Reposition: Without any cards to speed up the Transporter, this is my go-to talent for escaping. Since I can't guarantee to hit most of my shots, keeping myself alive is my top priority.

Generator 5: You'll have a mine to throw every 2.5 seconds. Great for distracting and annoying enemies.

Amplitude 4: Your mines can reach enemies up to 180 units away. I'd max this one out on larger maps, but level 4 is good enough.

Oppressor 3: Now it can detect 4 enemies in range. I'd give one level of this to Amplitude if enemies don't huddle together much.

Quick Scope 2: Reduce the time to scope in and out by almost half. Go between sniping and looking around much smoother.

Restore 1: My preferred filler card. Great for surviving if the flankers get the jump on you.

Nimble 3: I start with this to increase my ability to reposition and escape pursuers. Cauterize can come afterward.

Kill to Heal 1: I would always have this at least at level 1. The mines can give me easy elimination bonuses and I can get back into the fight quicker.
