Mana Altar

{2}{t}: Add X mana of any one color, where X is
the amount of time counters that were on this
card when it was first suspended.
Suspend X—{x}(Rather than cast this card from
your hand, you may pay {x} and exile it with 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.)
