I have had a lot of good games with drawing ideas from this guide. Minor changes to the 2 rune pages. I prefer Demolish and Presence of Mind as an example. Could you please elaborate on the Nashors Tooth. I rarely build it, since in most games I go Sheen first and then LichBane or DivineS, which makes Nashor's Tooth fit worse in (IMO) as second item than Demonic Embrace or Titanic.
I also have optional items for MR like Wit's End and Maw of Malmortius.

Can you talk more about the combo to short/long trade?
