I've thought about magic pen and ill try it and the gunblade is just what i upgrade the revolver to late game its the last thing i buy just for the extra ap and sometimes i use the slow on it the other two items i just put in there as other options for magic pen. Like i said some times the Mejai's just wont work so ill switch to void or scepter and sometimes armor for Zhonya's isnt needed either but like most players know you have to change with each game. Anyways thanks for your input

I think you should go for magic pen marks but that is just my opinion,
Also why a gunblade? You don't need the AD life steal. Just thoughts.
