He is a pro player and a fairly popular streamer (he is quite informative). He played top lane (now midlane, if I'm correct) mostly.

He devised (or made known at least) a build in which Katarina bought Sunfire/Warmogs into magic penetration items. The concept behind the build being that if she can survive in the middle of a teamfight and keep on getting assists and kills she actually ouputs a decent amount of AoE damage and she is sort of hard to kill since she gets damage reduction from Shunpo. The build is has fairly low burst but if you actually get enough assists the sustained damage is ok.

It is sort of gimmicky in S4 since the new masteries don't work with it (the magic pen in offensive tree being so high up) so try it at your own risk.
