Build Wonder Man's ATK through Aggressive Conditioning, Brute Force, Combat Training, and Ionic Physiology/Power Recycling and just don't make any basic attacks for the entire game. Don't worry, there's still plenty of damage to go around (and some spicy thwarting).

Once Wonder Man's ATK is sky high (up to 9 with all relevant upgrades in play), use Unified Strike to add his ATK to an ally's attack. Dust, Thor, and Two-Gun Kid all attack multiple targets when they attack, so the increased ATK hits multiple targets at once. Perfect for multi-villain scenarios or ones with large minions. And finally, Push Ahead along with Wonder Man's 2 THW and 2 DEF will be able to thwart quite a lot no matter what you're thwarting. Be sure to swap often so you can keep replaying Unified Strike over and over with the help of his Signature Sunglasses.

Outside of the above outstanding combo, you can also utilize Starstruck, Quick Strike, or Smash the Problem to use that super high ATK. Specialized Training is primarily for Surveillance Specialist to thwart and draw cards when you don't have any of the various events to use your ATK stat without making a basic attack.
