These items have nothing related to mana hungriness like Unholy grail does. There should be an unique effect related to mana restoration. Maybe a short duration active that reuturns mana equal to damage done and grants attack speed? Note that these might be built on any champion type, not only carries. It can be like a selfshield based on maximum mana, might be good for squishy carries but also some fighters especially for mana hungry ones in top lane.
