In agreement with Kotono, there are less than 5 days left in this event so you won't be able to make much use of the ticket unless you just want a chance at an event-limited card to keep, though that probably won't help you much either.

Do bear in mind though that the system states your tickets can expire within a few months, so "When the pimp's in the crib ma, drop it like it's hot~"...you get the picture.
