There's so much competition in leadership decks that this card rarely makes it in, but whenever I have run I've been pretty impressed.
I think it gets particularly valuable once you make the jump to standard 2. The abundance of overkill makes chump blocking a less obvious alternative, and in general on the harder scenarios it is much harder to reach the critical mass of allies that many leadership archetypes need to be successful. It's hard to precisely evaluate, but generally I'd value a tough over a stun, and a 2 ER tough that exhausts your worst ally is pretty good value.
I think this is a great card that pretty much nobody ever plays.
