I went down the Action route; and picked Sergeant Skywarp and Thundercracker for his teamies since they like (Secret) Actions. Though, Mirage will still be triggering when he flips to alt most of the time. Skywarp can net quite the nice mix of Secret Actions in here too, with 9 different ones. All blue, except Swerve (which will give you two cards if it hits either Mirage or Skywarp and possibly do 2 damage if it hits Thundercracker), Defensive Formation (which is good for defense even if it is orange) and Even The Score (which lets the Cons get revenge!). Mirage will be quite tough to kill with Secret Actions likely to be on the battlefield.
