Delteros

As an additional cost to cast this spell, you must sacrifice 3 Sky Krystal creatures or artifacts on
the battlefield.
When Delteros enters the battlefield, target 1
card on the battlefield, 1 card in the Graveyard,
and 1 card on either player's hand. Exile them.
When Delteros leaves the battlefield, return
target Sky Krystal creature from your graveyard
to the battlefield.
