I am familiar with TCG basics, dabbled in Magic, played many boardgames. I am curious about Lorcana but so far all I know about it is that it's a Disney themed TCG.
What makes the game intriguing to you? What are some unique aspects of it? Anything you don't like about it? How much do I have to be into the theme to enjoy it? How much would I have to spend to enjoy the game 2p with my partner?
I haven't bought the game yet, but I am mainly just interested because of Disney theme. Have you looked at the cards?
As for how much to spend to enjoy the game 2P, just buy 2 starter sets. That's pretty much all you need. Of course you can keep buying different decks and something called booster cards (which I am not completely sure what they are 😀 ), if you want.
