Cosreith, Anima Seraphim

Whenever you create one or more creature tokens, you may search your library for a
basic land card, put it onto the battlefield tapped, and shuffle your library.
Whenever Cosreith, Seraphim of Anima attacks, for each creature that was put into
a graveyard from the battlefield since your
last turn, return that creature to the
battlefield under its owner's control.
