Osiris

When Osiris is on the battlefield Atum may be cast from the graveyard for {b}{b}. {2}{b}, {t}: Target opponent lays down one card from there hand onto the battlefield face down. You may guess whether it is a land, artifact/enchantment, nonpermanent, or creature/planeswalker. Reveal the card. If you are correct put the card into play on your battlefield face up. Otherwise, card goes back to player’s hand.
