A nice guide, just have a few suggestions. You might want scaling blue MR glyphs as you don't take magic dmg until at least level 4 and the dmg isn't going to be heavy until late game. Also i would suggest an abyssal scepter and banshee's over rylai's and FoN just because it is cheaper, still gives you the same dmg output. no slow but it reduces magic resists of enemies and gives you more MR with a little less hp.

but overall a good guide...check mine out if you want as it might help you out with a few ideas
