Just reviving the Hybrid Kayle build post-patch. Lots of flexibility in things like the purchase order and last item. Other possibilities for the last item are Infinity Edge, Youmuu's Ghostblade, and Rylai's Crystal Scepter. You can also look into other quints, but fort seems best for early survival. Celerity glyphs are another option. As for skill sequence, the reason I pick up Divine Blessing at 5 is for movement speed only and then don't worry about it till late game.
