Demonblight

Just been having a lot of fun with this party. It's pretty expensive but there are so few cards/heroes(anti-heroes?) that it should be a matter of grinding and doing your quests to get them. Brightwing is a decent alternative for some extra survivability and it's cheaper/easier to come by in case you don't have Gul'dan as was my case. Tankwise, Kurtrus works. You could also use Scabbs if you don't have access to Diablo. With 3 legendary, an epic and 2 rare, it's expensive but a lot of fun with minimal to no set-up. Just beware anti-demon teams.
