I have collected all but 7 trading cards for my collection, but two of the cards I still need, I'm not sure how to get them. They are the Calvin Blackmoon Trading Card and the Tail Lash Mahar Trading Card.

Anyone know how I can get these, or do I have to buy them from user shops?

Tail Lash Mahar Trading Card is from "Luminaire 2009: Holiday Shop item", not sure what that means but its retired so you'll have to buy that one from user shops. Not sure about the other one.

[edit]Calvin Blackmoon Trading Card is a prize from restock Wars, you'll also need to buy it from another user

Luminaire holiday shop items have been released through a specific quester (can't remember which one) during December. However that card was changed, so it no longer seems to be holiday related and probably won't get released that way.

The Calvin Blackmoon card might eventually, someday be released through the crystal shop.
