Chapter Master of the former Astral Claws, Tyrant of Badab, and Pirate Master of the Red Corsairs, Huron Blackheart has a deep background, and an interesting entry in the new 6th edition CSM codex with a bunch of special stuff. That said, in some ways he does seem to be a pretty standard Chaos Lord, in spite of all the special stuff! (i.e. his price is roughly comparable to a well-kitted out Lord).
Firstly, and perhaps one of the best reasons to look at Huron, is his automatic warlord trait: Master of Deception. Having up to 3 units in your army able to infiltrate for free is a good boon. Moreover, this kind of trait might play well for Alpha Legion players who'd like a themed Lord / counts-as Lord. Indeed, it'd also do well for Night Lords as well.
The Hamadrya is an odd accessory. Every turn, Huron gains a random psychic power. This might be really good and situational, or it could just be a load of rubbish that can't be used well on your turn. But, hey, we're playing chaos, so a little randomness is okay.
The Tyrant's Claw gives Huron a decent strength in melee, and an important AP3 statistic to help him wade through space marines. And if that's not enough, he has a power axe as well to help deal with any pesky terminators who dare show their faces to him. His sigil of corruption will be coming in handy there as well, I feel.
The built-in heavy flamer is also a cool addition. Woe betide any unit that charges him.
So, in short, I think Huron is basically an interesting Chaos Lord that comes with a reasonable price tag and a set of mixed gear.
In terms of tactica, I think I'd play him one of two ways: (a) in a unit of assault-orientated marines (or even terminators) and head for the heart of the battle as soon as possible. The infiltrate rule could help with this goal. Or (b) I'd be thinking about sending him in alone to completely disrupt opponents firebase or objective holding units (i.e. nominate himself as an infiltrating unit!).
The only real down-side is that Huron is still a marine, and will die as such to las cannons, power fists and the like. Without Eternal Warrior, he could well perish very quickly if the sigil of chaos fails him. Hence his deployment is quite situational: it may be better to place him in a large block of marines when facing heavily armed opponents.
