im a beginner and quite the noob and i was wondering what would be the best champion for me. I really enjoy assasins because of their speed and crazy burst and am looking forward to getting a new character. I usually play right or mid lane and am currently using alistar, hes ok but really slow but i do like his tankiness. Looking forward to your help and comments, thanks alot.
The best kind of assasins if you're looking for fun are the ones with resets. So Kha'zix 
is definitely a good one. Akali 
was my personal first assassin and has stupidly large amounts of spellvamp if built right. Last but certainly not least, if you're looking for burst, mobility, and the chance to outwit your opponent at every turn, there is only one: Leblanc
If you are looking for a cheap assassin I would either go 
or 
. They both have very fast burst and are quite fast fighters. But if you want some more info on all these assassins go watch their champ spotlights
Akali hands down is the easiest and deadliest assassin to pick up and own with, she's also not much IP if remember correctly. You can play her top or mid, she utterly destroys low elo games.
Good Luck; and Have fun =D
Kassadin was my first and most favourite Assasin, since he has not been mentioned here yet. Costs for Kassadin are 3150 IP :)
beware: not everybody can play/build him right
and
sound good for you. Shaco is less expensive, btw.
fizz is a ridiculously strong assassin. his burst is some of the highest in the game, his end game cooldowns are decent, and he has some pretty great mobility. in a game where you get fed as him, you can instamelt them from full with just your q and e.
Diana
is also really fun to use. her pre lvl 6 is kinda bad, but after she destroys the world. btw her ult is essencially a spammable, high damage gap closer.
