So I just figured out the crowd sourcing is mostly done for OG Jumpstart. People have added the JMP decks and loaded them in as distinct decks to be searched. So I can copy the deck to my deck "ideas" but I am unsure of how to mass import all the cards, which is the other thing I want to be able to do.
1) Load each deck
2) Import all cards in the deck to my inventory, with the listed printing, regardless of if I have the card in any printing or that editions printing already.
This should work for Commander pre-cons as well, once someone uploads it as a deck, any of us could easily grab it and dump into inventory.
