The metagame revolves around 20-25 clans, much more than last year. You can succeed with any deck, but the same rule applies: follow the bans, or counter whatever isn't banned.
The banlist also changed, mainly Olga, Askai, Lehane, Kalindra, Spyke, Azel, Ulrich, Bonnie Ld, several cards from Roots and GHEIST.
Actually the prices deflated a bit, the only OP non-ELO banned 40k+ card is Lizbeth. Kero and Marly don't count.
Numar is outclassed by Eddie, both aren't OP either
