Glimpse the Cosmos
{1}{U}Sorcery
Look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. As long as you control a Giant, you may cast this card from your graveyard by paying {U} rather than paying its mana cost. If you cast this card this way and it would be put into your graveyard, exile it instead.
