Should I level up before beating Vexen in Twilight Town? What level were you at and what cards did you use? - vexen in twilight town

This is Kingdom Hearts Chain of Memories for Game Boy Advance. Twice I've lost, but I came to their low HP Real before his death, the 2nd Time. I went and leveled after all, because I am a card: 1 for the second door, and not, but I wonder anyway what cards are used, what was your CV and CP so on.
