That's where I started, too, but chase that white rabbit a bit and things get even more interesting;
A trusted, transparent charity verifies ownership of an account, and announces that they'll auction off the contents of one (and only one) booster pack every month for the foreseeable future.
I'd be bidding on those cards.
I want my publicly visible collection to demonstrate my charitable nature; and I would certainly anticipate that when big players arrive they'll be willing to pay me a premium for those cards, so they'll not only retain their value, they'll help bolster the price the charity gets each month at auction.
The more noble, trustworthy and transparent the charity, and the more sparing and certain their schedule of opening packs and selling cards, the higher the premium we can expect.
Combining cards would add a whole lot of other owner names to the list, but the charity would still be one of them.
I can even imagine people deliberately building a Max common including dozens of different charities' cards
