If you refine a card e.g.a character card can you get it back or there isn't an other in the game?

No, I dont believe you can get the card back. Especially if its a character card, those cards are one of a kind in the game.

theres this whole thing about being able to get every card on the ragnorok in disc 4 but I dont think it is true.

I know that if you play all the CC members, they appear on the ragnarok afterwards right?

*shrugs* I never liked the card game

Maybe you can get the lost card back from the Card Queen. Well, at least I think you can. ^^

If you did the quest of the CC group and the Queen of cards, in disc 4 you can re-gain all the cards by challenging them

sadly I spent ages, collected all character cards and a good few Gf cards, then messed it all up by refining the laguna card for the final battle.....out of the 99 holy wars i got i think i used roughly 12.

You can get every rare card on the Ragnarok on Disc 4 as much as you like.Fact.

What do you have to do, or are they always there no matter what?

Yes, every time.Various members will have different cards and play by different rules but you can get EVERY card back as much as you please.

the random rule is a killer.

Sure is.Cost me many a card until I got rid of the accursed rule.
