Hexproof, Trample, Vigilance
{x}{r}{r}{r}-Deal X damage to target vehicle.
This ability can only be activated while Imperial
Titan is a creature.
Spectacle {10}{4} (You may cast this spell for its
spectacle cost rather than its mana cost if an opponent
lost life this turn.)
If Imperial Titan is cast for its spectacle cost,
it gets +2/+2 and becomes a creature in addition
to its other types.
