Today I had the life splinter and finished my quest in the Diamond II league. I got these rewards
Shortly there after the season finished and as I was in Diamond II ranking I got 50 chest to open. Here is what I found when I opened those chests.
I am kinda bummed I was hoping for a GF card or legendary card or maybe an orb. At least I got a bunch of DEC! 650 in one chest is pretty cool.
