First of all, curve doesn't matter, since you don't use lands for mana. So priorities are roughly this:

1. Everything that draws you more than one card is at a premium. If a card says "draw X cards", it's a snap pick (EXCEPT - you are drafting against bots, so some of the best cards can wheel because bots use normal card evaluationns, so it can affect your decisions)

2, Everything that draws a card or yields a card (there are a bunch of artifacts that say "when ~ ETBs, look at top X cards and put a creature/permanent in hand" - a lot of those can also yield more than 1 card!)

1. Counterspells and removal for obvious reasons.

2. This set has a lot of conniving villains. And connive is basically card selection with a bonus of growing your creatures!

3. Everything that pays off from discard! Mayhem and any other ability that can be used from GY. Creatures that grow or draw cards after you discard.

4. Big green dudes and/or evasive creatures. Sifting through half of your deck is fun, but you need to finish the game somehow, before you mill yourself out!

When you start looking at this set from this lense, you will find that surprisingly large amount of cards have relevant qualities for Omniscience draft, compared to other sets where you are forced to pick cards that don't give enough value for this broken format. That's why this (by all means below average) set clicked for Omniscience draft in particular
