After a bunch of playtesting, I decided to cut a forest, a Stinkweed Imp, and a Scavenging Ooze. I found that I was getting enough lands really consistently, and with all the ways to dig through my deck, more often than not I was just filling my yard with lands, which meant I would either have to spend more resources exiling cards before swapping with the Inverter of Truth, or I would just have a crappier deck after the swap, neither of which is ideal. I cut the imp because, while it's nice to fill my graveyard, this deck doesn't benefit from it quite as much as dredge, so I found I was often opting to draw rather than dredge, and at that point the card loses a bunch of its usefulness. Still useful overall, so I kept three, but am considering cutting one more. I cut an ooze, because even though it's quite useful, it felt a little bit situational, and with the aggressive gameplan I have, I often didn't have the one green mana available to exile the card. Still helpful, especially in the aggro matchup though, and later on to curate the graveyard, but not enough so for a 4 of. I replaced these cards with one extra Tasigur, the Golden Fang and 2 Snapcaster Mages. I put the Tasigur in because I found that delve was the most consistent and effective way to curate my graveyard, and the benefit of a big body as early as turn 3 was often huge. I found I was sometimes making my library out of suboptimal graveyards because I wasn't able to curate them quickly enough, so hopefully this helps to remedy that. The snapcaster mages (shoutout ZendikariWol for the suggestion) were included because I felt that I could use the extra consistency early on, and the ability to re-use digging effects or removal seems very useful. Outside of that, I just made changes to the sideboard, adjusting for the decks I found I had problems with (token generators and storm, primarily).
More to come as playtesting continues!
