Season Rewards and Rankings Questions

I just got into faeria recently, and I am really enjoying it. However, I am wondering how the season rewards apply to your pandora rank. Are the season rewards based upon your highest rank, or is it solely based off of your constructed ladder rank? Am I able to get the season card back if I get to rank 15 in pandora but unable to get to rank 15 in the ranked ladder?

No rewards for Pandora, no matter the rank (no reset either), as for ladder : https://www.faeria.com/news/announcements/32-ladder-seasons-are-coming

There seem to be rewards according to here
