ill answer your input now thanks.
this build is ment to be tankier. not a TANK. your aiming for magic pen/ tank. if you put merch threads in there u lose magic pen. originally i did use deathcap. However i took it out do to the price of it dont scale. Rylais is not bad early game. But when you can still one hit people with your ult its not as needed till they can get away. and actually thanks for the deathcap mention. i didnt relise i hadnt removed that yet. i took at out of my build do to its to expensive for dominion. dont pay off.

The build overall seems.. odd, but it does look viable. You say you get Rabadon's Deathcap in your items section, but you didn't put it in the cheat sheet. I would recommend replacing Void Staff with it. Also, you don't mention nor recommend Mercury's Treads. Easily the best boots in the game, they can really help out with Katarina's CC problem. More magic resist can't hurt either. Third, you say that Rylai's Crystal Scepter isn't useful if you build it first. That my friend is completely wrong. Early game health, AP, and a slow to get you through the early game really helps you get fed for your tank items. I would recommend getting it before or right after Abyssal Mask. And lastly, your grammar is off in multiple areas. Try using a spell check program to pinpoint their locations and fix them. It can really make the guide easier to read.
