[Single Card Discussion] Drafna's Restoration

[Lockdown]

I just came across this card today, and I found it to be very interesting.

Drafna's Restoration

      Color= Blue    Type= Sorcery    Cost= U    AQ(C4)
      Text (AQ+errata): Return any number of target artifact cards from target player's graveyard to the top of his or her library in any order. [Oracle 1999/09/03]

For the cost of U, return any number of artifact cards from a graveyard to the top of the library.  I'm thinking of this card from two different angles.  First, is there any way to break this with one form of combo or another?  And second, as hate against welder decks for example.  Protect your artifacts from being welded, or prevent them from welding their own big creatures into play and stack their deck in the bargain.  Thoughts?

Note: Mods, please feel free to move/lock this if you feel that this thread does not belong in the open forum, I just wanted to bring this card to everybody's attention.

I'd really just rather used Tormod's Crypt or something with a broader impact on the graveyard.  Sorcery speed just doesn't cut it for the effect, and it does not remove the threat permanently either.

I'm sure it's been looked at before, and set aside for much the same reasons.

the protection idea really isn't a good one, since the spell is a sorcery, and they can use welder in response at instant speed if they see you're taking something from them they really wanted

This would be newbie-level discussion, but that card really isn't good. Closed.
