Is this the worst possible reward from the daily quest?
I can win this from 2 battles I'd rather have the potions for a chance to get higher value cards and each the next tier sooner.
I'm still starting out so I only get 1 chest per day. I'm assuming that once I earn more cards and can get to a higher rank that my daily reward will contain more chests.
There should be a potion or items that allows you to reroll chest rewards at low levels
