and others don't. I honestly haven't liked it too much. Harisson is strong vs: Rogue, paladin, hunter, warrior. You already counter rogue and patron warrior, you are strong vs face hunter (though not midrange or hybrid hunter) And warrior seems to do decently well vs paladin. So eseentially harrison is helping more matchups where you are already strong than not, and vs hunter he is often just too slow anyway. Adding in ysera or rag adds a lot of late game strength. Other than that, 2nd brawl can be very good, it is very strong vs patron and zoo decks which currentlly are very strong. Owl can be good to have 1 silence, also you can add cards like 1-2 senjins to help vs all the faster decks that are out there currently, or a revenge to also help vs faster decks and be a possible comeback board clear mechanic.
