I had a chance to draft the cube with 5 pals.
Here are the decks drafted with important sideboards on the right.

ub Self-Mill drafted by C • 2-0-0

• Heavily Blue, two Thassa's Oracle wins against me!
• Not much black removal seen or drafted
• Fun for drafter, might be too easy against durdle decks

urg Temur Durdle drafted by me • 0-2-1

• Approached draft as open. Picked 3 Dimir Surveil cards first
• Prioritized lands and fixing, thought I was 4c for a while
Tatyova, Benthic Druid MVP, no distinct winning plays

wb Lifedrain drafted by V • 3-1-0

• Notably V's first time drafting cube. Felt it was easy!
• No soul sister affects, none seen in draft!
• Felt it was easy to achieve 'Gain 3'

rgu Wet Gruul drafted by Z • 0-0-0

• Also prioritized lands and signets, sideboard FULL of fixing
• Mostly Gruul good creatures, splashing blue
• Drafted Embercleave but my 'alter' was not clear. feelsbad.

wg Populate drafted by M • 0-0-1

• Notably first time this deck has been drafted/played
• Some 'better' green cards in sideboard in favor of playing mechanic cards
• Pressured into playing Desolation Twin
• Games were often board-stalled

br Rakdos Aggro drafted by G • 0-0-0

• G was surprised at the ease of finding a lane and feeling good about what they saw available
• Stalled in games (vs lifegain) and was mana screwed once or twice (16 lands)
• Extensive sideboard, perhaps could've been mono-red if opted to, not a better deck though

Overall, a blast of a draft. Informative for how players read signposts and find their 'lane'. A diverse draft with about five true 'archetypes' left untouched.
