I'm pretty new to paper Magic, just started dipping my toes in it after a friend got me into Arena.

I've found a private seller selling new MOM commander decks for around $30 equivalent, while other listings are around twice as much, give or take ($50 to $60 equivalent).

This is on eBay so I should be covered by their buyer protection in case anything goes wrong, but is there any chance those are bootleg/knockoff decks? Does anything like that even exist? If they were fake cards I probably wouldn't be able to tell, to be honest.

I should probably ask the seller if those decks are new and sealed, or just new but opened for display or something like that; although I doubt they'd admit to selling bootleg decks, that's why I'm asking you guys.

Lastly, the seller has 100% positive feedbacks, but few of them (less than ten, I think, so pretty easily faked).

What do you think? Thanks in advance!
