Once youre confident with the rules and have a better idea of how cards in different colours can work together, you can then go on to build a Lorcana deck yourself, using your starter deck as a starting place to swap in new cards before you build something entirely from scratch
I would actually encourage you to do the same because your disk will get rid of them, and you are already running 33 lands so that probably puts you a bit behind from the start or midgame (or so I imagine)
How often does the MTG card count increase
Black and green have their fair chunk of indestructible baddies and, finally, blue and red boast pretty minor features
Lastly, it doesnt shuffle from your graveyard back into your library, allowing it to be abused by a reanimation effect or brought back with something like Den Protector
In fact, players should inform other players that its a proxy when its not obvious at first glance
