Funny, my bro plays a similar Shadows deck that has the opposite problem... far too few minions. I find in a 35 (with dwarf drawing) card deck, 20 minions is more than enough to just right, depending on their twilight. My bro in a 60 card deck with no drawing capabilities has 17... I edited his deck and made it a 40 card one, with 15 minions. It plays okay now, but it could use some help. But he has to do that.
