We all currently play on mtg:arena on steam. The website works in conjunction with steam so you show off your decks. You still have to buy the cards you want from someone else's deck but iirc there's a way to do that from the surveil.cards site too
Hmmmm. These are explicit magic cards. Neat! How is ownership determined or how are macthese played?

Indeed! There are TCGPlayer purchase links for individual cards and decks, as well as the ability to print full decks with accurate card sizes.
