That's not a bad lineup. My rule of thumb with these games is that you should atleast have 1 big body on the team since they usually have higher durability and will survive longer. Wolverine is also a good one cause he slowly regenerates health and when you build him properly can even tank a little too like a big body. Use ISO-8s (the crystal jawns) don't worry about trying to be optimal with them. Just use them even for simple buffs for the characters like e.g.: Increases character vitality or durability by x etc.
If you start playing again feel free to hit me up and I'll help you beat him.
