My main shock was the statistical improbability. I guess the game's AI was done seeing me putz around in the lower levels and extended a booster pack or two to move me up in the leagues with the new CP.
I thought only the older cards were to be used on the land to keep them integrated. Didn't know all cards could work the land, so that's a good thing to keep in mind since I'll want to maximize land utility myself. I have much to learn.
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.
It doesn't say much.... so, ah, you don't have that much to learn just yet.The only information I could find on land was here : https://docs.splinterlands.com/land
