@Nicecoolguy0 The Grand Smoker is not real hard. I beat him without paying money. You just have to know the right line-up, use potions such as softie and poison. If you can't beat him just grind easier floors with chests. Make sure your gear is the best you can get (If you need more rubies then grind the Grand Gatekeeper).
Idea for the uncommon card in a tourney: It rewards a uncommon card from that set i.e., blight tournament rewards blight card like a Flesheater or Blight Golem.
@Prival yeah something like that happened to me, I upgraded communications to lvl 7 and connection failed. I didn't complain I just won some more stuff to get credits back.
Something that would be nice if it were added is that when you won a mission it rewarded stamina and when you won a faction battle you got energy. Just a suggestion for longer intervals of play time.
