Remorian Workshop

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.)
{t}: Add X mana of any color to your mana pool where X is the number of time counters on all exiled cards. You may use this ability while Remorian Workshop is exiled.
