Stuck on the Shadowy Figures stage, it's the stage before the very last stage of that chapter. I keep getting killed by those annoying catapult things at the back of their line. It takes 3 maybe 4 catapult launches, and my team is dead. I have tried many different formulas to mix and match, but I'm lucky if I make it past the first wave. Any ideas? If it helps, my first and second teams are listed in my signature below.
