Yeah, all the characters who have Calculator are villainous. That's why they're starting the trend of using traits to give wild card abilities to the likes of Constantine and Nightwing.
And yes, he copies TA with the wild card ability. The other part of the trait is what lets him copy a keyword.
I read the whole card and the part of him being able to take KWs for some reason just didn't sink in. >.<
After having my head surgically removed from my a**, I realized this and now I like this fig even more so than I did before!
