Khercix the Prophetess

At the beginning of your upkeep, look at the top
of each player's library.
Enchantments you control have shroud.
Whenever a creature an opponent controls
attacks you or a planeswalker you control, you
may return an instant or sorcery card from your graveyard to your hand. If you don't, they return
a land they control to its owner's hand.
