While you have 4 or more cards suspended, nonbasic lands are mountains.
Suspend 3 -- {r} (Rather than cast this card from your hand, you may pay {r} and exile it with 3 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. It has haste.)
