Three very different cards for Supergirl, and since she will likely be your heavy unless you use Jimmy Olsen to get her and Superman you will want to build your team to use the ability to its utmost. "All in the Family" makes her tough to knock out with a villain deck, but they added language for your own villains, so a card with splash damage would be negated on her making it more useful, however no such villain power came in this set. "I have all your powers" adds insult to injury so you can pile on more dice after striking your opponent, but you will need to create ways to keep your opponent from blocking her. "And finally we have "Guarding National City" which will keep your health up if you are falling behind. If you go hard on buying powerful characters and know you may take damage from a faster cheaper team this health boost may flip power back in your favor and now the fast cheap team has to deal with some devastating consequences.
