RE: Finally Struck A Legendary Gold Rush Right At The Finish Line

Hmm, I'm not sure we have any certainty on land... but my understanding is that any card could work the land, with bonuses provided if the card is higher level, rarity, gold foil, edition, etc.

The only information I could find on land was here : https://docs.splinterlands.com/land
It doesn't say much.... so, ah, you don't have that much to learn just yet.
