I would love to give you some in depth answers, but I haven't gotten to use my cube in like two months. I started working at my LGS and have to run EDH tournaments on what was previously cube night.
That said, Golgari Germination is a cool card to draft around, but it's pretty slow. I keep it around because I think it's fun.
I have mixed feelings on the cycling lands. They're usually picked somewhere in the middle of the pack; they're perfectly maindeckable, though not really worth picking over a good spell. But, there are too many tapped lands in my cube. They're clogging up packs. I need to cut some of them and the cycling lands are among the leading candidates.
I haven't been able to use the cube in some time (one of the things they don't tell you about getting a job at a game store is that you'll have way less time to play games), but I'm updating my cube anyway. Here are the updates for Shadows Over Innistrad, Eternal Masters, Eldritch Moon, Conspiracy 2, Kaladesh and Commander 2016.
I'm cutting a bunch of cards that can be frustrating and non-interactive. A lot of them are very strong cards that are probably seen as staples, but I want fewer one-sided non-games.
This format is supposed to be fun and these cards do not promote that. The paucity of maindeckable artifact and enchantment removal in peasant cube means a lot of these cards are nearly impossible to remove. Great Oak Guardian and Fire Covenant usually end the game when they get cast. Grafted Wargear is on the watchlist.
The cylcing lands are leaving as well. I love them, but there are already a ton of ETB tapped lands in peasant cube. I may reconsider the lifegain lands as well, but they're staying for now.
The guild sections are getting trimmed by one card each once again. I'm not too sad about any of the cuts, but there are a few that might creep back in at some point. Each color gets one more card and colorless gets five more.
My schedule prevents me from cubing with my normal group, but, as I've gotten to know other groups through working at my LGS, my pool of potential cubists has expanded. So I'm holding my first cube draft in over a year tomorrow.
I've updated the cube with cards from Aether Revolt, Modern Masters 2017, Amonkhet, Hour of Devastation, Ixalan and Iconic Masters (the Rivals of Ixalan cards are in the mail).
I've cut all the cards from non-booster pack products and multiplayer expansions. Most of the cube-worthy cards don't feel like they were designed with a reasonable limited format in mind, so I just don't feel super comfortable having them around.
I'm not including Iwamori of the Open Fist at the moment because his downside is almost non-existent in this format and that doesn't feel right to me. I don't use online rarities, so there are a lot of "peasant" legends missing from my list. Maybe when Dominaria comes out.
