No ... you CAN buy Lady Deathwisper diamond version for 2,000 gold ... that is what the OP is asking.
But yeah ... I don't know of any other way to get the two cards mentioned in the first post, other than buying the bundels ... that's never going to happen in my case ... there is no way I'm paying €25 for TWO(!) card packs and a diamond card. Yes, I know that those packs are "special" with a minute chance to get Signature cards ... but no way.
