Since I never did a post about these sets, here are my additions:

MOM

A good set, but the abundance of double-faced cards means it's less good for this particular cube.

Xerex Strobe-Knight: Not an amazing card, but looks playable. I like the cool overlap with Clarion Spirit and the synergy with the Zephyr Winder.

Zephyr Winder: Just untapping a creature to block is pretty decent, and I have about ten good combos in the cube, from various utility tappers to Exert creatures.

Collective Nightmare: I wanted to round out my Black removal suite with another card that can answer indestructible, but that doesn't work on big things. This one has the excellent upside of sometimes being mana-free.

Halo Forager: Absolutely love this for my Dimir section. This is the first Snapcaster Mage variant we've seen in Peasant, and it's priced to move. It doesn't have flash but it does have a fairly competitive statline.

WOE

Another strong set, with about a dozen cards I seriously considered.

Embereth Veteran: I dislike how wordy Roles are, but I'll pay that price for such a good Red one-drop.

Faerie Dreamthief: Nice card that works well with Ninja, sacrifice, and graveyard themes.

Up the Beanstalk: Good support for a Green ramp strategy (which needs the help).

Picklock Prankster: I like this the most of the defensively-oriented Blue two-drops. And it can grab the new Halo Forager!

Tough Cookie: I have a bit of Clues, Food, and Treasure floating around to feed into this, but mostly, I think this just gets there on its own.

Imodane's Recruiter: Not many Peasant-legal options pack this much power into one card. It felt pretty silly to run Reckless Bushwhacker in my cube when this was out there.

Adding six cards in total from LCI.

Deep-Cavern Bat: Instant staple. One of the most powerful additions to Peasant we've seen in a long time.

Geological Appraiser: Mono-colored Bloodbraid Elf without haste is a great card.

Spyglass Siren: The Blue Thraben Inspector. A really nice get.

Confounding Riddle: Big upgrade to the already-playable Supreme Will.

Bitter Triumph: I like the clean design, the modality, and the minor reanimator support. This is definitely far worse than (e.g.) Go for the Throat, but I'm not looking for 100% optimized Black removal.

Ruin-Lurker Bat: Not sure how long this one will stay, but I want a cheap flying lifelinker in White, and the extra value here is nice.
