Ixilan Shipyards

As long as Ixilan Shipyards is fortified, vehicle
spells you cast have "Suspend X - {1}, where X is
the mana value of the vehicle spell. (Rather than
cast this card from your hand, you may pay {1} 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.)"
