Finished LoE on Heroic. Of the 13 missions I think only 3 were heavily rng dependent, those that were, were pretty frustrating. The one where the opponents hero power was basically evolve was kind of funny though. My big ass Chtun just stayed as cthun after the hero power.
Cthun was fun against the guy that only takes 1 damage at a time too. Went to fatigue and it took 3 cthuns +me attacking face with two of them at the end but I was able to pull it off relatively easily.
The guy that starts with a 2/3 and a 3/5 on board first turn and messes with your card cost was definitely the hardest.
Very happy with the card back, I always thought it looked great.
