Which of these champs should i get please help.

Yea, it depends on play style. You threw in a loaded deck. Each champ has the own design to the game. With out knowing what you like to play I would say shorten your list, watch some game play of them or wait till weekly rotation comes out and play them, then decide.

That really depends what type of champion you are looking for, what type of playstyle you like.

your still only level 25 so i would stray away from the harder champions in the list but aatrox is fun akali is strong right now caitlyns a good safe adc pick wouldnt go draven unless you wnat to spend the next 200 games practicing him fizz just dont for the love of god just dont irelia is a bit overloaded but not too difficult jinx is good if you know how to position properly and kite jhin is strong and where you are his weakneses prob wont be exploited kat is faceroll and tons of damage lelbanc it will take a few gmaes but only around 10-20 malph is really good nidalee i would proably wait on till you can get more experienced orriana is difficult but now would be a good time to pick her up if you want to learn her renekton is fine rengar again would wait till you get more experienced same with vayne and syndra so I've put your list into three cats
