How about:

Sorcerors, RoA, Archangels, Athenes, Rabadons.

Your RoA will provide some nice HP, and you can get armour from yellow runes and MR from blue ones (and Athenes). Your Archangels will provide a suprising amount of AP since you also have RoA, and Rabadons is a must-have. Athene's is also a must-have for the CDR and infinite mana. Last item can be something situational, usually Void Staff if they are smart enough to build resistances, or if you feel like you need tankiness and survivability you can go for Zhonya's, Guardian Angel or Rylai's.
