Worse Unleash the Hounds but works with Bolster. (which is never used) Also most of the decks in meta would have 2-4 minions in board (except zoo and aggro) so this card is trash.
You know you can make your opponent overextend and dump his hand when you need it ? It's called "skill" and that's why UTH is so strong if played by a good hunter player.
This isn't "worse" than UTH, it has the same activator but different synergies, and is more reactive so it fits warrior just as good as a more proactive UTH fits hunters. And taunt isn't worse than charge. It's not better either.
Anyway, UTH has always been borderline broken/problematic card, if this is slightly worse than that, it's still a good card, and a more healthy one, so we should all be happy that it's not a BETTER Unleash the hounds.
