Hearthstone legend ladder reward is the highest ever?

Hearthstone legend ranking vs battle reward treasure chest is rewarded according to your highest ranking of the month. Among them, every time you reach 15, 10, 5, it is said that there will be a qualitative change in the reward (an extra gold card will be given), and by the end of the month, it is easier to get good results in the ranking vs. battle (ladder).

Finally, I wish you a gold card that is not funny ('?' ))

The answer to your question: reward according to the highest ladder level of the month.
