I noticed Skytread had 3 defense; and went the defensive route with him. Flamewar and Breakdown make good teamies for this. Ideally; you want to swing with the tank first to try and get it KO’d. Hopefully you get Peace Through Tyranny early so you can KO it yourself; then swing with Skytread on your extra turn! Failing that; put lots of defense boosting Upgrades on the plane, to keep the damage on it down. Flamewar is the only bot you need to flip; the others just stay in their starting modes.
