Nature's Allure

Search your library for a creature card, and put it onto the battlefield tapped. Shuffle your library.
Suspend 10-X-{x}{g}(Rather than cast this card from your hand, you may pay {x}{g} and exile it with 10-X time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost.)
