Shineseer

Cover {2}{r} (If the cover cost is paid, Shineseer enters
the battlefield attached to target land you control. As
long as it is in cover, it cannot attack or block.
Unattach it any time you could cast a sorcery by
paying its mana cost.)
As long as Shineseer is in cover, opponents play
with the top card of their library revealed.
When Shineseer leaves cover, draw a card.
