Improvised Graveyard

Flash. Enchanted land gains shroud.
When Improvised Graveyard enters the
battlefield, reveal cards from the top of your
library until you have revealed three lands. Put
the revealed lands into your graveyard and shuffle
the other revealed cards back into your library.
Madness {0} (If you discard this card, you may cast
it for its madness cost instead of putting it into your graveyard.)
"At least they can rest in piece now."
