Chain of Memories Premium Cards?

I have a question out of curiosity. I finally beat that damn parasite cage so you can ignore my Pinocchio thread. Anyway when I battle heartless I get this thing that has me press A as it scrolls through my cards and whichever it lands on is now a 'premium card'. My question is what does that mean? What does a premium card do?

 

If I'm not mistaken, premium cards are stronger, but they don't come back when you shuffle. Or something like that.

 

They do come back, but I have noticed that they don't every time. Because one of my first cards to become premium at least since I started playing again after giving up on it for at least a year because of getting stuck at the parasite cage, was the cure card and I have noticed that I don't always have a particular one that is a seven, my highest one ironically my others are twos.

Not that I pay a whole lot of attention to that since the enemy is the more important focus obviously, so I could just be missing it or not see it because it's broken.
So I guess maybe it doesn't ALWAYS come back.

 

I dunno, something prevents you from getting them back. Maybe when you use them in a sleight?

 

that card is the same but it is cheaper to put in a deak so it is better if your number 9s are p

 

a premian card is cheper to have in you deack than a normal one so they are good to have

 

Read this I got your answer for Ya!!

There's nothing strong or weak about the cards. All cards in the game are determined by points, and those points are for how much cards you can hold (the better the card, the higher the points). The cards that are premium, their point value is lowered so you are able to add more cards to you deck (the more premium cards the more stronger cards you are able to have in your deck.). But they are be all means NOT RELOADABLE!!! So once you use them they are gone for good till your next battle. I recommend you don't use these in boss battles (maybe just 2 if you have o add more cards to your deck) and don't rely on them to much. If your whole deck is premium your pretty much screwed.
So keep battling and leveling up so you can able your self to add more cards without the continous us of the premium cards. Kingdom Hearts:COM cards is like a big gamble, you got to lose something to gain something, and premium cards are a huge example of that.
BE CAREFUL OF THEM!
