With the fall of Twin and the rise of UR YP durdle decks, I'm going to tweak on Dos Rakis a bit.
Since I last played with the deck, we've gotten some very important pieces:
Bloodsoaked Champion,
Eidolon of the Great Revel and my new favorite "BREAK ME!" card,
Mardu Ascendancy.
Eidolon replaces Ash Zealot, Bloodsoaked Champion replaces Rakdos Cackler / Stromkirk Noble, and Ascendancy replaces Chandra's Phoenix / Ashenmoor Gouger.
I'm playing
Zealous Persecution in place of Searing Blaze for 1-sided board wipe against Delver / Affinity and possibly Pod, and a pump against decks running Electrolyze, Forked Bolt and Pyroclasm.
I dismissed Mardu Ascendancy upon reading the first line, then recently noticed the activated ability to give my whole team Bolt/Anger of the Gods protection. Plus, in a deck so dedicated to attacking, free tokens seem nice.
You know who loves free tokens? Falkenrath Aristocrat
She also likes free recurring Humans. I expect she and Bloodsoaked Champion are going to have a nice time together.

The mana probably is too white heavy, and the removal mix could use some Slaughter Pacts (maybe in place of Bolt, the 4th ZP or the 4th Mardu Ascendancy). 24 land may be too high, 22 or 23 is probably better.
There is some flex in the deck, this is all just a thought exercise and a place to start brewing.
I expect this will be weak to Burn in G1, but some Dragon's Claw could fix that. I might just be faster than them
but time and testing will tell.
