Overall I would rate them this way:
All DLC characters are pretty ebin, if you don't know any cards that could synergize amazing with their perks, I would suggest just reading
http://onehundredpercentorangejuice.wikia.com/wiki/Charactersand preferably checking out which class of character you would preffer - bruiser, bully, tank, gatherer, ̷s̷i̷s̷s̷y̷-̷t̷r̷a̷p̷ ̷m̷a̷s̷t̷e̷r̷ etc.
