No matter who I change it to it is staying on the seasonal shaman. Any tips? It seems to be a glitch
Try to set only one skin as favorite 
or copy/past the deck again
If you mean the skin of a particular deck then delete the deck and recreate it.
This is a bug that happens from time to time. Some decks just refuse to keep the assigned skin and revert back to the standard skin.
