Sin Prodder is really hurt by having the damage based on cmc. In red aggro decks the damage is going to be about 1.2-1.5 a turn on average. Combined with the mediocre body, no deck is really looking to play it.
Yeah, some of the lieutenant cards this set are good for 1v1.
I played Kari-Zev for FNM this week since I haven't been able to play it much. I ended up losing to Glittering Lynx both games round 1. The next three rounds I won against players with bad or unrefined decks.
I'm also working on a Kari-Zev list for Duel. Most of the changes I made are the obvious two drop for one drop swaps. I should finish the list and start play testing it in the next two weeks.
I don't have much experience with 30 life, so take my opinions with a grain of salt.
I think Mox Amber will continue to be good in 30 life.
Goblin Chainwhirler's eternal power is very meta dependent. I think swapping out Keldon Champion for him could be a mistake, the cards serve very different purposes. If you feel Keldon Champion wasn't pulling enough weight then feel free to cut it.
Ahn-Crop Crasher is a pretty good three drop. The only reason I would consider cutting him is if my opponents were not playing many creatures.

I finished building my list two weeks ago, but haven't been able to test much. I'll post my thoughts and the list once they're a bit more refined.

I think Viashino Pyromancer and Lightning Mare are good. I'm very skeptical about Volley Veteran.
I don't have an old list anymore, but there are a few on mtgtop8 from when DC was 30 life.

Anyone can see from looking at the list that I'm a fan of the heavier creature builds. Some notable creatures that I'm not playing are Goblin Guide, Grim Lavamancer, Monastery Swiftspear, Soul-Scar Mage, Spark Elemental, Vexing Devil, Firebrand Archer, Harsh Mentor, Phyrexian Revoker, Smuggler's Copter, Young Pyromancer, Chandra, Fire of Kaladesh, Sin Prodder, Zo-Zu the Punisher, Keldon Champion, and Fleetwheel Cruiser.
Since I'm playing a lot of creatures, there is a lot of instants and sorceries that I skip on.
Some notable one drop spells I'm missing are Brute Force, Collateral Damage, Firebolt, Forked Bolt, Galvanic Blast, Landslide, Lava Spike, Pillar of Flame, Reckless Abandon, Reckless Charge, Seal of Fire, Tarfire, Shard Volley, Shock, Titan's Strength, and Wild Slash.
Some notable two drop spells I'm missing are Chain of Plasma, Fire Ambush, Flame Jet, Flame Rift, Fork, Incendiary Flow, Reverberate, Smash to Smithereens, Thunderbolt, and Volcanic Hammer.
Some notable three drop spells I'm missing are Acidic Soil, Browbeat, Char, Collective Defiance, Flame Javelin, Flames of the Blood Hand, Kari Zev's Expertise, Rhystic Lightning, and Wheel of Fortune.
Last from instants and sorceries are Stoke the Flames, Elemental Appeal, and Violent Eruption.
Finally, there are a few non creature permanents that I'm not playing. Notable ones are Blighted Gorge, Fetches, Teetering Peaks, Ankh of Mishra, Break Through the Line, Impact Tremors, Pyrostatic Pillar, Throne of the God-Pharaoh, Blood Moon, Grafted Wargear, Spellshock, Tangle wire, Manabarbs, and Koth of the Hammer.
There is probably some stuff that I missed, but I think I covered a lot.
You shouldn't expect to flip Garrison. In a vacuum, the damage they do per turn looks like this.
Goblin RabbleMaster 1,6,7,9,11 etc.
Hanweir Garrison 0,4,6,8,10 etc.
I think Rabblemaster is better, even though garrison has one more toughness.
