Mystical and Radiant are printed, and are mid-playtesting
They had some OP and super-weaks, and we've balanced them to be more fun. The 2 games we played this weekend were great
There is a new rule for weapon attacks. Consume any number of energy sources, draw that many cards, and pick one. Dump all of them, and deal damage to the foe equal to the use cost of that picked card. - It gets you out of sticky situations by letting you deal some damage, and it can be quite brutal, but not OP. I think it'll be final
It's still an either or for Weapon attacks and using Attack cards.
