Emblem: "At the beginning of each end step, if no creatures attacked this turn, each player creates a tapped New Planet token." [Or "you create a" and each player gets a separate emblem]

I like that Omniscience draft frees you up to draft whatever rare and exciting cards you see and not worry much about mana fixing, but I feel it's getting kind of degenerate at this point.

The Star Trek set seems like a good opportunity to experiment with a thematic variant - ramping and fixing with New Planet tokens. The emblem rewards being "peaceful", but in a symmetric way that doesnt truly punish players for attacking (it can even be a resource denial strategy in a way). And unlike Omniscience draft with its ~0 land decks, this emblem would play reasonably well with the Landfall and Strange New Worlds mechanics.
