How do I play Corki?
Lately I've been seeing people take adcs to the mid lane. I don't know if that's a good strat, but it usually leaves our team without ap. I could go with a mage, but I figured someone like Corki would do fine. Problem is I have no idea how to play him. I assume that you go with magic pen runes like a mage, but from there I'm lost. What masteries does he take? What does he build besides Triforce and boots? What are my combos, and how do I use the package without killing myself?
