Coming back from Kara last night I took a ride through Stormwind (you know the drill; hearth out then realize the quest hand in was back at the instance) when I spotted this chap. Now, as someone who has a substantial collection of mounts I was entranced and a bit of investigating showed me it was [Swift Spectral Tiger], only available (boo!) as a result of a uber-rare (1 per 500 boosters) loot card from the CCG.
(The odd picture angle is because I'd ridden past before the uniqueness of the mount and I didn't want to run back and gawp like some sad mountaholic. Oh, too late ...)
