Magic: The Gathering Head Designer Mark Rosewater recently confirmed that Guilds of Ravnica will contain a mix of returning and new mechanics, and now what they are thanks to Magic's official Twitch stream.
Here are the mechanics for the five guilds of Guilds of Ravnica set, according to a Redditor:
Selesnya: Convoke- (Only returning mechanic)
Dimir: Surveil- Surveil is like scry but instead of putting on bottom of library, you put it into your graveyard.
Boros: Mentor- When a creature with Mentor attacks, you put a +1/+1 counter on an attacking creature with less power.
Golgari: Undergrowth- Undergrowth abilities care about the number of dead creatures in your graveyard.
Izzet: Jump-Start- You can cast instants and sorceries with Jump-Start from your graveyard by discarding a card, paying the mana cost and exiling the Jump-started card.
As expected of Boros, the mechanic relies heavily on aggressive combat moves. Surveil is useful and it would be interesting to see if the cards with that mechanic would synergize well with Golgari and Izzet's mechanics since they all interact with the graveyard somehow.
I think Undergrowth is the worst of the bunch and Jump-Start will probably be used in Control decks. Convoke is a nice returning mechanic that could help bring back token go-wide strategies. The buy-a-box promo revealed the first new card with Convoke:
