You can try
. She's really bursty and has a long-range dash with resets. You need to be careful or else you'll burn through your mana pool really fast though. Also Riot's having a promotion on their Facebook last time I checked that if you like them on Facebook you'll get a code that unlocks Trist as well as her Riot Girl skin for free.
Or you could also pick up my personal favorite,
. Who boasts considerable burst damage, good AS steroids (And one he can share with his teammates). And can be played as a pseudo-caster (AKA the Blue Build), which focuses on flat AD, on-hit and CDR which means you can E pretty liberally, Pepper enemies with Qs, and throw out TONS of ults, while still having a pretty powerful auto attack thanks to Muramana.
If you're feeling ballsy, give
a shot. With Draven, he can have some of the highest DPS in the game. It's all in the mechanics, he snowballs good. Once you catch axes reliably, you will be PISSING damage. In terms of mechanical skill however Draven is certainly the hardest of the AD Carrys.
Or. You know, you could just play
who's freelo and will never get nerfed because of her rabid fanbase.
