MTG isn’t (currently) as bad as things like Pokémon with the scalping and collecting. Building tournament ready decks can cost you a lot of money but they sell tons of prebuilt regular and commander decks you can buy for ~$30-$60 and just play with your friends. This is sort of the standard for casual play with friends, which is the kind you’d be into if you’re comparing it to Uno or Catan. If you showed up to Commander Night with your buddies sporting a $500 hand built monster deck they’d turn you away at the door.
