Ironborn Trapper

Flash
When Ironborn Trapper arrives on the battlefield, look at your opponent hand.
Choose a card from it and your opponent reveals
it. If the choosen card is a land, that player puts it
on the top of his or her library, if it is a creature
card, on the bottom; and if it is neither a land
nor a creature card, he or she puts it in his or her graveyard.
