They are meeting gamers half way here. You know where you can get the cards you want. You better believe there would be a massive premium if you could scoop up booster of cards that are currently in a ship purchase. Are there rules about having to use the actual cards printed by them for tournmament play?
It doesn't help your brick and mortar store you play at, but I wouldn't turn someone away as a game organizer. Hell, put them in sleaves and no one will know.
Print-On-Demand is not Print-At-Home. The print on demand stuff is just a series of offerings that allow them to quickly have cards printed when they are ordered, in small quantities (aka on demand).
Locally the tournaments allow proxies. Most of the card art is out there. If you want to use four stealth devices, you really shouldn't need to buy two firesprays (unless you want two). Proxies are not allowed in the official rules, and won't be allowed at the world championships at FFG, so it's mixed. I want a huge fleet, so I have all the cards I want and need. I'm always happy to loan a player a card they need so they can have the real thing. I do hope they come up with a common upgrades cards Print-On-Demand pack or two. Maybe an upgrades pack and munitions pack or something.
