Played about 8 hours straight today when it launched. Crunching down my phone battery like nobody business, a 10 minutes game easily down battery by 8 to 10%. And i was running low spec graphic. I can't find the setting for the darn cards graphic, wish to tune it higher because i cant read or see (have to guess) my cards on hands. Opponent's card flashed too fast when casting spell, and next thing i know i down a follower (minion in game). Limit 5 cards on floor, look stupid. Evolve and super evolve concept good but killed the game.
