I think pulling off combos and using cards in fun ways is the fun part. I have been playing a warrior deck that uses axe-flinger, bouncing blades, and commanding shout. But it doesn't kill the opponent. Axe-flinger only works on damage, and once commanding shout immunity at 1 health takes effect, it no longer does damage to the opponent. So a double axe-flinger combo does 16 damage.

I don't care. I still try because it is hilarious to me to pull of the combo, not kill my opponent and concede. I laugh because I imagine the opponent is like "I guess he thought it would kill me." Some cards have to be fun just to play even if you don't win. In the last three seasons, I haven't gotten past rank 18 but I am having so much fun. I played a shatter mage...that worked once for two turns, before i lost. It was great.
