I didn't win every match with it but it's very very strong. Build is as follows: hybrid pen marks, armor per lvl yellows, CDR per lvl blues and atk speed quints and 12/18/0 masteries
and lategame replace boots with Trinity Force.
You deal INSANE damage, don't know if thunderlords decree is bugged or something but it's sick. Also you heal from ALL damage. IMO guinso's replaces BotRK for Jax now.
