Mistakes happen. I hope @thegcc returns the 10 land plots. That sure is an interesting story of how cards were to be leveled up by use. It would definitely be something I would not mind doing, but I do understand that they wanted to keep cards valuable in-game.
I also think that the new system where you can play extra cards after seeing the line-up will make gameplay much more competitive and interesting. I wonder if they will have a level-up system or a limited use feature to ensure that the land cards are valuable.
