New Loot Cards in Next Set: Servants of the Betrayer
Servants of the Betrayer™ won’t have the standard common rarity MMO Loot™ item. Instead, it will be the first expansion to feature a super-common MMO Loot™ item. In March of the Legion™, we made all the Loot™ items easier to collect, and we’re taking it a step further with the super-common Loot™ item in this set.

The fifth set, Servants of the betrayer (Set for 2008) will contain 3 new loot cards:

Papa Hummel's Old-Fashioned Pet Biscuit
The most common item or "super-common MMO Loot item" as UDE named it (every Servants of the Betrayer booster box is likely to have two MMO Loot cards), is a biscuit that will be used to feed your cosmetic pet, "the pet will grow in size. Its final size will scale depending on the model of the pet, but a general reference is to the size of an average animal hunter pet. So imagine something like this."

Weather Machine
"The uncommon Loot item for Servants of the Betrayer is a Personalized Weather-Making Machine. An in-inventory clickable item, the weather-maker will generate a personalized weather graphic that appears over the users head. The weather-maker will generate a number of different weather graphics, from sunbeams to thunderstorms. Wherever you go in Azeroth, the weather will be yours to command."

Nether Rocket
"The Nether-Rocket flying mount functions like standard flying mounts in the MMO. Like the Spectral Tiger, when you redeem the rocket code, you will have the ability to buy the rocket flying mount from Landro. You can buy the standard (60%) speed increase version or the epic (280%) speed increase version. Also like the tiger, your character will first need the appropriate riding skill before it can use the mount. You can choose to buy the standard version first and then return to Landro with the same code to buy the epic version."
