Broken Down and Analysis:

Friends –

Level 0 – Abu and Alice are both unneeded and wasted. Abu because you don’t need to see your oppenent’s hand and if you do you have Pinicchio. With only the three main deck types in it’ll become easier to pick off the cards in their hand as you play against them and learn what their commonly used cards are.

- Search Cards are needed (Wendy, The King, The Mayor,etc) Tidus to clear their level friends. If you have it Chip and Dale is good to recover materials without having to cycle through your deck.

Level 1 - Donalds and Magic are really not needed as Cure is easily able to be Tinker Bell and with Phil around your magic cards are wasted. Goofys are rather weak and there are better options. Beast and Hercules are good with this deck. Jack is needed. Pan is good. If you have them Tigger and Cid are good. Moogle even can be used. PHIL….negate their magic and combo with certain cards makes it a trip to get around.

Level 2 – I really don’t like the level two set up here for many reasons. The most disturbing of them all being it’s like Déjà vu. Parasite Cage ….no one takes it into consideration anymore…These things hurt. Yuffie isn’t great even with her return ability. Chesire Cat relys too much on if you can play good amounts of Dark Cards if not Jack is needed as it has the same magic value, a support value and a decent effect. King Triton is good if you got it. Pan lvl 2? Fairy Godmother, as much as I don’t want to mention this, would probably be a good idea.

Level 3 - Beast x1 (L&D), Pan good, Hercules (ADA) and maybe Jack …your good.

Level 4 – Sephiroth is good. If you can get a Cloud, good.

Magical Friends – Tinker Bell lvl 3 can be Tinker Bell lvl 1 and/or 2. Both are easier to play. Same for Dumbo. Bambi I recommend lvl 1x1 and lvl 3x1. Simba lvl 1x1 3x1. My reasoning being that WR deals with just dark cards and stalling…that is the secret. Aggro you have to control the whole board.

Magic – No real support. Phil

Equipment Cards are too situational.

Attack Cards – Oathkeeper (believe me I’m not joking) 5 support same as D Rose and an Ability for Wring.
Oblivion – 10 support.

If you got Ultima Weapon great...if not no loss.

Dark Cards- The only decent card I see really is Behemoth. Everything is either too weak or doesn’t do enough. My Suggestion is get some Parasite Cages (You should have kept Dragon Maleficent) and more Behemoths. Invisibles are good. Barrel Spiders are good.

World Cards –

Lvl 1 = D Isle (Destiny Islands) great to search out search cards, tidus, lvl 0 cards. D Castle (Disney Castle) drawing is good, even though you can overdraw and it’s basically Wonderland lvl 1 without the discard and with a no dark cards shield. Olympus Coliseum is a good lvl 1. Monstro lvl 1 for aggro/control is good.

Lvl 2 = Atlantica is a good choice to stop aggro’s Soul Eater. Deep Jungle lvl 2 powers up Dumbo’s effect. Neverland lvl 2 or Halloween Town lvl 2 (never both) would be good for first turn.

Lvl 3 = Traverse Town lvl 3, End of the World. Never play them first turn.

So that’s basically it….an outline of my suggestion for a balanced deck would be something like:

Player
Sora lvl 2 (L&D)

Friends
Level 0: Chip and Dale, The Mayor, Wendy, Tidus.

Level 1: Jack, Peter Pan, Tigger, Cid, Beast, Moogle, Phil
Level 2: Jack, Peter Pan, Fairy Godmother, King Triton,
Level 3: Jack, Peter Pan, Beast (L&D), Hercules (ADA)
Level 4: Sephiroth, Cloud

Magical Friends
Level 1: Tinker Bell, Simba, Dumbo, Bambi

Level 2: Tinker Bell
Level 3: Bambi, Simba

Attack
3x Oathkeeper
1x Oblivion

Dark Cards
2x Invisible
3x Behemoth
3x Parasite Cage
1x D Mal (Dragon Maleficent)

Worlds

Level 1: 3x D Isle, D Castle, Monstro

Level 2: 2x Atlantica, Halloween Town/Neverland, Deep Jungle

Level 3: 2xTraverse Town

This is just what I would think. I tend to stick with either Racing or Aggro. Play with it ..if you don’t have the cards there are other cards that can be used. This is just an example deck.

You can try this if you can if not look through other cards..best way to learn what works and what doesn’t is to play with the cards.
