Help on 2nd Vexen battle on Kingdom Hearts Re: Chain of Memories?

I've found that if you equip strong cards like 7's 8's 9's and 0's and some smaller cards and arrange them into sleights in your deck before the battle then you can keep executing sleights til you run out. Then use a high potion and get them all back.

Also keep breaking his cards, don't think that every sleight will just kill him, he will break the sleights when he gets a chance.

Don't forget to equip some cures and fires and some blizzard. If you have premium magic cards use them and use the extra cp to add more attack cards.

Also i found that using summons in this battle actually get broken more easily and will take up more room in your deck

Vexen's first fight was a joke. This time around, Vexen is a lot more serious, and his aggressiveness shows. He's a lot more dangerous, and he has three combo attacks this time supported by a much larger library of cards. Not only will he attack you with his weapon more of the time and also cast the Freeze spell, but he can also summon puddles of ice that will make you slip, and send out icycles that will follow you around for a while.

Additionally, he has a ton of 9s and 8s to go along with his 0s, 1s, and 2s, so don't think that you can sneak a Summon in and win easily.

Your best bet is to go with some of the strongest Summons you have, four or five Cures, a good number of Fire cards, and a lot of strong Keys.
