And how many of these do you think people will BUY? That's the key thing. I doubt that you'll see enough buyers on a realm (that won't just buy it for $10) to make any reasonable return for anyone.
Either way, of course, it doesn't impact the economy, since the gold is coming from players. It's no different than adding a new weapon that drops in a holiday event. In both cases, players can get them and sell them, but the gold has to come from others.

A useful followup from Blizzard:TCG Loot card mounts like the Spectral Tiger have been BoE for a long time now (since patch 3.2), and that was and continues to be well-received, and as far as we've been able to tell hasn't had any adverse impact to the game or economy - despite them selling for sometimes astronomical amounts of gold.It’s potentially worth noting that no new gold is being introduced into the game's economy with those mounts or the new Guardian Cub pet.Our goal with the Guardian Cub is to provide alternative ways for players who don't want to spend real money to add these pets to their collection. Even though this has been available a while now with the TCG mounts, this is obviously a new kind of way to deliver Pet Store pets, and we're definitely interested to hear your feedback and ultimately see how this will play out.
