Guillano's Psychic

When Guillano's Psychic enters the battlefield, look at target player's hand.
{6}: Name a nonland card. If a player has that card in their hand, exile it. You may cast it for as long as it remains exiled, and you may spend mana as though it were mana of any color to cast it.
"I don't know when my psychic joined. I guess he made sure of that."
