They teased a new TCG archetype. Long story short, it's based on Bonz' duel so it heavily focuses on Call of the Haunted and Pumpking.
The field spell sets three CotH from deck or GY, and makes it so CotH also sends an opponent's monster to the GY. And they have a guy that lets you search one and then activate it that turn.

If you don't remember, in the manga CotH just revived every monster from the GY as a zombie every turn and gave them attack buffs. Hopefully Zombies will be good again.
