I thought about it but then dismissed it for now because it isn't terribly effective yet. Right now there is a lot of attachment destruction and I just don't think it's a good idea to use up your gold. I would wait a few months so you can use Govern the Land/Near Miss/Border Market.
Border Market means you can get those cheap attachments back easily. Near Miss will either pay for an attachment, since they are all cheap, or protect one. It's legal now but just that one card isn't enough imo. Govern the Land you can use to either get back something like Venerable Master/Chugo Seido/Second City Dojo or to get back one of your items/followers.
