I can put that chart on my to-do list.
I think you're right about Lorna being good. She even got a new great sneak card (Stitch Leech) to add to her sneak deck, and that has higher damage than the ones she used to play. Malric is also good I think.
Of the Chaos Legion summoners, Thaddius comes out best at very low mana because of Windeku, and Tarsa when mana is around 15-20. (Though this is stats with unleveled cards, I dont know how things change with leveled versions).
