Can you get two Wonder Collections? 😳

Most events ended on Sunday, and it's back to the usual Mayor's Cup on Monday. With 4 days left until the current album ends, and the Mayor's Cup being around the same duration, I'm putting a decent effort into the tournament with the faint hope that people might skip it if they're not interested in the trunk. By the way, as I shared in the image, I was surprised to see someone in my group with a "Wonder Collection x2" and took a screenshot. Since the Wonder Collection is a mount, what's the point of having two? You can't even merge it, and it's not a cloak item, so why??? My questions just keep piling up. Could it be, could it possibly be, that there are core players out there hopping between clubs just to double-dip on collections? 🤔
