EDIT: The following was based on a misinterpretation. =P
People are likely to be annoyed when it summons itself.
Ignoring that and looking at existing Uncommon Horde cards, this one will grant you recruits in the value of: 16 20 18 0 (20) 0 15 6 0. So taking itself into account, you have exactly half a chance (presently) of gaining recruits in the double-digits. Not too bad.
It seems that this would be useful outside of a Horde deck. Maybe even more useful. Decks that have Orc Regiment as a finisher might benefit from taking this to try to draw it (or another high damage card) while gaining a large fraction of its cost. Even if you draw something less than stellar, the 15 wall is probably going to be useful.
