This is the latest in the series of cards with a similar effect; 2ER upgrade, Response: satisfy a condition, discard this card > ready your hero, such as Battle Fury, Justice Served, or Indomitable. Ready to Rumble is basic so it complements any aspect. Every hero can satisfy this by flipping from alter-ego form to hero form. Heroes that like to flip such as She-Hulk can find a use for this card. Heroes with multiple forms such as Spectrum or Ant-Man will get the most out of this card. As more flipping heroes are introduced this card will increase in value.
