Varys, the Spider

At the beginning of your upkeep, each player
puts the top card of their library into their
graveyard.
Whispers—{t}, Exile a card from your graveyard:
Target opponent reveals a card at random from
their hand. If the revealed card shares a card
type with the exiled card, that card is discarded.
"North or South, they sing no songs for spiders."
