To start, I looked at a bunch of Hollow One lists to get a general idea of construction and built my own version of the typical lists.
First Iteration
I wanted to go all in on the self discard part of the plan to get aggressive with Greasefang. Because of the random nature of Burning Inquiry and Goblin Lore, I wanted Unearth to get Greasefang/Asmor back from the grave in case they were discarded. I cut Flameblade Adepts, Ox of Agonas and Vengevines as they were the cards I felt synergized least with the Greasefang plan.
Second Iteration
The deck lacked early game power and Kitchen Imp felt lackluster. After asking around for suggestions at my LGS, the two most common answers I heard were Flameblade Adept and Seasoned Pyromancer, both of which I'd been thinking of.
I cut the Kitchen Imp and threw in Flameblade Adept, because I felt the Seasoned Pyros would make the curve too high. The deck immediately had a higher win rate. Flameblade allowed me to get super aggressive in the early game and turned my discard spells into more than just discard.
Third Iteration (Current Iteration)
The deck felt a lot better, but I didn't have a good midgame, especially when I didn't have the Greasefang plan online. I also had trouble finding both pieces of the Greasefang combo, but it would've won most games if I had. Finally, I occasionally didn't have enough mana.
After examining the list, asking around at the LGS again to confirm my suspicious, and some soulsearching, I regretfully cut my favorite cards in the list; the Blazing Rootwallas. The Rootwallas just didn't synergize with the rest of the list, especially because I didn't have Vengevines. They never contributed meaningfully to combat and always felt like a bad draw.
I relented to the curve issue and tried Seasoned Pyromancers on the premise that they draw cards lategame, dumped the cards I wanted to, and created multiple bodies. I also added another Mountain to accommodate the red influx and to help with mana consistency.
This is the iteration I'm currently testing; and results are very promising
