Likewise! It's very addicting, especially once you get some decent cards. I bought the 3 expansions and spent prolly $100 on packs but now I've got the "staple" cards and have used some sites to help deck build. Got to rank 11 today!
I've been using Reno Warlock, its been working out really well. I've also been trying out a paladin and a priest deck on casual matches that tends to work pretty decently. Prolly gonna give those a shot this season and see how they do
