GA matchups

When GLs first came out, I never thought that I would get any of them, now I have all of them. 

Good news, you’ll eventually drop far enough that you’ll face more people like yourself 

Same!....Well I don't have Tano.  I'm usually very slow at picking up new things.

To the OP, unfortunately you'll have to face them.  If GAC is important to you, you'll need to pick some GLs up (attacking ones anyway) or the few legendaries that can counter GLs.
