I'm still somewhat new to MtG, and have mainly played commander, along with a bit of modern which was a little too intense for me. What are some good formats to look into for kitchen table, 2 player mtg with my wife? Commander is great but tends to want a 4 player format.
Bear in mind we'd rather not buy new cards, but used cards and proxies are fine, got no major price constraints since I'm happy to print up a card if it's going to be too hard to find.
Oathbreaker is kinda like a mix between commander and standard. The games are quicker, so it can work better as a 1v1, but can also scale to multiplayer games.
One other option might be to pick a time period and run the standard decks of that time. So if you pick something like a decade ago you would be playing with the original Theros and the Return to Ravnica blocks. Some cards from that time might have held their value, but cards like Boros Reconer switched from $30 while in standard to like $0.6 after they rotated out.
