Pressing Exploration

You may cast Pressing Exploration as though
it had flash if you sacrifice a creature or land
as an additional cost to cast it.
Mill 1, scry 2, surveil 3, draw two cards and
discard a card at random. Exile that card
instead of putting it into your graveyard.
Until your next turn, you may play that card
if you surveiled this phase.
Buyback—Sacrifice a creature or land.
