That CTRL-D would be your friend pushing ALT-D instead. ALT-D is clone, and is not used in LotR, but *is* used in some other card games.
As for the deckbuilder? It's OK in a pinch, but I would recommend using Zorbec's, which is substantially better. Or SdA. There's probably a way to count, but the syntax wouldn't be worth the effort.
