Maybe one or two, like Dark Gaia or Infernal Sniper (Ooh. A Hinotama every turn... can't wait for someone to complain about it, though I will laugh at people trying to E-Con it). I personally would like the Deskbot pendulums, especially 005 and 006. As for archetypes, maybe the normal Pendulum support (Flash Knight, Draconia) Performapals or some Igknights? Definitely not something like Amorphage.
They usually release a new box circulating around a new character we just got. But it was just my guess we may get evil hero support or a few more. One of Supreme King skills requires at least 10 evil cards in the deck along with a few other requirements
I want some ritual support, c'mon konami why are you so afraid of supporting rituals? there are only 2 ritual decks capable of KoG and one of them doesn't even use ritual spells
