I wonder if they will put those old cards that aren't as good in battles as part of the land stuff.
That's something known already. No details, but there will be staking of cards on buildings. And older cards, GF, will have better bonuses.
The rarity does look like it will annoy people though.
Rarity for plots was something known. There is some annoyance about new potions for improving the chances to reveal better rarity and land category (magical/occupied) plots.
