You build him exactly like every other AD assassin. Brutalizer and Vamp Scepter for early damage and sustain, Hexdrinker against AP, BT when in need of damage, LW when in need of penetration, and BC for even more penetration. Defensive options include but are not limited to Warmog's, Randuin's, and GA.
Boots are a situational pick. --- /|\ http://i48.tinypic.com/2pzcsv7.jpg \|/ http://www.youtube.com/watch?v=vE7x0WLz7SY
