I might bite the bullet, I'm getting bored of playing only sword and I would like to see how the other side lives.
I'm kind of waiting until I open one more (i'm still opening the original set for the albert ticket), but I'm pretty sure rune really needs 3 A&G 3 Kuon 3 Dclimb to be viable in diamond - sword has a lot of cope cards you can run that are closer in power (excepting gildaria), but rune's legendaries don't feel replaceable.
