I looked on the central and saw a long list of AV and AZ bosses. Some of those are inside dungeons and gauntlets, which are not time-effective for farming.
Others are impractical because they are ornery or difficult for my school to deal with (I'm storm).
Still others may be good candidates but I haven't tried everyone.
Has anyone been farming for this card, and if so, who is the most cost- and time-effective source?
