Shrine of Burning Rage has been really, really good for us. Getting this in your opening hand, or early in the game feels amazing. Kind of like how with Pack Rat, you know you've got something up your sleeve that can come out early, but will almost certainly win you the game if they can't remove it.
It's incredibly swingy, but there are a number of matchups where your opponent doesn't have artifact removal against your deck since red aggressive decks typically only have so many artifacts in the roster, or dealing with the creatures killing them is more important than dealing with the clock but then the clock kills them anyways. It's great for when you're fighting through removal-heavy decks since it gives you a clock that persists even after stabilization. Yes, it dies to disenchant, but it also kills from 7-10 life out which is absurd for a 2 + 3 mana investment.
Thanks for the suggestions, i0. My previous AKH update to this list was definitely on the conservative side, and it's time I added more AKH cards that have held up to testing. To be honest, though, I haven't gotten enough testing in with my unpowered to know where most of the AKH cards I've added stand, and a lot of the cards you're suggesting haven't really been on my radar.
Based on feedback I've seen on this forum so far and the latest episode of Antknee and Usman's Third Power podcast, though, I do feel OK with adding the following cards now:
I'd like to get more feedback on the rest as to whether or not they've tested well, so I'll put up a post in the AKH Testing and Inclusions thread and get back to this after some other cube managers have weighed in.

465 card Unpowered cube thread. Draft it here and I'll be happy to return the favor.
450 card Peasant cube thread. Draft it here.
Bloodlust Inciter is a pretty miserable card. It pretty much needs to be in your opener, with even that being still kinda 'meh' some percentage of the time. It may be the worst top deck outside of like a basic land, and even then at least my basic land will be needed in some percentage of games at that point.
Censor is pretty legit and deserves a spot. The others are a bit too borderline IMO.
*Note, Samut, Voice of Dissent only ever went in the Fires of Yavimaya deck or awful 3-4 color "stuff" decks, but I've had her carry me to the finals in an 8-man draft twice now and she's really a powerhouse.
