I think this is a question to confirm if this might be one of the items they add for a limited time to the loot-tables again. They did so with others.
I don't see why they wouldn't have limited time drops on items that were removed but then returned in the casino.
It's no different than Scimitar of the Mistwalker dropping. Please add this item with the pre-nerf CoS, the fungus staff Kunark set.
