I forgot to mention that after a duel(if you win), you get a card.

and their is a neat free duel to earn cards and star chips

FREE DUEL is when you can duel people you beat.

You may decide you want to forgo the grind and just play the Campaign straight through, but since you only receive a single, usually unhelpful card for each duel you win (and a meager handful of Star Chips), it's pretty much impossible to get through some of the tougher duels without grinding Free Battles for at least a few quality cards

Mai Valentine ALWAYS gives the best stuff, so be sure to battle her in free duels

The dueling isn't that fun, and it is so rare to come by magic or trap cards

Soon after it started getting boring and the dueling was really horrible

Normally (unless the computer is feeling generous, which isn't often), u have to win about 20-50 duels against a single person, sometimes more, before they give a rare card.

So if you're planning to get an awesome ... deck, DUEL HIM

See, there's this guy that a dueled about 70 times in free duel mode

There is also a ranking system that takes place after every single match, and it ranges from D all the way to S, and every time you win a duel, you get a card to add to your collection

Later on however the duels get very tough

If you have any hopes of reaching the end of the game, well, you better be prepared to spend hours in Free Duel mode, because if you don't, you're not going anywhere

If you need starchips, you can get some by using the FREE DUEL mode

i say dark duel storiesis 100x better then this game i've excpect better from konami

Duel the so called "Meadow Mage" in free duel over and over

that it gets so tedious dueling people over and over and over and...sorry.

Free duel is the best part to me.

See, what I did, was first beat him and then save and go to free duel
