Eden, Ever Changing

Discovery for artifacts 2. (Exile cards from the
top of your library until you exile an artifact
with mana value 2 or less. Cast it without paying
its mana cost or put it into your hand. Put
the rest on the bottom in a random order.)
Whenever another creature dies, venture into
the Basement. (Enter the first room or advance
into the next room of a dungeon that starts in
"The Basement".)
