In the arena the 15k and 7k(?) Might reward was 1day gk. After about 40minutes sp4z updated the rewards to 1daygk and 5 tokens. Ppl who finished the arena before that lost 10tokens. They could give you good cards if summoned right. I finished the arena before the update and didnt recive them. I submitted to kabam about that, and this was the answer i got.
