Great content as always!
You missed the chest that had 1482 in it and there is another "Dice" style mini set but I forget what it's called at the moment. =P
Also I think you can save your season reward chest and not open them right away, which could buy you time until the new reward cards are eventually released if that is what you would prefer. My guild was mentioning that you can actually stack your chests (i.e. have your season rewards add up without opening them) but I have not personally tried this yet. I will this season though.
