Deciving Item

{1}{r}: An opponent chooses a card name of a permanent you control. Then, reveal the top
three cards of your library. If one of the revealled
cards has the chosen name, put that card into
your hand and the rest into your graveyard.
Then, create two treasure tokens and sacrifice Deciving Item. (They're artifacts with "Tap,
Sacrifice this artifact: Add one mana of any color.")
"Uhh, yes, it is magical! It can see into the future!"
