There are some cards that seem to be totally useless, e.g. Mythril Sword and Frog; I have never seen either of these cards coming close to winning a card battle. I think they are just there for novelty value or something. 😉
And the arrows on a card are totally random, but the arrows on any individual card never change. If you want to get the highest card collector’s rank, you need to have one of each of the 100 individual cards, and they all need to have a different combination of arrows; so it could take a long time checking all your cards have different arrow combinations. 😉
Anyway, my favourite cards… I often use Nova Dragon, Dark Matter and Ribbon cards.. can’t really remember what other cards I used…
for fun: fat chocobo, oglop….
But FF9’s is still quite fun.
