also another question,
i'm finding it difficult to save up 35 gems to max out a training field. i always get to around 5 from videos/quests and somehow accidentally use them (ie, losing a double down, tapping too fast and wasting a gem on 'keep double down'). is there any way you guys recommend for getting and saving gems? im currently ranked slightly below 1000 in the arena and around 8000 for epic boss dmg.
