"Ishizu Ishtar is a good character that relies on Fairy monsters and her deck skills fall more on the LP (Life Points) regen side. Your best bet for getting better cards for her is pulling from the Neo-Impact pack set. I’d consider leveling Ishizu at least until level 20 to get her deck skill “Precognition”. When your opponents life points are double yoursyou can see the top card of both players decks. It can be helpful when you’re in need of a quick strategy."
