Some ideas for Karen McCormick.
With Kenny's brother getting a card I thought of a few ideas for his sister.
Parasite Karen. Race Sci-Fi
Puppeteer parasites are something common in scifi.
Art: The pic would be a smaller Karen riding on a zombified character back with he tongue plunged into their neck.
Low stats but as a warcry it attaches to another card enhancing them by adding her stats to that card and providing a speed boost as long as they are alive
Gothic Karen: Epic Fantasy
Basically the idea is a witch girl.

Flying and ranged. gets a hit points and damage bonus every time an ally dies.
