Tony Stark, Tech Leader

Yellow Jacket joins Iron Man to bring tech upgrades in to play to increase the hero's hand size quickly. In late game, Machine Man is a powerful resource sink for the extra cards, including one drawn by Ironheart entering play. Rapid Response and Make the call can bring any ally back to trigger their effects, especially Yellow Jacket. Adding Reinforced Suit and Power Gloves to Iron Lad boost his power even more. Another target is War Machine.
