Seems to me that the easier method is just to kill the espionage agent. He has only 4 HP, and the battlefield medic kills himself reviving the espionage agent. The main drawback is that the medic spends Steel’s turn alive before trading himself in, but since it’s turn 1 and you haven’t injured Steel or any other agents, it doesn’t matter. You end up in the same place, and you can put the bounty somewhere else, or play something else.
Of course, I’ve yet to win this one-shot, so you played better than I did overall.
EDIT: Finished it, finally. Fine, naturally.
Turn 1 I took out Espionage Agent instead of Ray Manta, play Sudden Contract to put The Ultimate Target on Steel. Battle Medic takes himself out to replace the Espionage Agent. I used Ex-Patriette’s assault rifle to whittle down Ray Manta to 4 HP, so when Matthew Hayes came out, he took out Ray Manta. Which is a typical bit of foresight from having lost the match before.
Next priority target was the Espionage Agent so Hayes could shoot Steel’s minions in the future. After that, I just focused on doing damage, Steel first. Screw “Hold The Line,” I shot Steel anyway. When Lost in the Past came out I ignored it, and never wasted an action on pulling out a Temporal Grenade.
Ex Patriette went down quickly, but I stopped worrying about things like the Envenomed Bolts on her and Greazer’s hair, and played things like Shock Rounds. By the time she went Steel was down to single digits, and when I took down Steel, Bunker and Chrono Ranger still were in the mid-teens.
Bounty Board brought back Ultimate Target and By Any Means, which I put on Ambuscade. With Chrono Ranger set up with a couple of the damage boosts he needs to make all his 1 point shots effective, Ambuscade’s health quickly dropped.
Final round had Bunker hitting Ambuscade with the Omni Cannon for 8 points of damage, and Chrono Ranger finishing him off. Both heroes were at about 7-8 HP.
