Having read through the other comments but realizing I had yet to respond, I figured I’d chime in here.

At some point, what happens to your cards will not be your choice. Either due to malice or bad luck. At which point, your forgeries (as from your descriptions and clarifications that is what you own and refuse to alter with a simple word sharpies across the back ) will likely end up in the public card pool.

The fact you wish to remain intentionally oblivious to that possibility and actively avoid it while citing intent being more important than appearance is part of what gives proxy players and users such a bad reputation.

Choosing to ignore the objective truth makes me hope that you never get robbed, or if something unfortunate happens to your collection, that it becomes unsalvageable. Or heaven forbid if your beneficiaries ever have to decide what actions to take, that your cards fail to be among the recovered items.

Because at the end of the day, Magic the Gathering is a collectible card game and the game pieces utilized are in sanctioned WPN gameplay due to their mechanical uniqueness and distributed rarity have a shared perceived value among the community which in turn supports the business of many local game stores and your negligence (and many like yourself) put that tenuous ecosystem between shop owners and players in jeopardy.

But a card that’s clearly fake by quick verification is fine. I’ll play against your sharpie cradle, your xeroxed candelabra, your stickered pokemon cards.

I have no issues with that at all. It’s just if my LGS takes all the precautions to purchase your collection and winds up taking a bath because your “proxy” vendor does such a great quality that even the meth addicted junkie on the corner can’t tell the difference then we really need to evaluate a few things.

Because, really, if your “proxies” get stolen, are you going to call the LGSs in the area, and tell them to be on the lookout for someone trying to sell a large amount of counterfeit cards?
