So I just got into this game and I barely have a feel for it, but im not sure what to get for my to be aggro deck, i want to run riku (i dont know which one is the best one) but all I know is Im pretty sure you need Sephiroth and Oblivion. Please help anyone. Thanks

also what is a joat deck?

well a joat is a jack of all trades. it mixes WR and Aggro together and work as one. and as to your question riku lv3 is good. and you gotta have soul eaters in there.

Joat = Jack of all Trades or basically you can WR or Agrro your victory (usually are close to 50-60 cards)

Aggro

Player Card

Riku

you'll see why in the attack cards

Attack Cards

Soul Eater (takes off two HP and can ONLY be used by Riku/Dark Riku)

Oblivion

Friends

King Trition

Beast lvl 3

Tigger

Cid

Sephiroth

Chip and Dale

Moogle

and other types of cards that allow you to win challenges/ pull cards that allow you to

Magic Friend

Simba lvl 4

Bambi lvl 3

Dark Cards...(my advice on this comes from my only personal experience

3x Behemoth

2x Parasite Cage

2x Sleath Sneak.

World Cards...

usually

Destiny Island is all you need

Hope this helps, If you have any more question feel free to ask

You should also look into Monstro Lv1 (it locks off there friends) and Alice lv0 (it kills their friends) and Phil (they can't use Magic)...look into some control cards for some great advantage over your opponent.

Donald lvl 4 and Stopra combo works well here too..cycle through as fast and as well planned out as possible to re use those soul eaters..and of course that's well Chip and Dale is there

Ive done some studying and shouldnt i use the king or ultima?? (assuming I can get my hands on them)

Yes, but pulling SRU is a pain, (I've only pulled three) so without them having them it beating a deck that ulitizes them involes serious skills/ combos

you can make a good deck without the SRU's but most of them are very good and trying to pull them also means you got more cards in general. Trying to get them is never bad and most of the time you will get 1 (sometimes more) in a box.

Aggro seems to adopt many styles in this game. my suggestion. look on the old forums and look at the good aggro builds and see what sort of strategies there are and go from there.
