Probably a good move if it was a spare kitty!
As long as you have enough summoners for land coming up of course.
I think LAND is going to rely on CP a lot, cramming as much in as you can, that's why I'm currently buying up cheap cards!
I should really consolodate my BETAS and UNTAMED now TBH. It's a good time, cards are cheap!
Can't wait to see how Land will work. That should bring a ton more excitement to the game!
