Dichotomancy

Oracle text

For each tapped nonland permanent target opponent controls, search that player's library for a card with the same name as that permanent. Put those cards onto the battlefield under your control, then that player shuffles. Suspend 3—{1}{U}{U} (Rather than cast this card from your hand, you may pay {1}{U}{U} and exile it with three time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, you may cast it without paying its mana cost.)
