The Triumvirate Reborn

Search your library and/or graveyard for up to
one "Alexandrite, Legion", "Katherine,
Cognitomancer", and "Rye the Devourer", and
add them to your hand, then shuffle your library
if you looked through it. If one or more cards are
added this way from your graveyard, exile a land
and lose five life.
The sky breaks. The oceans boil. The mind curdles.
