Beneath the Ground

Reveal a creature from your hand. Look at the
top 6 cards of your library. You may reveal any
number of creature cards that share a creature
type with the revealed card and put those cards
into your hand. Put the rest of the revealed cards
into your graveyard.
The Skaven have little desire to conquer. They only
seek to destroy and defile, ransacking cities and
consuming farms with no intent to occupy them.
