When looking at your decks, either in the Mobile or Desktop version, is it possible to rearrange the ordering?
They appear to be listed in the order they created.
I don’t want to have to keep deleting and creating decks just to bring my new ones to the front of the list.
There is no official option to order your decks.
The most used workaround for this is to open a deck and change it to wild, close it, then open it again and change back to standard. This will put the deck at the bottom of your standard decks list.
It follows the same idea as deleting and creating the decks, but slightly less complicated.
