Please answer

I beat the Queen of Cards on 4th disk. It wasn't easy though. Just save it before you talk to her (on the World Map) and then challenge her. She will prolly use 2-3 rare cards each time, so you should have a lot of other rare cards to counteract (since one of the rules is random) Keep trying and always try to get plus, and you'll win. It will take a while though.

i got all the cards and beat her very easy

On the 3rd disk, the Queen of Cards is really easy to beat, it's just that it's totally boring.

Try to avoid the Random rule and probaly elemental and then you will win like the card queen is some beginning player. Make good use of plus and same, as well as the combo rules and you'll beat her in no time. ^^

She IS a beginning player. I never got any trouble beating her, except from on the 4th disc.
