Other-Worldly Discovery

Look at the top 4 cards of your library. Choose 2
and put them into your hand. Put the rest into
your graveyard. Then, if there is a card named
Other-Worldly Fear and Other-Worldly
Mysteries in your graveyard, exile all cards in
your graveyard and create a 5/5 legendary black
demon named Arazkanov with flying.
Cause spooky, scary skeletons
Shout startling, shrilly screams
They'll sneak from their sarcophagus
And just won't leave you be
