How do you defeat the queen of hearts in Kingdom Hearts

It's not a matter of actually defeating her in battle butmore like defeating the trials she sets against you. First you have to collect the clues that are scattered in Wonderland (total of 4 boxes).
Box 1:Antenna
Box 2:Stench
Box 3:Footprints
Box 4:Claw Marks
You don't have to collect all but by doing so you higher your chances of selecting one of these when you talk to the queen of hearts. Depending on how many you collect and whats inside will decide how difficult the fighting will be. When fighting you want to avoid the card soldiers and just destroy the tower.

Of course this isn;t the last boss you will have to fight to finish this world, there is also the trickmaster, but that's a completely different matter.
Hopes this help!
