When we are creating a deck or updating one, it happend often that we remove a color for another (like replacing aventure by Mystical).
When we are doing that, the game reorder all the cards to put the actually used color first.

But this action take A LOT of loading times, and most of the time, is useless. It's actually very boring, and add charge to the server.

So I propose to reorder only when we quit the "Edit deck menu" (or just totally remove it), and keep the list of the card as it was when we are browsing it and updating deck.
