Dwarven Sellsword

I can't imagine wanting to spend the resources to keep him around, so he is likely to be a one-shot effect for 1 resource most of the time. He reminds me of Spirit Bofur, who gets played a bit as a re-occurring event, that adds 2 will power to the quest. But this guy isn't re-occurring in a good way, and you have ot play him in the planning phase.

It's possible, in a Dain Ironfoot environ it might be playable. Having this card in your deck might improve your first turn responsiveness, at the mild cost of usually being a dead card after the first round or three.

I'd never say he's a dead card.  At 1 cost, he is amazing for his stat range.  At two cost, he's still good.   At 3 cost he's finally in the range where he competes (stat wise) with other character.  However, I do understand that he's always going to be costing more and more, so eventually you'll let him go.   I think 2 rounds is sufficient.  Early game he is good, especially in a dwarf deck, due to being cheap and good stats and counting as another dwarf.  Late game, he's still fine because you will only need him around for a few more turns anyways. 

I completely overlooked the dwarf-counting thing. If you're playing with a few 5-dwarf effects he could be even more useful early on. Especially with Thorin, where there may well be a slice of time when he basically pays for himself, by being the fifth dwarf. That plus Dain has him sounding quite playable.

He's pretty awesome in a deck with Grima/Dain/Nori. Slap Keys of Orthanc on somebody and the Sellsword essentially comes into play for free (off Grima), generates a resource with Keys, and enables all the other Dwarf synergy (Legacy of Durin, the unique Dwarf allies, etc.). You basically GAIN +1 resource for a 3/3/2/3 body. Then you can either discard him at the end of the round (no great loss, since you played him for better than free), or keep him around and use Zigil Miners/ We Are Not Idle to build up Dain's resources.

As a general rule of thumb, any ally that costs 1 resource and is able to attack/block is pretty playable. Most every deck can use a few chump blockers now and then. This guy is way above the curve in the right deck.

Dwarf decks need to get rolling before they become ridiculous.  This guy is great because he has decent stats for 1 resource and he triggers all the dwarf synergy.  He's a great tempo play for a dwarf deck.  In a Dain deck he's great even as a 1 and done since paying 1 resource for 3 points of a stat is amazing even if it doesn't stick around.  In non-dwarf decks I wonder if he's worth playing.  He's still on par with a lot of 1 cost events that would achieve a comparable effect so I think he's still good.  So right now I'm of the opinion that he is great with dwarves and just good in a general deck.

Yep, that's where I see him also.  

Waiting for an attachment to blank the text box of an ally. For this one, a couple of tactic allies, some elves, and above all... HERO BILL THE PONY!!! #PleaseDevsMakeTheDreamComeTrue

Except you wouldn't be able to attach an attachment to blank no attachments as you'd need no attachments blanked in order to attach the attachment. So such a thing wouldn't make for a Pony Hero alas.
