I acquired a position in oldschool magic cards. (Haha, have watched too much
alpha investments channel.)

From here:
https://www.cardmarket.com/en/Magic

And from these sellers:
https://www.cardmarket.com/en/Magic/Users/TEMPEST-STORE
https://www.cardmarket.com/en/Magic/Users/BB-TradingCards
https://www.cardmarket.com/en/Magic/Users/HiveGames
https://www.cardmarket.com/en/Magic/Users/Goat-enterprise
https://www.cardmarket.com/en/Magic/Users/MagicBazar
https://www.cardmarket.com/en/Magic/Users/OutpostBrussels

I bought cards priced between 0 - 12 euros. All cards took max 2 weeks to
arrive.

*ALL* cards were as expected and in a condition such was promised in the
website.
So the peer-review system _works_ amazingly well, at least when you buy from a
bigger seller.

Also bought some cards from finnish POROMAGIA
