Did you know that Karthrus could also go Adc but go AP? But I agree with your choices.
It works with his Q to poke but I only use with someone goes AD Mid like Zed or Talon. Works very well just need good support on your side. It's like Yasuo and Alistar or Maph. It's a good time unlike vs Rengar and Ivern Bot. Gonna have a bad time. Too OP
Ez makes sense due to this E not sure you could config to dodge major ults with his E am still not able to access it yet but am very excited to try out the program
Lee Sin is an amazing Pick imagine over smiting Dragon or Baron. Savage move. I never thought about Nidalee nor Elise doe.
I like your three picks. Ashe melts along with Jinx, but I never got into the new Tristana just yet. Would like to learn more about Aphelios and Xayah they are still very New to Me.
Forgot about Khazix His a very carriable champ has an assassin. How about Kayn cause I been main-ing him a lot lately. He cant carry late game doe tried. His too squishy.
