As well as a better picture of the cover card monster.
This close-up is from the following poster. We still don’t have information on this cover card.
This poster introduces the new theme 十二獣 (Juunishishi), a pun on 十二支 (Juunishi), the twelve signs of the Chinese Zodiac, and 獣 (Shishi), “beasts”. The monsters in the poster seem to be based on the ox, the snake, the horse and the dragon from left to right.
The OCG crew will be further introducing this theme on 9/24 via Youtube.
Addition:
It’s a theme that fights using Xyz Summons, stated to bring new possibilities to Xyz Summoning.
