On kingdom hearts 2 hades paradox I had 15000 and lost it all im so ticked off what should I do

Well I had to try this twice and so it is actually a pretty easy battle you just have to know what to do. The first time you tried you probably got past round 11 so don't do those again just start there. Now use stitch for every round (you should be able to use him twice)... immediately use his limit Ohana! And just use ukelele the whole time... if you do this twice every round you should get 15000 points easily. Round 11-20 is solo but you can use drives and summons freely so use stitch the whole time. You also have points that you lose every time you take damage. Keep an eye on these specially while fighting pete... just use thundara on him from a distancd and you should be fine. 21-30 you have Donald and goofy back, no summons, no drives but you can use limits (try to have 15000 points by now... it should be easy). 31-40 one of the easier sections. Just use final form the entire time because you have 10 mins and it just destroys everything it touches. It might seem intimidating but it is pretty easy. 41-50 you have no friends, summons, drives... just trinity limit and magic... trinity limit doesn't do much but I will put great emphasis on using magnega then thundaga... its a very good strategy. This is easy overall but pay attention to round because it is cloud leon tifa and yuffie put together. Just keep gliding around waiting for openings. Ignore cloud who will just be flying around slashing and leon who can't do practically anything. Go for tifa first because she is weak and stays away from the others. Then go for yuffie who just makes her shuriken big. Then go for cloud using thundaga for most of his damage because he won't block it. He is pretty weak so just whack at him. Now leon goes down rather easy he is just stubborn and won't die. It is a very long but easy battle. If you follow these rules you shouldn't have much trouble with this cup
