Emblem Diamond master

Hi Good new year I do not get the emblem of master of diamonds season 4 when I get to diamond master

You will only get the Diamond Master emblem, if you reached Diamond 5 in season 4. If you didnt get the emblem then its you didnt reach that rank.

If you did reach diamond 5 in season 4, then Try searching for it in the card companion app here https://gearsofwar.com/cards

either you missed it in the inventory or its still being distributed. Dont know really.
