It reveals what appears to be a new Trap Card (Theme unknown, but it’s from a pre-existing recent theme in all likelihood).
But it also names two Deck Themes: クリストロン (Kurisutoron) which appears to have a WATER Synchro Boss, so presumably “Crystron” since Crystals are associated with water in Japan, presumably?
The other is 化合獣 Kagoujyuu, which has a FIRE Xyz Boss apparently. 化合獣 is harder to say, so best guesses are “Compound Beast” or “Chimera Beast”. It’s hard to decide what the name should be until we have examples of the card names to go with.
