Sell it.
You won't be using it in an anti-FG deck anyways (assuming you go rainbow or rol/hope).
You might use it in an entropy rainbow for T50 farming, but then unupped discord is nearly as good.
The electrum is more important now. Once you start farming FGs, you'll get lots of electrum. Then you can build a quick T50 deck - plenty of discords in T50 farms.
