The Reins of the Swift Spectral Tiger summon a Swift Spectral Tiger epic mount.

Source

This item comes from a special loot card from the Fires of Outland set of the World of Warcraft Trading Card Game. The loot card unlocks the option to buy it from Landro Longshot <The Black Flame> in Booty Bay. The mount costs 100 .

The code also unlocks the option to purchase a non-epic standard mount; [Reins of the Spectral Tiger] at level 40.

The odds of pulling a Spectral Tiger Loot card out of a Fires of Outland TCG pack are speculated to be around 1 in 7,260. The first Spectral Tiger card sold on eBay for $2,000. Cards currently sell in the range of $500 to $800 on eBay.

Unlike other loot cards in WOW TCG sets 1 and 2, this loot item requires you to spend gold to acquire it. This is because the loot items are not supposed to affect gameplay by giving a player an advantage over another; thus, it merely unlocks the option to purchase a different mount rather than giving a free mount.
