Sorry to sound upset but,
Magic penetration in this game is abysmal (no pun intended).
Haunting Guise is Riot's eye sore/redhead step child of mage items.
(Can't believe they removed the CDR on it at one time, it still doesn't build into anything and it is more expensive than the Brutalizer that stacks with the Ghostblade. *Yeah Armor Pen. vs. MR Pen.)
Abysmal Scepter offers some defense and is in the right direction but its range of area effect is situational and cost is just expensive.
That leaves stacking Sorcerer boots and you wouldn't believe how many players feel that is a trollish build.
The famed MR items rock thou:
Quicksilver Sash - 56 MR with a clicky effect that is better than cleanse
Odyn's Veil - 50 MR, 10% Magic damage reduction And a clicky nuke
Hell, I would settle for the MR on JUST ONE
of the above items, either, pretty much nix's the effect of all 3 Magic penetration items listed above. (I think the funniest part is that the Quicksilver Sash is cheaper than the Haunting Guise.)
But the argument that the Void staff and Stacking AP is best has been made a tremendous amount of times on the SR Forums. Err did I say SR forums I mean General Forums.... geez how could I make that mistake *roll eyes*.
