Yawgmoth of Phyrexia

Indestructible, Trample
At the beginning of each upkeep, exile target creature. At the beginning of the next end step, return that creature to the battlefield under your control. That creature gets +2/+2, and is a black artifact creature in addition to its other types.
If Yawgmoth of Phyrexia would be put into your graveyard from anywhere, shuffle it into your library.
