First off, I was surprised at the number of cards, I wasn't expecting 14 of them.
Here are my thoughts:
Heroic Rescue: I like it, not sure I would choose it over Dodge, but I would definitely choose it in addition to Dodge. I think it gets a bump with Zoey.
Combat Training: Kind of meh. Guardians don't normally need a boost to fight if they have high xp weapons. They also tend to be short on resources. The access to a dex boost is unusual for Guardians and I like having that
