Guard Armor
Location: Traverse Town
Spoils: Guard Armor Enemy Card
If you are at Level 5, this battle should be very simple. If you manage to get the Special Card (Green card with Mickey's symbol) use it to paralyze Guard Armor which leaves him open to attacks. Heal when you need to and simply just attack, you probably wont need to use any combo's.
Axel
Location: Castle Oblivion
Spoils: Fire Magic Card
To do the most damage, keep your distance and use the Blizzard Card. When Axel uses his Flame Wall attack, use a few cards to card break it. Summon Donald and Goofy when you need to and simply attack.
Jafar-Genie
Location: Agrabah
Spoils: Jafar Enemy Card
You cannot hurt Jafar, so just like in Kingdom Hearts 1 you have to attack Iago. The platforms move up and down you need to judge when the pillars will move. When you get the Special Card use to raise all the platforms up, which will make hurting Iago easier. If you keep to the opposite side of Jafar he should rarely hurt you. This isn't a tough fight at all, its just hitting Iago can be quite tricky.
Cloud

Location: Olympus Coliseum
Spoils: Hades Enemy Card
This card be a very hard battle, for Hades moves fast and uses lost of attacks one after the other.

Location: Wonderland
Spoils: Trick Master Enemy Card
If you keep attacking Trickmaster he will drop the Special Card and when he does use it to summon a table, which you can stand on to attack him causing more damage than normal, be careful as the Trickmaster can destroy the table, just keep that in mind.
