which 4800 mid laner

Syndra, imo

Viktor/Orianna/Ahri (I think they are all 4800, really dont remember).

Xerath is really fun/good imo... totally different style to Syndra though.

These are all of the 4800 AP Champs (I think): Ahri, Brand, Cassiopeia, Diana, Elise, Fizz, Malzahar, Orianna, Syndra, Viktor, Vladimir Xerath, Ziggs, Zyra

If you like playing Lux And Veigar, Probably these would be your best bet (my opinion) Brand, Orianna, Syndra, Viktor, Xerath, Ziggs, Zyra

Ziggs and Xerath would probably be the easiest to pick up. But Honestly I would go for Syndra. She is alot of fun.

Personally I am going to try not to buy any champs in the store. Just try and get lucky with my Loot. SInce Blue Essence is fairly rare to get, I want to save as much as I can.

Ahri, Orianna, Zyra, Syndra, or Malz.

Also Katarina or Anivia if you want something cheaper.
