Hi, following up on my previous post, I've got a more concrete idea of how rearrangement works, and this method has been proven to work for both mine and Demeter's deck.
With this method, you can arrange not only which 6 cards you want to show, but the exact order you want them to show.
Please note that I have a 43 card deck, and Demeter has a 45 card deck. The last time I used this method, I had a 27 card deck. Therefore, I don't know if this will work for smaller decks (...it should, though), and I do not guarantee that because it worked for both Demeter and I, that it will work for you too.
Main Method:

Okay say here is your deck:
Lv5 Oo
Lv2 Uu
Lv3 Bb
Lv1 Xx
Lv4 Yy
Lv8 Zz
Lv7 Aa
Lv2 Cc
Lv7 Nn
Lv9 Pp
Lv3 Dd
Lv1 Tt
Lv5 Mm
Lv8 Rr
Lv2 Ee
Lv6 Ff
So the cards that are displayed are: Lv5 Oo, Lv2 Uu, Lv3 Bb, Lv1 Xx, Lv4 Yy, Lv8 Zz
Say you want instead, this order: Lv9 Pp, Lv8 Rr, Lv7 Nn, Lv8 Zz, Lv7 Aa, Lv1 Tt
Okay then find the cards you want to switch and sell and rebuy them like this:
Step 1) sell Lvl5 Oo, sell Lvl9 Pp, buy Lvl5 Oo, buy Lvl9 Pp
Step 2) sell Lvl2 Uu, sell Lvl8 Rr, buy Lvl2 Uu, buy Lvl8 Rr
Step 3) sell Lvl3 Bb, sell Lvl7 Nn, buy Lvl3 Bb, buy Lvl7 Nn
Step 4) sell Lvl1 Xx, sell Lvl1 Tt, buy Lvl1 Xx, buy Lvl1 Tt
Step 5) sell Lvl4 Yy, sell Lvl7 Aa, buy Lvl4 Yy, buy Lvl7 Aa
Now you probably have this order: Lv9 Pp, Lv8 Rr, Lv7 Nn, Lv1 Tt, Lv7 Aa, Lv8 Zz
You can rearrange within your top 6 too.
Step 6) sell Lv1 Tt, sell Lv8 Zz, buy Lv1 Tt, buy Lv8 Zz
and you should have the correct order. ^^ Of course, you just have to apply the same pattern to any 2 cards you want to switch. You can only switch 2 cards at a time- although there should be a way to switch more than 2 at a time, this method keeps it simple and consistent and leaves less room for error. ^^
What if 2 cards do not switch?:
Spoiler
Sometimes when you apply this method, you will find that the cards have gone back to the same spots as before! Well, this happens (and I don't know why) but some cards can switch with each other, but some cards cannot. For example, Lvl1 Wolfram and Lvl5 Edward would not switch for me.
What then? I tried switching Lvl1 Wolfram with other cards, and found that Lvl1 Wolfram would switch with Lvl9 Nakajima. Therefore, to replace the two cards that do not switch, you may have to do the following:
-Card A and Card B do not switch
Step a) sell card A, sell card C, buy card A, buy card C
Step b) sell card C, sell card B, buy card C, buy card B
Now card B will be displayed where card C used to be. ^^ I find that generally if two cards' levels are close, their chances of being able to switch are higher.
Important Tips:
Spoiler
-You must sell and rebuy!! Sending to a friend and having your friend send the card back will not work!
-If your card is out of stock, you run a risk. Here's a tip on how to rearrange a sold out card (it's still risky though. You can lose your card, so only do this if you are willing to take the risk)
-You MUST wait until either a "card sold" or "card bought" message shows before moving on to the next step or the rearrangement may not work.
Buuuut if the page crashed or the browser did not load after 10-15 seconds, run to the window with the sold out card and buy it anyway. Then wait until you catch your breath to retry the sell/buy method.
If neither card is an out of stock card, then take your time to make sure each step has been completed before moving on to the next one.
Okay, that's it! Please let me know if this works for you as well, or if it does not. If you need help, I'm on IRC every day in the #aarinfantasy channel, so I can always look at your cards and help you arrange them. I can only help people on IRC, though, so please do not PM me asking for me to rearrange your cards for you. ^^;
Good luck! ^^
