Maw of Malmortius and Mercurial Scimitar are way better items for an ADC looking for Magic Resist since they add lots of AD too.

Just compare Spirit Visage and the simple Hexdrinker. With the latter you surely lose 25 MR to SV but you gain 25 AD and the passive shield which is just what you really need to survive a magic damage spike, then yout lifesteal will kick in and bring you to safer health levels. Not to mention that you'll have saved 850g too.
