Linus Van Pelt, True Believer

When Linus Van Pelt, True Believer enters the
battlefield, search your library for a Plant
creature with mana value X or less, then exile it
with X time counters on it. If it doesn't have
suspend, it gains suspend. (At the beginning
of your upkeep, remove a time counter. When the
last is removed, play it without paying its mana cost.
It has haste.)
