Cloudcover Titan

Cover {1}{u}{u} (You may cast this card for its cover
cost. If you do, it enters the battlefield attached to
target land you control. It cannot enter combat while
in cover. Remove it from cover any time you could
cast a sorcery by paying its regular mana cost.)
{3}{u}: Return target creature to its owner's hand.
This ability costs {2} less to cast if Cloudcover
Titan is in cover.
