Eyes of the Everstorm

for its tempest cost. If you do, it's a sorcery spell and is
put into your graveyard as it resolves.)
If you cast Eyes of the Everstorm for its tempest
cost, reveal the top four cards of your library,
then you may cast an instant or sorcery spell
from among them without paying its mana cost.
Put the rest into your hand.
