Probably fiora or riven.

Nasus or Mundo imo

any more good melee champions

I'd go with Warwick if you've got absolutely no idea what he'll play, since it's a 1v1 you can itemize against his damage and still do heavy damage in return with no offensive items.

Galio could be a good choice as well, he can poke from well out of almost every other champion's range.

Xerath? hmmm....

Darius can be a good pick but i would recommend LeBlanc

I'd say Sion he has a nice little stun and a shield to stop early game pokes but what really makeshim shine? DAT ULT

Yeah for sure a strong melee

i say go with lux if you are familiar with her abilities

to beat xerath you need someone who can trade with him. Fizz will do the job
