Tudoya, Deep Reef Witch

If you would mill one or more cards, surveil
that many cards instead.(Look at the top X
cards of your library, then put any number of
them into your graveyard and the rest on top
of your library in any order.)
Whenever you surveil three or more cards,
create a black Aura Curse enchantment token
attached to target player. It has, "Whenever
enchanted player mills a card, they lose 1 life."
