Not an image post but the precon spoilers are a few days out still and Gavin dropped some hints on R*ddit about the new cards in the decks. Hopefully this kind of post is allowed :D. I’m copying them here because I know you don’t want to have to watch the video:

Hint #1: There is a card that is NOT a planeswalker, which enters with loyalty counters

Hint #2: There is a new card with the adamant ability, originally seen in Throne of Eldraine.

Hint #3: There is a card that can become a legendary 6/6 Nightmare God creature with menace and deathtouch.

Hint #4: The colorless deck isn’t just eldrazi – for example, there’s a new colorless Ikoria monster, and a new Strixhaven Archaic too!

Hint #5: There’s a card I love that was originally designed for Commander 2018 and cut

Hint #6: There’s a new titan, modeled after the M11 titans

Hint #7: There’s a card that turns planeswalkers into birds

Hint #8: There’s a new impetus, in the vein of the onces we originally saw in Ikoria Commander

Hint #9: There’s a legendary card for an obscure flavor text character from Time Spiral block

Hint #10: There is a card named “Guff Rewrites History”

Hint #11: There’s a legendary creature that makes you choose a planeswalker type.

Hint #12: There is a mono blue planeswalker that has never gotten a card before - and no, it’s not one of the Nine Titans!
