I'm down to 7!

[Afay]

I'm down to seven cards that I need for my EDH, and I'd really appreciate some help getting them:

{Crucible of Worlds}
{Reanimate}
{Sylvan Scrying}
{Attrition}
{Dread Return}
{Buried Alive}
{Demonic Tutor} (preferably Revised due to price)

Any help with this is greatly appreciated!
