Valiant Sacrifice

I underestimated valiant sacrifice originally, but it's actually pretty good. It's fairly cheap, and allies leave play fairly often. Campfire Tales, Erestor, and We are not Idle are the only other leadership card draw sources that aren't trait specific and valiant sacrifice holds it's own.
