Buying TCG items with gold?

[upc523]

I was doing some browsing around google in search of a place where I could buy a lot of TCG items. I found plenty where I could use RL money but I was more in search of a place where I could use WoW gold instead. I came across a few forums selling winged guardians, steeds, etc but all on certain servers. I was curious if anyone on here knew of a place where the TCG items could be bought with WoW gold?

Any input, thoughts, information is greatly appreciated as always!
