This Nori ally perfectly complements a more dedicated Delving deck. From my own experience, there are two aims of delving: first is to get things on the board, with cards like Ring of Thrór, Well-Equipped, and Ered Luin Miner. Second is for recursive effects, such as Hidden Cache and Dáin Ironfoot. Any delving deck can do any proportion of both styles, and both are helped by cards like Dwarf Pipe, which no dwarf deck of mine leaves home without. Ally Nori also aids both kinds of delving, recurring cards from your discard back into your deck in a similar way to Dwarf Pipe. If you accidentally delved too greedily and discarded an important card without a Dwarf Pipe available to save it? Nori can put it back into your deck so you can try drawing it again. Running Deadman's Dike and don't want to bust too quickly? Nori can help, especially with all those recurring shades you'll have to fight. Need more 'delve-able' cards to discard again for stat bonuses? Nori has got you covered, as long as the enemies keep on coming.

His stats are reasonable, better with Dáin Ironfoot. And he's a reasonable addition to any deck running Tactics, especially if it's also got a way to shuffle the deck (such as the in-sphere Bofur!) If you're running any sort of deck that relies on cards going into your discard (and not typically coming back out again, like Noldor ones), then Nori is a great card to consider including, especially in those combat-heavy encounters, where you might be more inclined to pop in those Tactics events.
