Max all cards you're using for AUB, as long as they're at HSR and above.

Most people (given that you're not going up against a dead/newb alliance) have at least 1 maxed G/HUR in their deck -- from my experience, regular GURs can kill everything, unless a GUR on the other side procs awakening. Whcih happens a lot more often than not, as RNG likes to screw with everyone. It's still best to max all your cards you're using, although I'd probably start with the G/HSRs and work up.
