Silver has some value. Gabe (both versions) is solid, TSA and CotH are, of course, ridiculous good, Striking Herod has 7 offense and an ITB win ability, Seraph is amazing and Seraphim and Cherubim are pretty good, and then there's Birth Foretold. Serving Angel would be good if Silver had more than 1 worthwhile battle-winner, and Angel of Warning is pretty good but only if you get rid of Naz.
So ten cards. Unfortunately, other than that, Silver has almost nothing to offer (except Gathering for some combos). Compared to other Brigades where it's difficult to use only 10-15 cards out of the Brigade, that's pathetic.
