I'm a little late here, but the previews for the new set, Torn Asunder, are being released every Monday, Wednesday, and Friday.
Right now Spider are happy with their Ninube, but the lack of any loyalty really jeopardizes their chance of seeing fruition from the strength of the card, especially when you consider Hotako, Gyoken, Aya, Tetsuo, and Shadow Dragon who appear in far more wide reaching decks.
The Lion ancestors got an increase to their gold production, granted Broken Alliance doesn't make its way into every deck in two months, and Paragons got a 7g cavalry personality. Tacticians remain strong and nothing seems to be getting thrown in their paths, so they'll carry right on into March just fine.
The previews for crab are really what the majority of the player base is looking for, but so far I've seen a few previews for a 6g 2f Yoritomo scout who can RA 3 or lower PS by 3, a 7g Scorpion Courtier with cavalry who can give someone Brash, but comes with a 0 HR and 2 PH, an event that acts like Glory but for cheap followers instead of pricey weapons, and a new unique duel card that kills the loser and gives the winner two 1f tokens.
Previews start up on Monday.
