Fair points on Darigaaz, Clique, and Melira. I think that I have enough other persist enablers to not run Melira, but I can see the value in Clique. I only have 7 other persist creatures, but 9 enablers (one only works with Finks, though). It's not like those cards are breaking the bank, though.
Voice is the one above that I'm most excited about - I've had this signed foil DGM copy just staring at me since I've cut it, so I'm excited to get it back in the cube.
I knew I was missing something, largely because this slot underwent a few iterations. While I cut Melira, I also added Renata, Called to the Hunt. Obviously a 2-drop and a 4-drop aren’t equivalent, but it results in the same quantity of enablers, and lets me play an overall more relevant card in both slots.
The evolution of the slot was Yavimaya Elder -> Nightpack Ambusher -> Ripjaw Raptor -> Renata.
Did a virtual cube draft and made a couple additional swaps:
-With the increased blink theme, Clocknapper felt too strong in a way that everyone reported as distinctly unfun. Prior to my recent cube overhaul, it could only really be bounced by Crystal Shard or copied with a clone, which limited the strength of it and likelihood that it would come together. I'm adding Whirler Rogue back in for now as a creature that still benefits from the blink theme, but does it in a way that isn't as unfun.
-Tombstalker felt extremely underwhelming and is showing its age. I'm cutting it for Order of Midnight as a flier for aggro decks, a small flier for midrange decks, and an extra spell for Umori decks.
-Gush is out for Forbid. I had Forbid in before, and added Gush in thinking it would be exciting, but the tempo loss isn't great in my cube.
-Asylum Visitor is out for Liliana, Death's Majesty. Asylum Visitor is fine but still somewhat underwhelming. I like this Liliana a lot, so am going to give her another go.
-Chandra, Flamecaller is out for Chandra, Awakened Inferno. I want to test the M20 Chandra, and this swap seems like the best way to do it.
Dance of the Dead should be in the list. I added it when I went from 495 to 630.
I also like Chandra, Flamecaller slightly more myself, but since I'm just doing virtual drafts for now during lockdown, there's no cost to swapping temporarily, and I don't really want a draft with both of them in it.
FWIW, I've also added Brokkos, Apex of Forever in place of Tasigur to see how it looks in this weekend's draft(s). I'm hopeful, but not optimistic.
Fiddled with a few additional minor changes. I'm cutting most of the nonblue signets (Orzhov and Rakdos are also staying in), and then axing Jegantha, Kaheera, Umori, and Keruga. I think the other 6 companions are fine with the changes to companion, but we'll see.
I always liked Lotleth Troll and Life // Death over Grim Flayer. I'd probably want Qasali Pridemage more than the other two Selesnya cards you are adding, but that would depend on how much artifacts and enchantments are tearing it up.
Life // Death is already in the Golgari section, but I'm down to bring in Lotleth Troll. My experience with both Lotleth Troll and Grim Flayer is pretty limited. Regarding Qasali Pridemage, I didn't really want to have both it andKnight of Autumn taking up two guild slots, but it does increase the chance that one of them makes it into the draft at this size.
I prefer Accorder Paladin to several cards you are running in white: Harmonious Archon, Finale of Glory, Secure the Wastes, Gideon of the Trials, Kjeldoran Outpost. It's a great aggro creature.
Meloku is good enough to stick around on its o wn, but it also combos well with Barrin. I like it more than Thing in the Ice, Sea-Dasher Octopus, Whirler Rogue, one of the Tezzerets, Chart a Course, and Deep Analysis.
I like Berserker more than Immolator, although there probably equal. My cut for Immolator would be Ghirapur Aether Grid or maybe Shrine of Burning Rage.
Regarding Seasoned Hallowblade, I hadn't actually considered cutting something at a different CMC for some reason. I like cutting Finale of Glory here, I think.
For Barrin, I didn't realize the synergy with Meloku. Whirler Rogue was my other consideration, although I'm trying to do more to make artifacts enticing. This is also why Ghirapur Aether Grid is in the cube - I'm testing it to see if it helps with that archetype. If the latter ends up really underperforming, it's a reasonable spot to add Berserker back in. I'll have to think on the other options with Meloku.
Circling back, I made the noted swap above of Finale of Glory and brought Accorder Paladin back in. I still like Harmonious Archon in tokens, and Secure the Wastes has been a much better roleplayer than Finale due to being an instant.
I also decided to cut Deep Analysis to bring back Meloku. I think it's notably below most of the others for me and is also a change that doesn't affect either artifacts or reanimator strategies.
Still on the fence about Aether Grid/Shrine. I agree that making room for the extra creature is probably correct, but haven't had an opportunity to add test either of the other two noted (as they were both added during my cube expansion). It's probably just a question of which is better to keep - although I'm expecting the cut to be Ghirapur Aether Grid.
The switch to Spell Pierce was for a couple reasons - I didn't own a Force of Negation and didn't see myself picking one up too soon, and reading others' experiences with it as on-par with Spell Pierce made me decide to add it back in.
I mostly added Birthing Pod because I really like the new judge foil, and Nightpack Ambusher seemed like a fine card to cut since that was a sort of "up in the air" slot.
I don't think I'd want to lose Manglehorn. I like it better than some of the other cards you are keeping. Maybe cut Beanstalk Giant?
Manglehorn was already a card that was sort of on the line for me in unpowered - there just wasn't another 3-drop I really wanted. Hesitant to cut Beanstalk Giant instead but it might be correct. Beanstalk was a replacement for Kodama's Reach, which I'd still been running, but it's possible I don't need that high a density of that effect.
