Yeah, I'm liking the common and rare ones too. I am testing them out in the Kryptogamers tournament and they're performing well as well. As for disturbing the balance, I have seen a lot of posts in the SPL discord how a lot of the Epic cards are too OP.
I'll check your post out.
I'll give a further look into the Epics then. Until now, they haven't convinced me at all. Thanks for the hint!
The ones with debilitations have insane stats. The battles can be over before the negative effects really hurt the team. Additionally, they are pretty much the king in Back to Basics ruleset, with a few of them being OP in little league.
