There hasn't been much discussion about the pre-release.
What character is winning of the 5?
What cards are integral? (my money's on Financial Distress and Lion Slayer)
What cards are frequently pulled?
I'm assuming, in a format where resource restrictions are ignored (assuming you do it that way), King is the best, seeing as how he has access to Paul's, Kazuya's, and his own Throws. Nina's probably up there.
